Introduction Thank you for purchasing Proxims Symphony-HRF Cordless Gateway, a member of the Symphony Cordless Networking Suite. The Symphony-HRF Cordless Gateway interoperates with Symphony Cordless Adapters to deliver reliable, hassle-free networking for your laptops and desktops without the use of wires or cables. With the addition of the Cordless Gateway to a Symphony Cordless Network, you can provide high-speed Internet access to Symphony computers from a cable modem, xDSL modem, or ISDN router, or you can connect Symphony computers to an existing Ethernet Local Area Network (LAN). The Cordless Gateway, like the other members of the Symphony Cordless Networking Suite, is based on Proxims award-winning wireless technology used daily by banks, hospitals, and corporations around the world. You can expect this same reliability from the Symphony products in your home or small office. If you have recently upgraded to a form of high-speed Internet access that no longer requires the use of an analog modem, such as ISDN, xDSL, or service from a local cable company, you may be able to provide this high-speed access to all members of the Symphony Cordless Network simultaneously!

The Symphony-HRF Cordless Gateway also provides a convenient solution for consumers who already have an existing Ethernet LAN in their home or small office but also want the increased flexibility and mobility provided by a cordless system. A cordless computer can share files and printers as if it were another member of the Ethernet backbone. Laptops can become free of wires and cables so you can check E-Mail, surf the Internet, or exchange files from anywhere in your home or backyard! Desktop computers in hard to wire locations can now enjoy connectivity with the rest of the network. This manual provides all of the information necessary to install and config-

ure not only the Symphony-HRF Cordless Gateway, but also the Symphony Adapters that you will use in conjunction with this device. However, you may want refer to the Symphony Adapters Users Manual for detailed installation and troubleshooting instructions. 7 Product Family The Symphony-HRF Cordless Gateway is a member of the Symphony Cordless Suite, a family of products which provide a complete cordless networking solution for the home or small office.

When installed, the Symphony PC Card can communicate with other Symphony products to create a cordless network in the home or small office. The PC Card ships with a snap-on antenna which connects directly to the side of the card. The Symphony PNP ISA Card fits into a standard ISA slot in a desktop computer. The ISA Card is a Plug-and-Play device;

therefore, Windows 95 or Windows 98 will automatically recog-

nize the card and begin the installation process. When installed, the Symphony ISA Card can communicate with other Symphony products to create a cordless network in the home or small office. The ISA Card ships with a desktop antenna which connects to the back of the card with a 5-foot antenna cable. The Symphony PCI Card fits into a standard PCI slot in a desktop computer. The PCI Card is a Plug-and-Play device;

therefore, Windows 95 or Windows 98 will automatically recog-

nize the card and begin the installation process. When installed, the Symphony PCI Card can communicate with other Symphony products to create a cordless network in the home or small office. The PCI Card ships with a desktop antenna which connects to the back of the card with a 5-foot antenna cable. 8 q q q The Symphony USB Adapter connects to a computers USB

(Universal Serial Bus) port. The Symphony USB Adapter is a Plug-and-Play device; therefore, Windows 98 will automatically recognize the adapter and begin the installation process. When installed, the Symphony USB Adapter can communicate with other Symphony products to create a cordless network in the home or small office. The Symphony USB Adapter has a built-in antenna and includes a 6-foot cable to connect the adapter to a computers USB port. The Symphony Cordless Modem is a 56 Kbps modem (V.90 and x2-compatible) which plugs into any standard phone jack. The Symphony Cordless Modem provides high speed, analog modem access to any other Symphony-enabled computer in the house-

hold, and it frees desktops and laptops so that they no longer need to be located near a telephone jack. The Cordless Modem has a built-in antenna. Note that the Cordless Modem cannot be used in conjunction with the Symphony-HRF Cordless Gateway. Proxim ships several software tools on the Symphony Installation CD-ROM to make installation and configuration simple and hassle-free. q q The Symphony Composer Installation Wizard guides the user through the setup and configuration of a Symphony Cordless Network during the initial installation or following an upgrade from an earlier version of the Symphony software. The Symphony Maestro Configuration Tool allows the user to configure the settings and monitor the status of the Symphony Cordless Network and Cordless Gateway. The Symphony Network Switcher provides a fast and convenient way to transport a Symphony-enabled computer between different networks by storing the relevant settings for each network. 9 q q q In addition, Proxim offers Symphony accessory products, such as additional antenna options for the Symphony PC Card, and spare parts. Refer to Proxims Symphony Web site, at http://www.proxim.com/symphony/, for information on available accessories. System Requirements In order to use a Symphony-HRF Cordless Gateway, you must have the following:

An external, Ethernet-ready device which provides high-speed Internet access, such as a cable modem, xDSL modem, or ISDN router. When attached to this device, the Cordless Gateway will allow Symphony-enabled computers to share Internet access;

OR A 10BaseT Ethernet hub or a computer with an Ethernet card already installed. When attached to one of these devices, the Cordless Gateway will allow Symphony-enabled computers to communicate with devices on a wired Ethernet network or to a single, stand-alone Ethernet-ready computer. At least one Symphony Adapter installed in a Windows 95 or Windows 98 computer with a minimum 486/66 MHz processor, a minimum of 16 MB of RAM, and a minimum of 10 MB of hard disk space available. 10 q q q The Product Package Each Symphony-HRF Cordless Gateway comes with the following:

One (1) Symphony-HRF Cordless Gateway with an integrated antenna. One (1) 7.5 Volt, 1 Amp power adapter. One (1) 10BaseT crossover cable. See Appendix A for important information regarding the Cordless Gateways cabling require-

ments. One (1) Symphony-HRF Cordless Gateway Quick Start Guide. One (1) Symphony-HRF Cordless Gateway Users Manual. 11 q q q q q 2. Cordless Networking With the Cordless Gateway The Symphony Adapters create a cordless network between each computer in a household using standard networking software included with Windows 95/

98. This network links the computers together so that they can share files, printers, and other peripheral devices, such as CD-ROM drives, floppy disk drives, or Iomega Zip drives. With the addition of a Symphony-HRF Cordless Gateway to the cordless network, the Symphony Cards can also communicate with a small existing Ethernet network or with an external Ethernet device that provides high-speed Internet access. The Cordless Gateway provides a cordless solution for a wide variety of small networking environments, including these four supported configura-

tions:

Cordless connectivity to an external Ethernet-ready device which provides high-speed Internet access;

Cordless connectivity to an existing Ethernet network;

q Cordless connectivity to an existing Ethernet network that is capable of accessing the Internet at high speeds; and Cordless connectivity to a network server. Each configuration is described in detail below. Also, see Chapter 7 for more information on how to configure the cordless network in each of these scenarios. Connectivity to an External Ethernet Device Which Provides High-Speed Internet Access The Symphony-HRF Cordless Gateway allows the cordless network to communicate with an external Ethernet device to share high-speed Internet access with every Symphony-enabled computer. The Cordless Gateway acts as a link between a high-speed Internet device and the Symphony-enabled computers, so that each computer (laptops and desktops) on the cordless network has simultaneous Internet access and can share files and printers. 12 q q q To use the Cordless Gateway in this configuration, you need a high-speed Internet account with an Internet Service Provider (ISP) and one of the following pieces of equipment:

An external cable modem;

An external xDSL device, such as an ADSL modem;

An ISDN router; or Any other external Ethernet device that can provide high-speed Internet access to a network. Note that these devices must be external, stand-alone units that support 10 Mbps Ethernet and have an RJ-45 10BaseT connector; devices which use a different networking technology, such as ATMF-25, will not communicate with the Cordless Gateway. For a similar reason, most ISDN terminal adapters cannot be used with the Cordless Gateway because they do not communicate over Ethernet and do not have a 10BaseT Ethernet port. Generally, you will use the 10BaseT crossover cable, included in the product package, to connect the Cordless Gateway to your high-speed device. Devices such as an ISDN router, which often include several hub ports built-

in, or a cable modem, which is designed to connect to a single Ethernet card installed in a computer, are wired like a 10BaseT cabling hub. The Cordless Gateway is also wired like a 10BaseT cabling hub, so in order to connect two devices that are both wired like a hub together, you must use a 10BaseT crossover cable. If your high-speed device is wired like a standard Ethernet card, then you need to use a standard 10BaseT cable to connect the Cordless Gateway and this device. See Appendix A for more information on the Cordless Gateways cabling requirements. In this configuration, the Cordless Gateway performs a function known as Network Address Translation or NAT. The ISP assigns a single IP Address for the Cordless Gateway, and NAT allows up to ten (10) Symphony-

enabled computers to access the Internet at the same time using this single address assignment. The Cordless Gateway acts as an intermediary and sends data between the Internet and the computers on the Symphony Cordless Network. 13 q q q q By default, the Cordless Gateway is configured to accept a dynamic IP Address from a DHCP (Dynamic Host Configuration Protocol) server. If your ISP does not use DHCP, then you will need to configure the Cordless Gateway with a static IP Address assigned to you by the ISP. See Chapter 7 for more information on how to configure the Cordless Gateways TCP/IP parameters. Connectivity to an Ethernet Network If you have a small network already in your home or office, you can connect the Symphony-HRF Cordless Gateway directly to an Ethernet cabling hub in order to provide connectivity between computers on the cordless network and nodes on the wired Ethernet. The Cordless Gateway transparently links the two networks so that to each node there appears to be only one network. This function is known as Transparent Bridging. Simply connect the Cordless Gateway to the 10BaseT cabling hub using the 10BaseT crossover cable included in the product package. In order to connect two devices that are both wired like a hub together, you must use a 10BaseT crossover cable. See Appendix A for more information on the Cordless Gateways cabling requirements. In this configuration, each computer, whether wired or cordless, will have the ability to share files and printers with the all other members of the cordless and wired networks. For example, if you have an existing wired Ethernet, you may add a Cordless Gateway to give network connectivity to a laptop with a Symphony PC Card installed. By default, the Cordless Gateway performs both Network Address Transla-

tion (NAT) and Transparent Bridging. Depending on the configuration of your network, you may want to disable the NAT function. See Chapter 7 for information on how to configure the Cordless Gateway and for more informa-

tion on File and Printer Sharing. 14 Note:

The Cordless Gateway is designed to provide connectivity to small Ethernet networks. It cannot support more than eight (8) devices on its Ethernet port. Do NOT connect the Cordless Gateway to a cabling hub that has more than eight (8) Ethernet devices attached. Connectivity to an Ethernet Network Which Has High-Speed Internet Access As discussed above, an Cordless Gateway can link a Symphony Cordless Network to a wired Ethernet network. In addition, if you have an existing device on the wired network which provides high-speed Internet access to each of the Ethernet workstations, then the Symphony-enabled computers will also be able to share this Internet connection. Examples of high-speed devices include a cable modem, an ADSL modem, or an ISDN router. The presence of the Cordless Gateway allows the two networks to be linked together sharing this Internet access as well as files and printers. Note:

The Cordless Gateway is designed to provide connectivity to small Ethernet networks. It cannot support more than eight (8) devices on its Ethernet port. Do NOT connect the Cordless Gateway to a cabling hub that has more than eight (8) Ethernet devices attached. Simply connect the Cordless Gateway to the 10BaseT cabling hub using the 10BaseT crossover cable included in the product package. In order to connect two devices both wired like a hub together, you must use a 10BaseT crossover cable. See Appendix A for more information on the Cordless Gateways cabling requirements. In this configuration, the Cordless Gateway may perform Network Address Translation (NAT), Transparent Bridging, or both. By default, the Cordless Gateway will perform both tasks, but depending on your network configura-

tion, you may wish to change this setting within the Symphony Maestro Configuration Tool. For example, if you already have an Internet-sharing software package, such as a proxy server program, installed on the network, you may configure the Cordless Gateway to perform Transparent Bridging only and then configure the Symphony-enabled computers with TCP/IP 15 settings that match the TCP/IP settings of the workstations on the existing wired network. Refer to Chapter 7 to learn how to configure the Cordless Gateway and for a discussion of suggested TCP/IP configurations for the network. Connectivity to a Network Server You may also connect the Cordless Gateway to an existing Ethernet network that contains a network server, such as a Windows NT server, to allow Symphony-enabled computers to act as network clients. Simply connect the Cordless Gateway to the 10BaseT cabling hub using the 10BaseT crossover cable included in the product package. In order to connect two devices that are both wired like a hub together, you must use a 10BaseT crossover cable. See Appendix A for more information on the Cordless Gateways cabling requirements. In this configuration, Symphony-enabled computers should have the same client/server and file sharing capabilities as any existing wired clients on the network. The Cordless Gateway performs Transparent Bridging to link the two networks so that to each node there appears to be only one local area network (LAN). By default, the Cordless Gateway performs both Network Address Translation (NAT) and Transparent Bridging. Depending on the configuration of your network, you may want to disable the NAT function. See Chapter 7 for information on how to configure the Cordless Gateway. Note:

The Cordless Gateway is designed to provide connectivity to small Ethernet networks. It cannot support more than eight (8) devices on its Ethernet port. Do NOT connect the Cordless Gateway to a cabling hub that has more than eight (8) Ethernet devices attached. In addition, if you do not have an existing network and desire only to connect cordless clients to one stand-alone server, you can also attach the Cordless Gateway directly to the server. Simply connect the Cordless Gateway to an Ethernet card installed in the server using a standard 10BaseT cable. You will have the same functionality between the server and cordless clients as described above. 16 3. Installing the Symphony Hardware This chapter describes the step-by-step procedure for the physical installa-

tion of the Symphony-HRF Cordless Gateway and the Symphony Adapters. Symphony-HRF Cordless Gateway The Symphony-HRF Cordless Gateway is a stand-alone device which requires no software installation. Also, the Cordless Gateway includes an integrated antenna so there is no separate antenna installation required. Follow these steps to install the Cordless Gateway:

1. Place the Cordless Gateway in close proximity to the Ethernet-ready device to which you intend to attach the unit. If you intend to use the 10BaseT crossover cable included in the product package, the distance between the Cordless Gateway and the 10BaseT port of the Ethernet-ready device must not be greater than the length of this cable. If you intend to use your own 10BaseT cable, the cable must not exceed 100 meters. In general, you should try to place the Cordless Gateway on top of a desk or bookcase so that it is as far from the ground as possible, keeping clear of metal obstructions. You should also try to centrally locate the device so that it will provide coverage to all of the computers on the cordless network, but keep in mind that it must also be close enough to the wall so that you can easily connect its power adapter to the wall outlet. 2. Attach one end of the power adapter to the back of the Cordless Gateway and the other end to the wall outlet. The Status LED, located on the top of the Cordless Gateway, should glow yellow and then green to indicate that the unit is operational. Note:

Use the Symphony-HRF Cordless Gateway only with the power adapter supplied by Proxim in the product package. Using another power supply may damage the Symphony-HRF Cordless Gateway. 3. Attach one end of the 10BaseT crossover cable, provided in the product package, to the Cordless Gateway and attach the other end to the 10BaseT 17 port of an Ethernet-ready device. Make sure that the Ethernet-ready device is powered on before proceeding. Once the cable is attached to both devices, the Cordless Gateways green Link LED should illuminate. This LED lights up when an Ethernet link is detected and, on occasion, will blink off momentarily to reflect Ethernet activity. However, if the Link LED does not light up and remain on (only blinking off momentarily) when the cable is attached, then the 10BaseT crossover cable is not the correct cable for this connection. In this case, you need to obtain a standard 10BaseT cable in order to connect the Cordless Gateway to the Ethernet-ready device. Do not proceed to Step #5 until the Cordless Gateways Link LED lights up and remains on (only occasionally blinking off to reflect Ethernet activity). In general, you will use the 10BaseT crossover cable, provided in the product package, to connect the Cordless Gateway to a high-speed Internet device, such as a cable modem, xDSL modem, or ISDN router, or to a free port on an Ethernet hub. However, use a standard 10BaseT cable to connect the Cordless Gateway to a single, stand-alone computer that has an Ethernet card installed or to a standard Ethernet router; do NOT use the cable shipped with the product. See Appendix A for more information about the Cordless Gateways cabling requirements. 5. Proceed with the installation or software update of the other Symphony products in your home or small office using the Symphony Installation CD supplied with the Symphony Adapters. Refer to Chapters 3, 4, and 5 within this manual for instructions on how to install a Symphony Adapter in a Windows 95/98 computer. Refer to Appendix C for instructions on how to install a Symphony Adapter in a Windows NT computer. The Sym-

phony-HRF Cordless Gateway must remain powered on during the installation of the other Symphony products. Note:

If the Cordless Gateway is not powered on when installing or updating the other Symphony components on the cordless net-

work, you will have difficulty configuring these other Symphony products. 18 LED Indicators The Symphony-HRF Cordless Gateway has five functional LEDs: three on the top of the unit and two on the back panel. The LEDs on the top panel perform the following functions:

The Status LED, which is located on the right side when the unit is orientated so that you can read the Symphony logo, changes colors from yellow (initializing) to green (operational). If the LED turns red, try recycling power to the Cordless Gateway. If the LED remains red, contact Symphony Technical Support for assistance. The Cordless Network Activity LED, in the center, blinks yellow when the Cordless Gateway receives data from the cordless network. The Ethernet LED, on the left side, blinks green when the Ether-

net Bridge receives data over the 10BaseT Ethernet connection. The LEDs on the back panel perform the following functions:

The green Link LED, located to the right of the 10BaseT connector, illuminates when a physical connection exists between the Cordless Gateway and an attached Ethernet-ready device. However, this LED reflects Ethernet activity as well as link integrity. Therefore, when a proper 10BaseT cable is attached and there is Ethernet activity, the LED will blink off momentarily;

when a damaged or improper 10BaseT cable is attached and the unit attempts to send data through its Ethernet port, the LED will blink on momentarily. The green Master LED, located to the left of the DC power jack, illuminates when the Cordless Gateway is operational 19 q q q q q Symphony Adapters Symphony PNP ISA Card The Symphony PNP ISA Card fits into a 16-bit ISA-bus slot in your com-

puter. The ISA slot is typically a black plastic casing surrounding two rows of gold connectors on the computers motherboard. If you cannot identify an ISA slot, refer to your PCs manual for assistance. Follow these steps to install the ISA Card and the antenna:

1. Turn off your computer and unplug its power cord from the wall outlet for safety purposes. 2. Remove the computer cover. 3. Locate an unused ISA slot and refer to your PCs manual for instructions on how to remove the plate that covers the slot, if one exists. 4. Align the Symphony ISA Card over the empty slot.

Place the antenna on top of your desk, computer, or monitor. 9. Turn on the computer and refer to the software installation procedure described in Chapter 4. 21 Symphony PC Card The Symphony PC Card fits into a standard Type II PCMCIA slot in your computer. Follow these steps to install the PC Card and the antenna. 1. Locate the antenna connector on the end of the PC Card. 2. Attach the snap-on antenna to the PC Cards antenna connector. 3. Shut down your laptop or notebook computer. 4. Insert the PC Card into the laptop or notebook computer. 5. Turn on the laptop or notebook computer and refer to the software installation procedure described in Chapter 4. Note:

Do not remove the Symphony PC Card from the PCMCIA slot while the computer is operational without first stopping the card. Go to the PC Card (PCMCIA) icon in the Control Panel and highlight the Symphony PC Card entry. Click <Stop> and remove the card when prompted. Symphony USB Adapter The Symphony USB Adapter is very easy to install. The USB Adapter has a built-in antenna so the antenna does not require installation. Also, the USB port powers the adapter so the USB Adapter does not require a power cable. Follow these steps to install the USB Adapter. 1. Place the USB Adapter on top of your desk, computer, or monitor. 2. Connect the USB Adapters cable to a free USB port on the computer. 3. Turn on the computer and refer to the software installation procedure described in Chapter 4. 22 4. Installing the Symphony Software The Symphony-HRF Cordless Gateway requires no software installation. However, you must load Symphony software on each computer in which you installed a Symphony Adapter. The software installation for a Symphony Adapter occurs in two phases. The first phase, described in this chapter, is the successful initialization of a Symphony Adapter in a desktop or laptop computer. The second phase, described in Chapter 5, configures a computer to communicate with the rest of the cordless network using the Symphony Composer Installation Wizard to guide you through the process. The following procedure provides an overview of how to install a Symphony Adapter in a Windows 95/98 computer. For detailed instructions and troubleshooting suggestions, refer to Chapter 4 of the Symphony Adapters Users Manual. Once the software has been successfully installed, refer back to Chapter 5 of this manual for configuration instructions. If you have an existing Symphony Cordless Network and now want to upgrade the network to include a Symphony-HRF Cordless Gateway, refer to Chapter 9 for instructions. For information on how to upgrade a Cordless Gateways firmware or the Symphony software for Cordless Gateway clients, refer to Chapter 10. If you are planning to install Symphony software on a computer equipped with a Proxim RangeLAN2 Card that already has the RangeLAN2 driver loaded, proceed to Appendix B for specific installation instructions. Finally, before beginning the installation of a Symphony Adapter, confirm that you have a Windows CD or diskettes available (either Windows 95 or Windows 98, depending on the computers operating system). You will be prompted to insert a Windows CD during the installation. If you do not have a Windows CD or diskettes, it is possible that you already have the Windows 95 or Windows 98 installation files on your hard disk. These Windows installation files are known as Windows Cabinet files or CAB files. The Windows Cabinet files are commonly located in C:\WINDOWS\OPTIONS\CABS. 23 Warning!

You must have either the Windows CD, diskettes, or Cabinet files to complete the installation of the Symphony Card. Do NOT proceed with the installation until you have confirmed that you have one of these Windows 95 or Windows 98 installation media available. Follow these steps to install Symphony software on a computer running Windows 95 or Windows 98. 1. Install the Symphony Adapter hardware as described in Chapter 3. 2. Turn on the computer. Windows 95/98 will automatically detect the new device. Windows will recognize the Symphony PC Card as a PROXIM-

LAN PC CARD, the Symphony PCI Card as a PCI Network Controller, the Symphony PNP ISA Card as a Symphony Cordless PnP ISA Card, and the Symphony USB Adapter as a Symphony USB Adapter. 3. Choose <Cancel> to close the Windows 95/98 installation wizard. 4. When the Windows (95 or 98) desktop appears, insert the Symphony Installation CD, shipped with the Symphony Adapter, into the computers CD-ROM drive. 5. The Symphony Installation program will be launched automatically and display the following dialog box:

24 However, if this screen does not appear, then go to the My Computer icon on the Windows desktop and double-click the drive letter that corresponds to the CD-ROM drive (typically, this is drive D) to browse the Symphony Installation CD. Double-click the icon labeled SETUP.EXE to manually launch the Setup program. 6. Click <Install Now> to continue with the standard installation. By default, the Symphony installation files are copied to a directory named C:\PROGRAM FILES\SYMPHONY. If you want the Symphony files to be installed in a different directory, click the <Customize> option and then choose the <Change Folder> option to select a new destination folder. Click

<Next> to continue. 7. Regardless of whether you chose the <Install Now> option or the <Cus-

tomize> option, you will now be prompted to choose the adapter type that matches your Symphony Adapter. Place a check mark next to the entry for the Symphony PC Card, the Sym-

phony PNP ISA Card, the Symphony PCI Card, or the Symphony USB Adapter (depending on the type of card being installed) and click <Install Now>. If you are using a product not on the list, place a check mark next to the entry labeled Others ... to view additional options. 25 8. Please be patient while the installation program copies the necessary Symphony installation files from the Symphony CD. 9. Insert your Windows 95 or Windows 98 CD if prompted. If you do not have a Windows CD, but you have Windows diskettes or the computer has the Windows Cabinet files, direct Windows to look for the Windows files in the Cabinet directory, which is typically located in C:\WINDOWS\OPTIONS\CABS\. Note:

If the installation wizard cannot locate a particular file, do NOT skip the file. Instead, try to locate the file on the Windows CD, within the Windows CAB directory, or within the C:\Windows\

and C:\Windows\System directories. In order for the Symphony Adapter to install correctly, the installation wizard must find and copy all of the files that it is looking for. 10. The computer will copy all of the Windows files required to complete the installation of the Symphony Adapter. If the computer prompts you that a file you are copying is older than the one currently on the system, keep the existing file by clicking the <Yes> button. 11. The Symphony Installation program will report when the installation has been successfully completed. Restart the computer when prompted. 12. Windows will make some final adjustments to the system. Leave the Windows CD in the CD-ROM drive: Windows may need to copy additional files from the CD. Restart the computer a second time if prompted. 13. After the computer restarts, you may be prompted to enter either a Windows password or a network password before proceeding. If you have an existing User name and Password, type in the Password and click <Enter>, or simply click <Enter> if your Password is blank. This step will enable the computers network functionality. Do NOT choose the <Cancel> option. Also, write down your User name and Password for future use; you will need to enter this information each time you logon to the cordless network. Note:

You must enter a User name and Password to logon to the network. If you choose <Cancel>, you will be unable to access network resources. 26 14. The Symphony Composer Installation Wizard will now initialize and display the Welcome message. Proceed to Chapter 5 for information on how to use the Symphony Composer Installation Wizard. If the Symphony Composer Welcome message does not appear, or if you are prompted that the Symphony Adapter is not working properly, refer to the troubleshooting procedure in Chapter 4 of the Symphony Adapters Users Manual that ships with each Symphony Adapter. Once the adapter has been successfully installed, refer back to Chapter 5 of this manual for configura-

tion instructions. Hint:

If you have problems installing a Symphony Adapter, refer to Chapter 4 of the Symphony Adapters Users Manual for detailed installation and troubleshooting instructions. 27 5. Symphony Composer Installation Wizard The installation of a cordless network occurs in two phases. The first phase, described in Chapter 4, is the successful initialization of a Symphony Adapter in a desktop or laptop computer. The second phase configures a computer to communicate with the other devices on the cordless network. The Symphony Composer Installation Wizard guides you through the second phase of the installation process. Once a Symphony Adapter has been successfully initialized, the Symphony Composer will be launched automatically and display the Welcome screen, shown below. The Symphony Composer provides a friendly user interface to make configu-

ration fast and easy. Each configuration option is explained in detail as you navigate through the Composers installation screens. Be sure to read all of the on-screen instructions carefully before making a selection and proceed-

ing to the next screen. At any time, you may choose the <Back> button to return to an earlier screen and change a previous selection. Note:

Confirm that the Cordless Gateway is powered on before pro-

ceeding with the configuration of the Symphony-enabled com-

puters. 28 Click <Next> to begin configuring the Symphony network. Step 1: Select a Security Code The Symphony Composer will prompt you to choose a Security Code for the cordless network, as shown below. A Security Code is a string of up to 20 alphanumeric characters stored on all communicating Symphony devices. This string must match on all Sym-

phony products to achieve communication. You must use the same Security Code on each Symphony device, and the Security Code is case sensitive. When configuring the first Symphony-enabled computer on a network, enter a Security Code that will be easy for you to remember and click <Next>. The Symphony-HRF Cordless Gateway will adopt this Security Code. Remember to use the same Security Code when configuring the other Symphony-

enabled computers on the network. 29 Step 2: Establish Communication With the Cordless Gateway After you have configured the Security Code, the Composer will attempt to automatically detect the Symphony-HRF Cordless Gateway and test the wireless link, as shown below:

Click <Next> to continue and proceed to Step 3. If the Composer cannot communicate with the Cordless Gateway, it will prompt you to manually select a network configuration, as shown below. 30 If this screen appears, then the Cordless Gateway is not powered on, the Security Code you entered does not match the Cordless Gateways Security Code, or the computer is out of range of the Cordless Gateway. If you have previously configured other Symphony-enabled computers on the network, confirm that you are using the correct Security Code. Also, try to bring the computer and the Cordless Gateway closer together before proceeding. Select the option labeled I have a Proxim Symphony-HRF Cordless Gate-

way and click <Next>. You will be prompted to confirm that the Cordless Gateway is powered on and operational, as shown below. 31 Confirm that the Cordless Gateway is powered on and operational and click

<Next> to continue. If the Composer cannot locate the device, you will be prompted to reenter the Security Code. If this is not the first Symphony-enabled computer you are configuring, confirm that the Security Code is correct and click <Next> to continue. If the Composer still cannot locate the Cordless Gateway, it will prompt you to enter the last six (6) digits of the devices serial number, as shown below. 32 The serial number is located on the underside of the Symphony-HRF Cordless Gateway. Enter the last six digits of the serial number and click

<Next>. The Symphony Composer should now be able to communicate with the Cordless Gateway and should perform a link test. Click <Next> to continue. However, if problems persist, try moving the Cordless Gateway and the computer closer together; the computer may be out of range of the Cordless Gateway. Also, you may want to contact Symphony Technical Support for assistance and additional suggestions. Step 3: Configure TCP/IP Information When configuring the first Symphony-enabled computer on a network, the Cordless Gateway will request IP Addressing information from your ISPs DHCP (Dynamic Host Configuration Protocol) server. 33 If the Cordless Gateway cannot receive an IP Address from the ISPs DHCP Server, the Composer will prompt you to enter the static TCP/IP information assigned to you by the ISP (Internet Service Provider), as shown below. If you believe that your ISP uses DHCP to assign dynamic IP Addressing information, place a check mark next to the box labeled Use DHCP and click <Next> to continue. Otherwise, enter the TCP/IP parameters assigned to you by the ISP into the fields provided. This includes IP Address, Subnet Mask, Gateway address, and primary and secondary DNS addresses, if applicable. If you do not have this TCP/IP information, contact your ISP for assistance. If you plan to use the Cordless Gateway in Transparent Bridging mode only to communicate with a wired Ethernet network, leave these fields blank and click <Next> to continue. Refer to Chapter 7 for more information on these parameters. 34 If you have previously configured the Cordless Gateways TCP/IP informa-

tion, the Composer will give you the option to change the existing settings, as shown below. If you do not wish to change any TCP/IP information at this time, select the No, dont change the Cordless Gateway settings at this time option and click <Next>. Step 4: Assign a Computer Name In a peer-to-peer network, each computer is assigned a name so that it can be easily identified by the other devices on the network. The Symphony Composer Installation Wizard will determine if your computer has already been assigned a name. If a name is not found, the Symphony Composer will prompt you to give the computer a name. The computer name may be up to 15 alphanumeric characters long. 35 Step 5: Select Drives and Printers to Share The Symphony Composer will generate a list of the computers hard drives, CD-ROM drives, floppy drives, and printers that may be shared with other computers on the cordless network. Simply check the box to the left of each resource entry to allow other computers to access that particular resource over the network, as shown in the example below. Note that if you click the box to the left of a resource multiple times you can toggle between several access levels that may be granted to remote users. The options are Read/Write access, Read Only access, or no access. If you configure a drive with Read/Write or Read Only access, Proxim recommends that you establish a password to prohibit unauthorized access. Depending on the type of Internet connection you have, others may be able to see your computers in their Network Neighborhood and have unauthorized access to your drives. You may change the access type and establish passwords using the Sym-

phony Maestro Configuration Tool. See the File Sharing discussion in Chapter 7 for details. 36 Step 6: Configure Switcher Prompt at Boot-up The Symphony Network Switcher program includes an optional DOS prompt that will appear each time the computer boots up; this is a convenient method to switch between network profiles for users who frequently transport a laptop between networks. Depending on the configuration of the com-

puter, the Symphony Composer Installation Wizard may prompt you to decide whether or not want this prompt to appear each time the computer boots up, as shown below. If you decide later that you want to enable or disable the Switcher DOS prompt, you can reconfigure this feature within the Network Switcher configuration screen. See Chapter 8 for more information on the Network Switcher. When you have completed the configuration of the Symphony settings described above, restart the computer if prompted. 37 Step 7: Register Symphony Products Following the successful completion of the Symphony Composer Installa-

tion Wizard, you will be given an opportunity to register your Symphony product on-line, as shown below. Click <Yes, Register Now> to be taken to the Symphony Registration Web site. If you choose not to register at this time, you can click the <Remind Me Later> button to be prompted each time you turn on or restart the computer. If you do not want to be prompted to register again, click <No, Thank You>. Alternatively, you may register at any time by right-clicking the Symphony icon, located in the Windows System Tray. Choose About from the drop-

down list and then click <Register>. Hint:

The Composer may be relaunched at any time from the Symphony group under the Programs section of the Start Menu to reconfigure the cordless network. See Chapter 9 for more information on how to reconfigure a cordless network. 38 6. Symphony Maestro Configuration Tool The Symphony Maestro Configuration Tool lets you make changes to the cordless network and monitor its current status. After the Composer completes the installation of the cordless network, the Maestro Configuration Tool will display a Symphony icon in the Windows System Tray, as shown below:

Double-click the Symphony icon to launch the Maestro tool. Alternatively, right-click the Symphony icon and choose Status, as shown below. Either method will launch the Maestro Configuration Tool, shown below. 39 The Maestro tool has two functions: it monitors the current state of both the cordless network and the Cordless Gateway, and it allows the user to reconfigure the cordless network and Cordless Gateway parameters. Below is a brief overview of the key features incorporated into the Maestro Configuration Tool when using the Symphony-HRF Cordless Gateway. Refer to the Online Help documentation for additional details on how to use each of these features and for information on additional features not dis-

cussed below. Maestro Features for the Cordless Gateway The Symphony Maestro allows you to configure and monitor the following Cordless Gateway functions:

Monitor the State of the Cordless Gateway On the main page of the Maestro Configuration Tool, under the Symphony-

HRF Cordless Gateway heading, there is a picture of the Cordless Gateway which will change color to reflect different states of connectivity. When the Cordless Gateway icon is turquoise, the Symphony-enabled computer is successfully communicating with the Cordless Gateway. When the Cordless Gateway icon is red, the computer cannot communicate with the Cordless Gateway, typically because the Cordless Gateway is not operational, the computer is out of range, or the Security Codes do not match. Note that the Symphony icon in the Windows System Tray will also change color to reflect different states of radio connectivity. Configure the Cordless Gateway to allow Internet Sharing The Cordless Gateway can perform both Transparent Bridging and Network Address Translation (NAT). By default, the Cordless Gateway performs both these functions and will accept an IP Address from a DHCP server. You may change these values by clicking the <Configure> button under the Symphony-HRF Cordless Gateway heading. From this screen, you may configure the Cordless Gateway with static TCP/IP settings assigned by your ISP and configure the device to perform NAT, Transparent Bridging, or both. 40 In addition, you may configure the TCP/IP Addressing scheme that the Cordless Gateway uses to communicate with Symphony-enabled computers when operating in NAT mode. See Chapter 7 for detailed information on these parameters. Upgrade the Symphony-HRF Cordless Gateway If a new firmware file becomes available for the Symphony-HRF Cordless Gateway, you may upgrade the unit to this new version using the Maestro Configuration Tool. Click the <Configure> button under the Symphony-

HRF Cordless Gateway heading and click the <Upgrade> tab to display the Upgrade screen. This screen displays the current version of the Cordless Gateways firmware and allows you to upgrade the firmware version on the Symphony-HRF Cordless Gateway either from a file on a diskette or from the Symphony Web site. Refer to Chapter 10 for detailed upgrade instructions. Monitor the Cordless Gateways Status A user may monitor the status of the Cordless Gateways TCP/IP settings from the ISP by clicking the <Status> button under the Symphony-HRF Cordless Gateway heading. Among other things, the Cordless Gateway Status screen reports whether or not the Cordless Gateway successfully received an IP Address from a DHCP server, as shown below. Refer to Chapter 7 for more information on these parameters. 41 Maestro Networking Features The Symphony Maestro Configuration Tool allows you to configure and monitor the following network functions:

Obtain Network Status Information The Symphony Maestro Configuration Tool reports the number of packets sent and received by the Symphony Adapter while communicating with the cordless network. Click the <Status> button under the Symphony Network Status heading to view the Cordless Status screen shown below. Test Cordless Connection The Symphony Maestro reports the identities of the other members of the cordless network in the Symphony Network Map. You may test the strength of the cordless connection between your computer and any other member of the cordless network. Simply highlight one of the other computers in the Symphony Network Map, as shown below. 42 Click <Select> to perform the link test, as shown below. 43 Maestro will rate the connection strength as Excellent, Good, or Poor, depending on the results of the test. Double-clicking one of the entries will also open the Test Cordless Connection window. Configure Network Parameters From within the Maestro Configuration Tool, you may change the Security Code and which drives, directories, and printers are available for sharing by clicking the <Configure> button under the Symphony Network Status heading. This will display the computers Setup screen, as shown below. Click the appropriate tab to change which drives, directories, and printers are available for sharing. Note that the Maestro Configuration Tool allows you to designate specific directories to share. Therefore, rather than sharing an entire drive, you can customize the amount and location of information that is available to other users on the network. Refer to the section entitled File Sharing in Chapter 7 for additional details. 44 Remote Drive Sharing The Symphony Maestro allows you to attach a remote shared drive or directory to a drive letter on the local computer. Highlight one of the other Symphony computers in the Symphony Network Map and click <Select> or simply double-click one of the entries. Then, click the Remote Drive Sharing tab to utilize this feature. Refer to the section entitled Remote Drive Sharing in Chapter 7 for additional information about this feature. Maestro Administrative Features The Symphony Maestro Configuration Tool also includes the following administrative features:

Determine Software Version in Use To view information about the Symphony software versions currently in use, right-click the Symphony icon in the Windows System Tray and choose About, as shown below. This will display the About Symphony Maestro Configuration Utility screen, as shown below. 45 Register Products on Proxims Web Site At any time you may register your Symphony products on-line at Proxims web site. If you did not register your Symphony products following the completion of the Symphony Composer Installation Wizard, simply click the

<Register> button in the About Symphony Maestro Configuration Utility screen, shown above, to be taken to the Symphony Registration Web site. 46 7. Configuring a Cordless Gateway Network This chapter describes how to configure the Cordless Gateway to allow Symphony-enabled computers to share a high-speed Internet connection and/or communicate with devices on a wired Ethernet network. In addition, this chapter includes instructions for how to share files between computers using the Maestro Configuration Tool and how to print to a network printer. Cordless Gateway Configuration From within the Symphony Maestro Configuration Tool, a user may config-

ure the TCP/IP parameters and operating mode of the Cordless Gateway. These options are described in detail below. In addition, refer to the section entitled, Configuration Examples, to help you determine what configura-

tion changes, if any, are required for your network devices. Configuring the Topology Parameter The Cordless Gateway performs two important networking functions:

Network Address Translation (NAT) and Transparent Bridging. NAT allows the Cordless Gateway to share a high-speed Internet connection with its cordless clients using a single IP Address assigned by the ISP. Transparent Bridging allows Symphony-enabled cordless computers to communicate with wired Ethernet computers as if all devices, wired and cordless, were attached to the same physical network. In reality, the Sym-

phony Cordless Network and the wired Ethernet network use two different methods to communicate: one sends messages over a cable and the other sends messages over radio waves. However, when the Cordless Gateway is connected to both networks and is operating in Transparent Bridging mode, all devices, wired and cordless, appear to be on the same Local Area Network

(LAN). This allows devices to share network resources, such as files or printers, with one another. The Cordless Gateway acts as the intermediary between the two networks. When performing NAT, the Cordless Gateway also acts as an intermediary between networks, but the two networks will not appear to be on the same LAN. Therefore, a computer on one network will not have direct access to the shared files or printer of a computer on the second network. When performing NAT, a Cordless Gateway uses two IP Addresses: one address assigned by the ISP to communicate with the Internet and one to communi-

cate with the Symphony-enabled client computers. For information on the IP 47 Address that the Cordless Gateway uses to communicate with the Internet or an Ethernet network, see the section entitled Configuring the ISP TCP/IP Settings. For information on the IP Address that the Cordless Gateway uses to communicate with Symphony clients, see the section entitled Configur-

ing the Internal TCP/IP Settings. The Cordless Gateway may be configured for two modes of operation: NAT and Transparent Bridging. In addition, by default, the Cordless Gateway is configured to perform both tasks simultaneously. This default setting should work for many network configurations, but it may be changed within the Symphony Maestro Configuration Tool. Click the <Configure> button under the Symphony-HRF Cordless Gateway heading and choose the Topology tab to change the devices operating mode. In the screen shot above, the first option refers to NAT mode only, the second option refers to Transparent Bridging mode only, and the third option, which is the default setting, corresponds to using both modes simultaneously. 48 Most networks will use option 3, the default setting, that allows the Cordless Gateway to perform both NAT and Transparent Bridging. However, if your network requires that the Cordless Gateway not perform NAT, you will want to reconfigure the Cordless Gateway to use option 2. Refer to the section entitled Configuration Examples for assistance in determining what configuration changes, if any, are required for your network devices. Configuring the ISP TCP/IP Settings The Symphony-HRF Cordless Gateway performs a function known as Network Address Translation (or NAT) in order to allow multiple Symphony-

enabled computers simultaneous access to the same high-speed Internet connection. This function requires that the Cordless Gateway be assigned an IP Address obtained from your ISP. The Cordless Gateway is configured to accept a dynamic IP Address assign-

ment from a DHCP (Dynamic Host Configuration Protocol) server by default. If your ISP uses DHCP to assign dynamic IP information and you do not have an existing wired Ethernet network in your home, then you do not need to change the configuration of the Cordless Gateway. However, if your ISP has assigned you a fixed or static IP Address, then you will need to configure the Cordless Gateway to use this TCP/IP information. To configure the Cordless Gateways ISP TCP/IP settings, open the Sym-

phony Maestro Configuration Tool on one of the Symphony-enabled computers acting as a Cordless Gateway client. Select the ISP TCP/IP tab within the Cordless Gateway Configuration screen, as shown below. Note that this information is not applicable when the Cordless Gateway is operat-

ing in Transparent Bridging mode. 49 As described above, the Cordless Gateway is configured to use DHCP by default. In addition, some ISPs assign Computer or Host Names to validate your identity before assigning a dynamic IP Address. If your ISP has as-

signed you a Computer or Host Name, enter this name in the Host Name field. Note:

If your ISP uses a Host Name for authentication purposes, the Cordless Gateway will receive an IP Address from the ISPs DHCP server only after you configure the Host Name parameter. If your ISP has assigned you a static IP Address and DNS (Domain Name Service) server addresses, click the Disable DHCP option and enter the TCP/IP information obtained from your ISP in the appropriate fields. In the example below, the Cordless Gateway has been assigned an IP Address of 204.102.51.25 with a Subnet Mask of 255.255.255.0. The default gateway is 204.102.51.254, and two DNS server addresses have been specified: 207.212.120.75 and 207.212.81.82. 50 Click <OK> to save these changes. The Cordless Gateway will be rebooted in order for these configuration changes to take effect. If you do not know if your ISP uses a DHCP server to assign addresses, open the Maestro Configuration Tool once the Symphony software has been successfully installed on a Cordless Gateway client. Click the <Status>

button under the Symphony-HRF Cordless Gateway heading to view the Cordless Gateway Status screen. If the Cordless Gateway was assigned an IP Address by a DHCP server on your network or by a server on the ISPs network, then this address will appear in the Cordless Gateway Status screen. If the Cordless Gateway was not assigned an IP Address by a DHCP server, it will report that DHCP was unsuccessful, as shown below. 51 Note:

The Cordless Gateway must be connected to the wired network or to a device that provides high-speed Internet access (e.g., a cable modem) during its boot-up cycle in order to obtain an IP Address from a DHCP server. If you believe that the Cordless Gateway should have received an IP Address from a DHCP server but did not, try recycling power to the unit. Configuring the Internal TCP/IP Settings When configured to operate in NAT mode, the Cordless Gateway acts as a DHCP server for Symphony-enabled computers on the network. By default, a Cordless Gateway client is configured to accept a dynamic IP Address from a DHCP server during the Symphony software installation. In addition, the Cordless Gateway is assigned an IP Address that it uses to communicate with the nodes on the cordless network. By default, the Cordless Gateway is assigned an IP Address of 169.254.0.1 and a Subnet Mask of 255.255.0.0. In addition, the Cordless Gateway can assign Symphony-enabled computers IP Addresses within the range 169.254.0.100 to 169.254.0.125, as shown below. 52 If this IP Addressing scheme is the same as what is used by your ISP, then you may change the IP Address of the Cordless Gateway and the range of ad-

dresses it may assign from within the Advanced tab of the Cordless Gateway Configuration screen. Note that the Cordless Gateway will not act as a DHCP server when configured to operate in Transparent Bridging mode only. Note:

Proxim recommends that only advanced users who are familiar with the TCP/IP protocol change the Cordless Gateways Inter-

nal TCP/IP Settings. Cordless Gateway Client Configuration By default, the installation of a Symphony Adapter will add several network-

ing components to a computers Network Configuration, including Client for Microsoft Networks, the TCP/IP protocol, and File and Printer Sharing for Microsoft Networks, if not already present. The installation procedure will 53 also assign the computer the workgroup designation of WORKGROUP. If the computer already has an existing workgroup name, this name will be overwritten and saved in the Original Network Profile. During installation, each Symphony Card is configured to accept an IP Address assignment from the Cordless Gateway, which acts as a DHCP server. For more information about this, refer to the section entitled Configuring the Internal TCP/IP Settings. To find out what address has been assigned, select the Run option under the Start Menu and type WINIPCFG in the field labeled Open. This will launch the Windows IP Configuration tool. In the example below, the Symphony Adapter has been assigned an IP Address of 169.254.0.103 with a Subnet Mask of 255.255.0.0. All Sym-

phony Cards will be automatically assigned a Subnet Mask of 255.255.0.0. In addition, each Symphony Card is assigned a default Gateway of 169.254.0.1 and a DNS Server address of 169.254.0.1. 169.254.0.1 is the Cordless Gateways default IP Address that it uses to communicate with Symphony clients when performing NAT. These settings allow the comput-

ers on the Symphony Cordless Network to simultaneously access the Internet via a Cordless Gateway configured to perform NAT. For most networks, you should not need to change the TCP/IP parameters for the Symphony Adapters. However, some network configurations, discussed below, require that you change both the IP Addresses of the Symphony Adapters and the operating mode of the Cordless Gateway. 54 Configuration Examples The following examples provide configuration information for a number of different network architectures supported by the Symphony-HRF Cordless Gateway. Refer to the heading below that corresponds to the type of network you have installed for configuration instructions. A Cordless Gateway Connected Directly to a Device That Provides High-Speed Internet Access If you have a device which provides high-speed Internet access, such as an ISDN router, external cable modem, or external xDSL modem, connected directly to a Symphony-HRF Cordless Gateway, then the network should consist of a number of computers each with a Symphony Adapter installed and a Cordless Gateway connected to the high-speed Internet device. In this configuration, the following changes are required:

Changes to Cordless Gateways Topology Parameter. No change is required to this parameter. However, changing the Cordless Gateway mode so that it performs NAT only (instead of both NAT and Transparent Bridging) will not adversely affect network operation. Changes to Cordless Gateways TCP/IP Parameters. If your ISP uses DHCP to assign IP Addresses, then no changes to the configuration are necessary. However, if your ISP has assigned you static TCP/IP information

(IP Address, Subnet Mask, default Gateway, and DNS Server addresses), then you need to configure the Cordless Gateways ISP TCP/IP parameters as described in the Configuring the ISP TCP/IP Settings section earlier in this chapter. Changes to Cordless Gateway Clients. No change is required for computers that have a Symphony Adapter installed. 55 A Cordless Gateway Connected to a Wired Network That Does Not Have Shared Internet Access If the Cordless Gateway connects to a hub on an existing wired network which does not have shared Internet access, then the network should consist of a number of computers each with a Symphony Adapter installed and a Cordless Gateway connected to either a hub with no more than 8 Ethernet devices attached or to a single stand-alone Ethernet-ready computer. In this configuration, the following changes are required:

Changes to Cordless Gateways Topology Parameter. Configure the Cordless Gateway so that it performs Transparent Bridging only. Changes to Cordless Gateways TCP/IP Parameters. There are no changes required for these parameters. Changes to Cordless Gateway Clients. In order for Ethernet-ready comput-

ers and Symphony-enabled computers to communicate as part of the same LAN, you must configure all devices (Ethernet and Symphony) to use the same IP network. Since the Cordless Gateway does not act as a DHCP server when in Transparent Bridging mode, you must reconfigure the Symphony-

enabled computers with static IP Addresses that match the settings of the Ethernet computers (the TCP/IP settings are located within the Control Panels Network icon on each computer). Alternatively, if you have a DHCP server already on your network, then no additional configuration is necessary as Symphony-enabled computers should receive an address assignment from the networks DHCP server. Note that once you reconfigure the Cordless Gateway to use Transparent Bridging mode only, you may need to release the Symphony clients existing IP Addresses using the Windows IP Configu-

ration tool or by restarting the Symphony clients in order for the computers to receive a new IP Address assignment. Keep in mind that the Symphony Adapter acts like a standard Ethernet card once installed. The Symphony Adapter can use any existing IP Address scheme already in use by Ethernet devices and can also be configured to use any additional networking protocols, such as NetBEUI or IPX/SPX, already installed on the network. 56 A Cordless Gateway Connected to a Wired Network That Has Shared Internet Access If the Cordless Gateway connects to a hub on an existing wired network which has shared Internet access, then the network should consist of a number of computers each with a Symphony Adapter installed and a Cordless Gateway connected to a hub with no more than 8 Ethernet devices attached. A device that provides high speed Internet access, such as an ISDN router, cable modem, or xDSL modem, is also connected to the hub or is acting as the hub. In this scenario, the configuration of the Symphony products is highly dependent upon the specific design of your network. For example, if the high-speed device on the network is a DHCP server or if your ISP uses DHCP, you will want to configure the Cordless Gateway to operate only in Transpar-

ent Bridging mode. This will allow all computers (Ethernet and Symphony) to be on the same LAN and share files and printers while having simulta-

neous access to the Internet. Alternatively, if you need the Cordless Gateway to perform NAT due to a limited number of IP Addresses assigned by the ISP, then the Cordless Gateway needs to perform both Transparent Bridging and NAT, and the Symphony Adapters need to retain the dynamic IP Address assignments that they receive from the Cordless Gateway. In this case, the computers on the Symphony Cordless Network will have a different IP Address scheme (using addresses in the 169.254.0.0 network) than the computers on the Ethernet

(using IP Addresses assigned to you by the ISP). Therefore, you need to install another networking protocol, such as NetBEUI, in order for the Ethernet and Symphony computers to appear on the same Local Area Network (LAN) and to share files and printers. Given the above, Proxim presents the following guidelines for using the Symphony products in this network configuration:

Changes to Cordless Gateways Topology Parameter. If you have a DHCP server on the network and you want the Symphony-enabled computers to receive a dynamic IP Address assignment from the network, then configure the Cordless Gateway to operate in Transparent Bridging mode only. If you do not have a DHCP server on the network but have available static IP Addresses that you can assign to the Symphony-enabled computers, then configure the Cordless Gateway to operate in Transparent Bridging mode only. If you do not have a DHCP server on the network and do not have 57 enough unique IP Addresses for all of the Symphony-enabled computers, leave the Cordless Gateway at the default setting to allow both NAT and Transparent Bridging. When configured to the default topology setting, the Cordless Gateway will also act as a DHCP server for the Symphony clients. Changes to Cordless Gateways TCP/IP Parameters. If you configured the Cordless Gateway to operate in Transparent Bridging mode or your network has DHCP (from the ISP, a network server, or the high-speed Internet device), then you do not need to change these parameters. However, if the ISP has assigned you a limited number of static IP Addresses, then configure the Cordless Gateway to use one of these addresses and enter the additional TCP/

IP information (Subnet Mask, default gateway, and DNS server addresses) in the appropriate fields in the ISP TCP/IP tab. Changes to Cordless Gateway Clients. If you have a DHCP server on the network and have configured the Cordless Gateway to operate in Transparent Bridging mode only, then there is no need to reconfigure the Cordless Gateway clients since they will automatically receive an address assignment from the networks DHCP server. Note that once you change the Cordless Gateway to use Transparent Bridging mode only, you may need to release the Symphony clients existing IP Addresses using the Windows IP Configu-

ration tool or restart the Symphony clients in order for the computers to receive a new IP Address assignment. If you do not have a DHCP server on the network but have configured the Cordless Gateway to operate in Transparent Bridging mode only, then you need to manually assign each Symphony-enabled computer an IP Address, a Subnet Mask, a default Gateway, and DNS Server information that is valid on your network. If you do not have a DHCP server and have configured the Cordless Gateway with an IP Address obtained from the ISP, each Symphony Adapter should retain the dynamic IP Address assignments that they receive from the Cordless Gateway and you should configure all of your computers (both Ethernet and Symphony) to use a second networking protocol, such as NetBEUI or IPX/SPX, to allow them to share files and printers and appear to be a part of the same LAN. 58 A Cordless Gateway Connected to a Network With a Server If the Cordless Gateway connects either to an existing network containing a network server or directly to a server, refer to the section entitled A Cordless Gateway Connected to a Wired Network That Does Not Have Shared Internet Access for configuration information. In addition, if the server has access to the Internet, it may be possible to install a third-party proxy software program so that it can allow the other computers on the network to share this Internet connection. Contact your local computer retailer to find out what software packages are available that perform this proxy function. File Sharing During installation, the Symphony Composer Installation Wizard generates a list of available drives which the computer may share with the network. The list of drives includes not only hard drives, but also any floppy disk drives, CD-ROM drives, and Iomega Zip drives that the Composer finds on the computer. The Symphony Composer Installation Wizard then prompts you to place a check mark next to each drive you want to share with the network and select an access level (Read/Write or Read Only). After the Symphony Composer Installation Wizard completes the configura-

tion of the Symphony software, the drives you specified will be available to other users on the network. At any time, you may change which drives are shared from within the Symphony Maestro Configuration Tool by clicking the <Configure> button below the Symphony Network Status heading and choosing the File Sharing tab. The Symphony Maestro Configuration Tool also allows you to select specific directories for sharing so that you do not have to give access to an entire drive. Therefore, you can limit the amount of information that is available over the network. If you only want to provide access to a specific set of files contained in the same directory, then you can choose to share only that directory. In the example below, only the folder labeled DOS on the C: drive is shared with the rest of the network. 59 In addition, you may also change the access level (Read/Write or Read Only) provided to remote users. Read/Write access allows a remote user to view, copy, create, and delete files on the shared drive. Read Only access allows a remote use to view and copy files on the shared drive. This feature allows you to determine what information is made generally available to the rest of the network and what information should reside only on the local computer. After you select a folder or drive to share, the Maestro tool will prompt you to choose the type of access remote users will have to the shared resource, as shown below. 60 By default, Maestro will grant remote users Read/Write access to the shared resource. If you want to allow this type of access to remote users but prohibit unauthorized access, enter a password in the field labeled Read/Write Password and click <OK>. If you want to grant Read Only access to remote users, select the Read Only Access entry. You may also set a Read Only Password to prevent unauthorized access. Finally, if you select Depends on Password, you may set two different passwords, one for Read/Write access and the other for Read Only access, to allow full access to some users and partial access to others. At any time, you can reset the access options for a particular drive or folder by highlighting its entry in the Select Directories to share list and clicking the <Properties> button. Warning!

Proxim recommends that you establish passwords for each drive that you share on the local area network. Depending on the type of Internet connection you have, others may be able to see your computers in their Network Neighborhood and have unautho-

rized access to your drives. Once you have determined which drives or directories to share with other users, you now need a method to access these shared files from remote computers. The Symphony Maestro Configuration Tool includes a feature called Remote Drive Sharing that provides a computer with access to shared files over the network. This feature is described below. 61 Remote Drive Sharing From within the Symphony Maestro Configuration Tool, you can assign a remote drive a drive letter on the local computer. For example, the C: drive of a remote computer may be assigned to the I: drive of the local computer. Once this remote drive share has been established, the remote drive will appear to be another drive in the local computers My Computer icon, as shown in the following screen shot:

This process is also called mapping a network drive. A mapped network drive automatically reestablishes the connection each time the computer is restarted. You can establish drive letters for not only remote shared drives, but also for remote shared directories. To create a remote drive share, open the Symphony Maestro Configuration Tool and refer to the Symphony Network Map, as shown below. 62 Highlight the name of the remote computer to which you want to attach and click the <Select> button (alternatively, you may simply double-click the name of the remote computer). In the example above, the local computer is called Moms computer and the remote computer is called Kids com-

puter. Next, click the Remote Drive Sharing tab at the top of the screen to view a list of shared drives or directories on the remote computer, as shown below. 63 Highlight the name of a remote shared resource and click the <Attach to Share> button. The following dialog box will appear:

64 From within this screen, you may choose the drive letter on the local com-

puter to assign to the shared resource using the drop-down menu. In the example above, the C: drive on the computer named Kids computer is mapped to the local computers I: drive. Click <OK> once you have selected the desired drive letter. The mapped drive letter should now appear to the left of the remote drive in the list of shared resources, as shown below. Once the remote drive is established, you may view the contents of the shared drive or directory by double-clicking the appropriate drive letter in the My Computer icon, located on the Windows desktop; the remote share will appear to be another drive on the computer. In the future, if you want to disconnect a shared drive mapping, highlight the name of the remote shared resource in the Remote Drive Sharing screen and click the <Detach From Share> button. 65 Printer Sharing The Symphony Cordless Network utilizes the built-in printer sharing capabilities of Windows 95 and 98. Figure 7, below, shows a Symphony Cordless Network consisting of a laptop and a desktop computer that has a printer attached. The laptop can print documents to the desktops printer over the Symphony Cordless Network. Symphony Cordless Network Sharing a Printer Figure 7 During installation, the Symphony Composer Installation Wizard generates a list of available printers which the computer may share with the network. Place a check mark next to each printer that you want to share. You may also change your shared printers selection at any time from within the Symphony Maestro Configuration Tool. Once the Symphony installation is complete, the network computers will be ready to share printers. Follow these instructions to install a remote printer:

Logon to the Network. Each time you restart a network computer, 1. you will be prompted to provide a Microsoft Networking User name and Password to logon to the network, as shown below. 66 Enter your Password and click <OK> to enable the computers network functions. Do NOT click the <Cancel> button. Note:

You must enter a User name and Password to log onto the network. If you choose <Cancel>, you will be unable to access network resources. 2. Go to the Network Neighborhood icon. After two or more comput-

ers have logged onto the network, double-click the Network Neighborhood icon on the Windows desktop to see what shared printers are available. In the example below, the remote computer, named Kids computer, is sharing a printer called printer. Double-click to Begin the Installation. Double-click the shared 3. printers Network Neighborhood entry to begin the installation of the remote printer. If this printer has not been installed previously, the following dialog box will appear:

67 4. Run the Add Printer Wizard. Click the <Yes> button to proceed with the installation. This will launch the Add Printer Wizard, shown below. Follow the on-screen instructions to complete the installation of the printer. Also, you should have the printers installation CD or diskette(s) available during the installation. You may be prompted to insert the CD or diskette(s) if Windows cannot find the appropriate driver files. Confirm that the Printer Has Been Successfully Installed. After 5. the printer has been successfully installed, go to the Control Panel and click the Printers icon to confirm that the printer has been added to the list of available printers, as shown in the example below. 68 Once you have confirmed that the printer is installed, it is ready for use. Simply select the network printer from the drop-down list within each applications Print screen, as shown below. If you are having difficulty printing to a network printer, refer to Chapter 12 and the Symphony Web site for troubleshooting suggestions. Also, refer to the printers documentation to determine if any additional steps are required by the manufacturer in order to share this printer on a network. 69 8. Symphony Network Switcher The installation procedure will automatically configure a Symphony Adapter with all of the parameters required to establish network communication. However, under some circumstances, you may want to move a computer from the cordless network to another network. For example, you may want to connect the computer to your office LAN (Local Area Network) that is in a different location and uses a non-Symphony network card, such as a wired Ethernet card or a Proxim RangeLAN2 Card, to achieve network access. Alternatively, you may want to dial into the office LAN from home. In either case, the Symphony Network settings may conflict with the settings of this other network. Normally, in order to transport a computer from one network to another, you must manually change several network settings each time the computer is relocated. This process can be tedious and error prone. However, the Symphony software eliminates this concern by creating two Network Profiles that contain the settings for each network. During installation, the Symphony Composer Installation Wizard saves your computers existing network configuration into a Network Profile called Original. The Symphony Composer then reconfigures the network settings so that the computer will communicate with the cordless network. These new network settings are saved in a Network Profile called Symphony. Once the installation is complete, the computer will use the Symphony Network Profile until you switch back to the Original Network Profile using the Symphony Network Switcher. Note:

Among the network information saved within a Network Profile is a computers Internet Proxy Settings. If you have configured Netscape Navigator with Proxy information, these settings are not saved within a Network Profile. Netscape Navigator uses its own Internet Proxy information that the Symphony Composer Installation Wizard cannot access. If you have configured Netscape Navigator with Internet Proxy Settings, you must change this information manually from within Netscape Navi-

gator each time the computer is relocated. After the Symphony Composer Installation Wizard has completed the configuration of a Symphony Adapter, the computer may automatically launch the Network Switcher program (depending on the computers con-

figuration), and the Network Switcher icon may appear in the Windows 70 System Tray, as shown below. If the icon does not appear, the Network Switcher program and icon can be launched from the Symphony section of the Start Menus Programs group. Network Switcher icon If you move the Windows cursor over the Switcher icon, a dialog box will appear that reports the current profile in use, as shown below. Depending on your computers configuration, this icon may appear in the Windows System Tray each time you restart the computer. You can prevent-

ing this icon from appearing in the System Tray by unchecking the box labeled Always show Switcher icon in taskbar within the Network Switcher configuration screen. If this icon does not appear automatically, you can enable this feature by checking the box labeled Always show Switcher icon in taskbar within the Network Switcher configuration screen. In addition to the Switcher icon, the Network Switcher program may also create a DOS prompt at boot-up that allows you to select which network profile you want to use, as shown below. This prompt will appear before Windows loads each time you restart the computer if you chose to enable this option when prompted by the Composer wizard during installation. Windows will not load until you select a network profile and press <Enter>. You can disable this feature by unchecking the 71 box labeled Always prompt user at startup within the Switcher configura-

tion screen. If this prompt does not appear automatically and you want to utilize this feature, please a check mark next to the box labeled Always prompt user at startup within the Switcher configuration screen. At any time, you may edit an existing Network Profile or create a new one using the Network Switcher configuration screen. Simply double-click the Switcher icon to display the Network Switcher configuration screen, shown below. Alternatively, you can right-click the Switcher icon and choose Edit or select the Symphony Network Switcher entry found in the Symphony section of the Start Menus Programs group to display this screen. Switching Between Network Profiles The Network Switcher offers three ways to toggle between Network Profiles. The first method is to right-click the Switcher icon in the Windows System Tray and select the Switch option from the pop-up menu to choose between Network Profiles, as shown below. 72 The second method is to select a network profile when prompted during boot-up, as shown above. The third method is to launch the Switcher configuration screen and select a profile from the Switch to Profile dialog box, as shown below. Click <Switch> to change the network profile. Restart the computer when prompted. If you choose not to restart the computer when prompted, the profile listed in the Active Profile on next Reboot field will change to indicate that the new profile will be used following the next restart. Note that the computer will need to be restarted each time you change the Network Profile. This step is necessary in order to initialize the computers network functionality with the new settings. Editing a Network Profile The configuration screen displays information about the current profile and the switcher settings. To edit the network settings associated with a particu-

lar Network Profile, select the profile from the Switch to Profile drop-down menu and click <Edit Profile ...>. This displays the Switchers Edit Profile screen, as shown below. 73 Select one of the headings on the left-hand side to view and edit a profiles parameters. The Identification settings option, shown above, configures the name, workgroup designation, and description that the computer will use when operating in the selected profile. The Cordless settings option, shown below, configures a Profiles Symphony Cordless Network parameters. Select either the Station Settings or Master Settings tab to view additional advanced settings. For more information on these advanced cordless parameters, refer to Appendix D. Note that the Domain and Roaming parameters are grayed out in the Symphony Profile. Symphony products do not support these RangeLAN2 parameters. In the example below, a Symphony Conductor computer is using the word peer as the Security Code and it is configured as a Master device. The user configured this Security Code using the Composer Installation Wizard. Proxims RangeLAN2 Cards use a parameter called Security ID, which is similar to a Symphony Cards Security Code, except the Security ID is stored on the RangeLAN2 Card itself and cannot be read or retrieved, only overwrit-

ten. RangeLAN2 users who transport a laptop between a RangeLAN2 74 network and a Symphony network should configure the Original Profile to use the Security Code (or Security ID) that resides within the card rather than a configured Security Code to communicate with a RangeLAN2 network. The TCP/IP settings option configures the TCP/IP parameters that the computer will use when operating in the selected profile. The TCP/IP parameters include IP Address, Subnet Mask, DNS configuration, Gateways configuration, Proxy Server settings, and WINS configuration. If you are unfamiliar with these settings, Proxim recommends that you leave these parameters at their default value. The IPX/SPX settings option configures the values that a computer with the IPX/SPX protocol installed will use when operating in the selected profile. If you are unfamiliar with these settings, Proxim recommends that you leave these parameters at their default value. The File/Printer Sharing settings option configures the drive mappings and default printer that the computer will use when operating in the selected profile, as shown below. 75 The File/Printer Sharing settings screen allows you to create, delete, or edit drive mappings (also known as remote drive shares) used by the computer when configured to operate in the selected profile. To make a new drive share, click <Create Map> and assign a drive letter and network path. To delete or edit an existing drive mapping, highlight one of the entries in the Drive Mapping table and click the appropriate button. To change a profiles default printer, select another installed printer from the Default Printer drop-down menu. The Miscellaneous settings option determines which Proxim programs are automatically launched when a computer is restarted using the selected profile. Maestro.exe corresponds to the Symphony Maestro Configuration Tool. Statmon.exe corresponds to the RangeLAN2 Status Monitor. For the Symphony Profile, you want the Symphony Maestro Configuration Tool to be launched automatically but not the RangeLAN2 Status Monitor, so the Maestro.exe entry should have a check mark and the Statmon.exe entry should not, as shown below. 76 For a profile that communicates with a RangeLAN2 network, you want the RangeLAN2 Status Monitor to be launched automatically but not the Maestro Configuration Tool, so the Statmon.exe entry should have a check mark and the Maestro.exe entry should not. For a profile that does not communicate with either a RangeLAN2 or Symphony network (such as a profile that uses a wired Ethernet card), then neither the Maestro.exe entry nor the Statmon.exe entry should have a check mark so that these programs will not be launched automatically. After you have made changes to a profiles network settings, click the <Save Changes> button. You will be prompted to restart the computer in order for the change to take effect. To exit the Edit Profile screen without making any changes, click the X box in the upper right hand corner of the screen. Creating and Deleting Network Profiles Within the Network Switcher configuration screen, you may create a new Network Profile or delete an existing one. 77 To create a new profile, click <Create Profile>. This will make a copy of an existing profile and prompt you to assign the duplicate profile a new name, as shown below. Once you have created a new profile, you may change its settings using the Edit Profile options discussed earlier this chapter. There is no limit to the number of Network Profiles that you can create. To delete a profile, click <Delete Profile> and select a profile from the drop-

down menu, as shown below. Click <OK> to delete the profile. Examples of When to Use Network Profiles Here are a few examples of when it may be necessary to switch between Network Profiles:

78 Transporting a Laptop Computer From the Home to the Office. Shut down the computer and eject the Symphony PC Card from the PCMCIA slot and take the computer to the office. Insert your office network card or place the computer in its docking station, if it has one. Turn on the computer and select the Original Profile (or another Profile you have created specifi-

cally for the office) at the Switcher DOS prompt. The Network Switcher will restore all of your office LANs settings during boot-up and the laptop will be ready to communicate with the office LAN without further configuration. Alternatively, you can change the Network Profile setting by right-clicking the Network Switcher icon or by clicking the <Switch> button in the Switcher configuration screen and restarting the computer when prompted. Transporting a Laptop Computer From the Office to the Home. At the end of the day, shut down the computer and remove the office network card from the PCMCIA slot. Take the laptop home and insert the Symphony PC Card into the PCMCIA socket. Turn on the computer and select the Symphony Profile at the Switcher DOS prompt. The Network Switcher will restore all of the Symphony settings during boot-up and the laptop will be ready to communicate with the cordless network without further configura-

tion. Alternatively, you can change the Network Profile setting by right-

clicking the Switcher icon or by clicking the <Switch> button in the Switcher configuration screen and restarting the computer when prompted. Transporting a Laptop Computer Between a RangeLAN2 Network and a Symphony Network. Follow the instructions in Appendix B to install the Symphony software on a laptop that already has a RangeLAN2 Card installed and configured. After the Symphony software has been installed, the laptop will be set to the Symphony Network Profile and will communicate with the Symphony Cordless Network. To revert back to the RangeLAN2 settings, simply change the Network Profile from Symphony to Original using one of the three switching techniques. The Network Switcher will restore all of the RangeLAN2 settings, and the computer will be ready to communicate with the RangeLAN2 network without any additional configuration. To reestablish communication with the Symphony Cordless Network, simply change the Network Profile back to Symphony using one of the three switching techniques and restart if prompted. After the laptop restarts or completes it boot-up process, it will communicate with the Symphony Cordless Network. Note:

If you intend to install Symphony software on a computer that already has a RangeLAN2 Card installed, refer to Appendix B for specific installation instructions. 79 q q q q q q q q q q q q q q q 9. Adding a New Product to a Symphony Cordless Network In the future, if you decide to increase the number of computers on the cordless network or decide to add a Symphony Cordless Gateway to an existing network, you may need to reconfigure the computers on the cordless network. Below are some guidelines for reconfiguring the Symphony Cordless Network. Note:

There can be only one shared device (modem, Ethernet card, or Cordless Gateway) in a Symphony Cordless Network. Adding a New Computer to a Cordless Network If you are adding a new computer to an existing cordless network with a Symphony-HRF Cordless Gateway, then simply follow the installation instructions in Chapters 3, 4, and 5 to configure this new addition to the cordless network. Adding a Symphony-HRF Cordless Gateway to a Cordless Network If you have an existing cordless network to which you want to add the Symphony-HRF Cordless Gateway, follow these steps:

1. Shut down all computers on the cordless network. 2. Install the Symphony-HRF Cordless Gateway. The installation procedure for the Cordless Gateway is described in Chapter 3 of this manual. 3. Turn on one of the computers on the cordless network. Rerun the Sym-

phony Composer Installation Wizard from the Symphony folder of the Start Menus Programs group.

Right-click the Symphony icon in the System Tray and choose About to confirm that the software revision number has changed. 85 11. Uninstalling Symphony Software Proxim provides an uninstall tool to facilitate the removal of the Symphony Adapter from a desktop or notebook computer. The Symphony installation procedure copies the file UNINSTAL.EXE to the computers hard drive and places a Windows shortcut in the Symphony folder within the Programs section of the Start Menu. To begin the uninstall procedure, go to the Start Menu and choose Uninstall from the Programs groups Symphony folder, or go to the Add/

Remove Programs icon in the Control Panel and remove the Symphony Cordless Network entry. When prompted, click <OK> to confirm that you want to uninstall the Symphony software, as shown below. Next, you will be prompted to exit from all Windows programs before proceeding, as shown below. Close all Windows programs and then click <OK> to continue. Please wait while the Uninstall program removes the Symphony components from your computer. Click <OK> when the process is complete, as shown below. When prompted, shut down the computer and remove the Symphony Adapter. 86 Also, note that the Uninstall program will reconfigure the computer with the pre-Symphony network settings stored in the Original Profile, if any exist. For more information on Network Profiles, refer to Chapter 8. If you decide to reinstall the Symphony Adapter at a later date, first turn off the computer and insert the card into the appropriate PCMCIA, ISA, or PCI slot or USB port, as described in Chapter 3. Then, turn on the computer. Windows 98 or Windows 95 will automatically detect the card as a new device and run either the Add New Hardware Wizard or the Update Device Driver Wizard, depending on which version of Windows is installed. Follow the installation steps described in Chapters 4 and 5 to install of the Sym-

phony Adapter. To uninstall the Symphony-HRF Cordless Gateway, unplug it from the wall and disconnect the Ethernet cable. 87 12. Troubleshooting The Symphony Cordless Networking Suite of products is designed to be very easy to operate. If you do experience difficulties, however, use the informa-

tion in this chapter and on Proxims Symphony Web site to help diagnose and solve your problems. Refer to Chapters 4 and 12 of the Symphony Adapters Users Manual for assistance with problems that arise during the installation of a Symphony Adapter. If you cannot resolve a problem, contact Symphony Technical Support, as described in Appendix E, How to Reach Technical Support. Frequently Asked Technical Support Questions Operational Issues Problem/Symptom Question Possible Solution/Answer Chapter in User's Manual 7 7 I can share files and printers between the computers on the Symphony Cordless Network, but I can't access the Internet through my high-speed Internet connection. All of the computers on the Symphony Cordless Network and the computers on the Ethernet network have access to the Internet. However, I cannot share resources between Symphony and Ethernet computers. Confirm that you have configured the Ethernet Bridge with an IP address assigned to you by the ISP. If your ISP uses DHCP to assign addresses, click the <Status>

button under the Symphony Ethernet Bridge heading in the Maestro Configuration Tool to confirm that the Ethernet Bridge has successfully received an address assignment. If the Ethernet Bridge is configured to perform NAT so that the Internet connection can be shared with the Symphony Cordless Network, then the Symphony Cards have an IP address in the 169.254.0.0 network. In order to have access to the Internet, the Ethernet cards probably use a different IP addressing scheme. Try installing another networking protocol, like NetBEUI, to allow the Symphony and Ethernet computers to share resources. 88 Problem/Symptom Question Possible Solution/Answer Chapter in User's Manual I can't print to the network printer. I get an error message while trying to copy driver files during the installation of my printer. The Ethernet Bridge Networking icon in the Windows System Tray is red. Why?

The Status LED on the top of the Ethernet Bridge has turned red. 1. Confirm that you have successfully installed the network printer on the computer from which you want to print. 2. Confirm that the printer and the computer it is attached to are powered on. 3. Confirm that the computer with the printer and the computer from which you want to print are both successfully logged into the network. 4. Test the strength of the link between the two computers from within the Maestro tool. The computers may be out of range of one another. Certain printer manufacturers require that network computers run a proprietary software program to use the printer over the network. Consult your printer documentation for more information on how to share the printer on the network. The Ethernet Bridge icon will turn red when the computer cannot communicate with the Ethernet Bridge. Try these steps:

1. Confirm that the Ethernet Bridge is powered on. 2. You may be out of range of the Ethernet Bridge. Try moving the computer closer to it. 3. Confirm that the Security Code has not been changed for the Symphony Card from within the Maestro Configuration Tool. Unplug the Ethernet Bridge's power adapter from the wall outlet. Wait 10 seconds and plug it back into the wall. If the LED remains red, contact Technical Support. 89 7 7 6 3 Chapter in User's Manual 2, Appendix A 3, Appendix A 6, 7 Problem/Symptom Question Possible Solution/Answer What type of 10BaseT cable should I use to connect the Ethernet Bridge to a cable modem?

The Link LED on the back of the Ethernet Bridge is not illuminated. I can't find another computer on the cordless network. In general, a 10BaseT port on an ISDN router, a cable modem, or xDSL modem will have a pinout similar to a cabling hub. In this case, use the crossover cable provided in the product package to connect the Ethernet Bridge to one of these devices. However, if the 10BaseT Link LED does not illuminate on both ends, check the documentation for your cable modem to confirm its pinout. If this information is unavailable, try using a standard 10BaseT cable. Confirm that the appropriate 10BaseT cable is properly connected to both the Ethernet Bridge and the attached device. For example, if you are connecting to a hub, use the cross-over cable shipped with the unit. If you are connecting to a stand-alone computer, use a standard 10BaseT cable. 1. Confirm that the other computer is listed in the Symphony Network Map in the Maestro tool. 2. Test the strength of the link between the two computers from within the Maestro tool. The computers may be too far apart. 3. Confirm that you successfully logged onto the network. If you are unsure, go to Shut Down in the Start Menu and choose "Close all programs and log on as a different user" to bring up the Network Logon prompt. 4. Use Microsoft's Find Computer utility to locate the computer on the network. 90 General Questions Problem/Symptom Question Possible Solution/Answer Chapter in User's Manual Can I run an application from a remote computer over the cordless network?

This will depend on whether or not the application is designed to be used over a network. Consult the application's user guide to determine if it supports operation over a network. Yes, as long as the game supports multiple players over a LAN (local area network). Refer to the game's user guide for more information. Yes, if your scanner supports operation over a network. Contact the scanner's manufacturer for details. No. You can only use one Ethernet Bridge on any cordless network. The Symphony Cordless Networking Suite uses frequency hopping spread spectrum technology in the 2.4GHz band to communicate. This is the same frequency band used by microwave ovens and 2.4GHz phones. Frequency hopping technology is designed to minimize interference so while you may notice a reduction in performance, your devices will not cease to function. Proxim recommends against installing the base station of the 2.4 GHz phone in between two Sympony devices. Switch between Network Profiles using the Symphony Network Switcher. See Chapter 8 for details. 91 8 Problem/Symptom Question Possible Solution/Answer Chapter in User's Manual 2 What is the maximum range I can expect to achieve using the Symphony products?

Can I have multiple E-Mail accounts from the same ISP so that multiple members of the household can access their own E-

Mail simultaneously?

Can I connect the Symphony Ethernet Bridge to my office network so that my laptop can access the network?

Can I use an Ethernet Bridge and a Symphony Cordless Modem on the same cordless network?

I have reviewed all of the troubleshooting suggestions but I still can not solve my problem. Proxim has specified that the range between two Symphony devices is up to 150 feet. Range is highly dependent upon the particular environment in which the product are used. Obstacles, such as walls and ceilings, weaken the radio signals. Metal objects, such as screen doors, windows screens, and filing cabinets, also have an adverse effect on range. Many ISPs offer multiple E-Mail accounts. Contact your ISP for more information. The Symphony Ethernet Bridge can only be connected to small hubs with no more than 8 devices attached. If your office has more than 8 Ethernet devices networked together, then you cannot use the Ethernet Bridge to provide network connectivity to a cordless laptop. No. Each cordless network can support either one Ethernet Bridge, one Cordless Modem, or one computer acting as a Symphony Conductor. These three devices cannot coexist on a Symphony network. Review the support documentation available on the Symphony Web site at http://www.proxim.com/symphony/. If you are still unable to solve the problem, call Symphony Technical Support at 800-411-8106 for technical assistance with the Symphony product line. 92 A. 10BaseT Connector Specification The 10BaseT connector located on the back panel of the Cordless Gateway is wired like a cabling hub. Standard 10BaseT specifications apply to the 10BaseT interface of the Symphony-HRF Cordless Gateway. No segment may exceed 100 meters. Use a standard 10BaseT cable to connect the Cordless Gateway directly to an Ethernet Card, to a network router, or to the chaining port of an Ethernet hub

(also called the uplink port). Use a 10BaseT crossover cable to connect the Cordless Gateway directly to a port on an Ethernet hub or to a device wired like a hub, such as an ISDN router or cable modem. A 10BaseT crossover cable is included in the product package; a standard 10BaseT cable is not included. Also, you can monitor the Link LED to determine whether or not you are using the appropriate cable. Refer to Chapter 3 for details. A crossover cable differs from a standard 10BaseT cable in that pins 1 and 3 and pins 2 and 6 are crossed. These pins control the transmission and receipt of data. Figure 7 below illustrates the pinout for a 10BaseT crossover cable. 1 2 3 4 5 6 7 8 1 2 3 4 5 6 7 8 Figure 7 10BaseT Crossover Cable Pinout 93 B. Using Symphony With RangeLAN2 Cards The Symphony product line uses a radio frequency technology similar to that used by Proxims corporate product line, RangeLAN2. Therefore, there is a degree of compatibility between RangeLAN2 Cards and Symphony products. RangeLAN2 Cards can load Symphony drivers and use Symphony software to communicate over a Symphony Cordless Network. However, Symphony Cards cannot use RangeLAN2 drivers or software. This compatibility allows customers who have a RangeLAN2 network in their office to also use RangeLAN2 Cards at home on a Symphony network. Using the Network Switcher, discussed in Chapter 8, a laptop installed with a RangeLAN2 PC Card may alternate between a RangeLAN2 network and a Symphony Cordless Network. There are a few special considerations associated with alternating between two networks using the same RangeLAN2 Card. The Network Switcher accounts for the majority of these concerns, but requires a specific installa-

tion procedure in order to configure all of the network parameters properly. Follow these steps to install the Symphony software on a computer that already communicates with a RangeLAN2 network:

1. Run SETUP.EXE from the Symphony Installation CD on a computer that already has the RangeLAN2 driver installed. The following dialog box should appear:

94 Click <Install> to continue. 2. Be patient while the Symphony Installation program installs all of the necessary operating files. The Symphony Installation screen will report when the installation has been successfully completed, as shown below. Restart the computer when prompted. 3. Windows (95 or 98) will make the final adjustments to its system to allow the Symphony Card to operate properly. Restart the computer a second time if prompted. 4. After the computer is restarted, you may be prompted to enter a network password before proceeding, as shown below. This will enable the computers network functionality. Do NOT choose the <Cancel> option. 95 Enter a network User name and Password and click the <OK> button to log onto the network. The Password may be left blank. You will be prompted to confirm your Password before continuing. 5. The Symphony Composer Installation Wizards Welcome screen will now appear. See Chapter 5 for additional information about this wizard. Among other things, it will prompt you to enter the Security Code used by the cordless network. Restart the computer if prompted. The computer should now have access to the Symphony Cordless Network and will act like any other Symphony-enabled computer on the network. To revert to the RangeLAN2 configuration, simply change the Network Profile from Symphony to Original from within the Symphony Switcher configuration screen, by right-clicking the Switcher icon in the System Tray, or by selecting the Original profile at the Switcher DOS prompt during boot-up. When you are ready to return to the Symphony Profile, simply use one of the three methods above to switch the current profile. Refer to Chapter 8 for more information on the Network Switcher and learn how to create and edit Network Profiles. 96 C. Using the Symphony Driver for Windows NT The Symphony Installation CD contains a sub-folder labeled WINNT. This folder contains the Symphony driver for Windows NT 4.0. This driver provides full networking functionality for a Windows NT computer, just like any standard Ethernet card but without the wires. Win-

dows NT computers with a Symphony Card installed can share files and printers with other network computers and participate in multi-user games over the network. A Windows NT computer can also access the Internet or communicate with a wired Ethernet network through a Symphony-HRF Cordless Gateway. There are many advanced networking features available with the Windows NT operating system; refer to the Windows NT documen-

tation for additional information on these topics. Users who have installed a Symphony Card in a Windows 95/98 computer will notice a few differences when using a card under Windows NT. First, the Symphony driver for Windows NT does not include any of the Symphony software tools that are installed with the Windows 95/98 driver, such as the Maestro Configuration Tool or Composer Installation Wizard. Also, a Windows NT computer with a Symphony Card installed will not show up in the Symphony Network Map of the network computers running Windows 95/

98 even though the card may be operational. Note:

Symphony-HRF Cordless Gateway users need at least one other computer running Windows 95 or Windows 98 on the network in order to configure and monitor the status of the Cordless Gateway since the Windows NT driver does not include the Symphony Composer and Symphony Maestro software tools. Installing the Symphony Driver for Windows NT Since Windows NT 4.0 is not a plug and play operating system, a Symphony Card will not be auto-detected when first inserted into a PCMCIA, ISA, or PCI slot. Windows NT does not provide support for USB so a Symphony USB Adapter cannot be used with this operating system. Also, since Win-

dows NT configures devices during boot-up, it is important to have the Symphony PC Card inserted in the PCMCIA slot before the computer is turned on. 97 Follow these steps to install the driver:

1. Install the Symphony PC, ISA, or PCI Card following the hardware installation instructions contained in Chapter 3. 2. Turn on the computer and logon to the operating system. When the Windows NT desktop appears, open the Network icon in the Control Panel and choose the Adapters tab, as shown below. 98 3. Click the <Add> button and choose the <Have Disk> option from the Select Network Adapter dialog box, as shown below. 4. When prompted to insert a driver disk, insert the Symphony Installation CD into the CD-ROM drive and type the path for the Windows NT driver. In the example below, the CD-ROM drive is installed as drive letter D. 99 5. The OEM Option list will appear, as shown below. Highlight the entry in the OEM Option list that corresponds to the type of Symphony Card you are installing and click <OK>. 6. If you are installing a Symphony ISA or PC Card, you will be prompted to select a Bus Type and Number. For the Symphony ISA Card, choose ISA for the Bus Type and 0 for the Number; for the Symphony PC Card, choose PCMCIA for the Bus Type and 0 for the Number. Click <OK> to continue. 100 7. When the installation is complete, the Card Setup screen will appear. All of the Symphony parameters may be configured from within this screen, which offers different configuration options for each Symphony Card. The Card Setup screen for the Symphony PC Card is shown below. The installation of the Symphony PC Card requires that the user configure the cards IRQ Level, I/O Base Address, and Memory Address. The installa-

tion of the ISA Card requires that the user configure the IRQ Level and I/O Base Address. The Symphony PCI Card is automatically assigned an IRQ Level and I/O Base Address by the computers BIOS, therefore these param-

eters are not visible within the PCI Cards Card Setup screen. Configure the card resources (if applicable) and Security Code before proceeding. For the Symphony ISA and PC Card, the IRQ Level, I/O Base Address, and Memory Address (if applicable) must each be configured to a value which is not already in use or reserved by another device in the computer. In addition, the Security Code must be configured so that it matches the Security Code on all of the Symphony products on the network in order to establish communication. Proxim recommends that you leave the Advanced Parameters at the default values. For more information on the Advanced Parameters, see Appendix D. 101 At any time, you may return to the Card Setup screen to reconfigure the Symphony parameters by highlighting the Symphony Adapter entry in the Networks Adapter tab and clicking the <Properties> button. 8. Click <OK> to return to the Network Adapters screen. Install or configure any other required Network parameters, including Services or Protocols. Also, confirm that the TCP/IP protocol is installed under the Protocols tab if you want the computer to have Internet access. In addition, you can change the Computer Name and Domain for the computer under the Identification tab. You may want to change the computers Domain so that it matches the Workgroup designation of the Windows 95/98 computers on the network. Choose <Close> when finished. 9. If you installed TCP/IP, you will be prompted to configure the TCP/IP parameters for the Symphony Card. If you are using the Symphony-HRF Cordless Gateway in NAT mode, select the Obtain an IP address from a DHCP server option and click <OK>, as shown below. 102 If you are using the Cordless Gateway in Transparent Bridging mode only and have a DHCP server on the Ethernet network, then select the Obtain an IP address from a DHCP server option and click <OK>. If you are using the Cordless Gateway in Transparent Bridging mode and do not have a DHCP server on the Ethernet network, you will need to specify an IP Address and Subnet Mask for the Symphony Card that are valid on the Ethernet network. 10. Click <OK> when you have finished configuring the TCP/IP parameters. You may be prompted that one of your adapter cards has an empty primary WINS address. If you do not have a WINS server on the network, click <Yes>

to continue. Restart the computer when prompted. 11. After the computer restarts, the Windows NT driver should be loaded. If you configured the Symphony Card to obtain an IP Address from a DHCP server, a simple test to confirm that the card is working properly is to open an MS-DOS window and type IPCONFIG /ALL at a DOS prompt. This utility will report the IP Address of the Symphony Card and allow you to determine if the Symphony Card successfully received an IP Address from a DHCP server, as shown below. If you manually assigned the Symphony Card an IP Address, a simple test to confirm that the card is working properly is to open an MS-DOS window and attempt to ping another Symphony device. However, if the driver did not load properly, the Windows NT Event Viewer will report that an error has occurred. 103 If the Symphony PCI Card did not install properly, confirm that the computers BIOS is configured to assign resources to the card. If the Symphony ISA or PC Card did not install properly, the card most likely has a resource conflict and is trying to use an IRQ, I/O Base Address, or Memory Range (if applicable) which is either already in use or not available for use by the card. To resolve the conflict, open the Windows NT Diagnos-

tics utility in the Administrative Tools section of the Start Menu and click the Resources tab to view the resources currently in use by the computer. After you have confirmed what resources are available, click the Adapters tab of the Control Panels Network icon and view the properties for the Sym-

phony ISA or PC Card Adapter to return to the Card Setup screen. Change the IRQ, I/O Base Address, or Memory Address (if applicable) to match the resources available for use by the Symphony Card. Hint:

Generally, the IRQ will be the cause of the resource conflict. You may find that your computer has no free IRQ available for use. In this case, try setting the IRQ to a value of 3 or 4, which typically correspond to COM2 and COM1, respectively. If there is no free IRQ available and you are actively using both COM1 and COM2 or other devices are using these resources, then you will need to remove and uninstall one of the other devices from the computer before the Symphony Card may be used. Uninstalling the Windows NT Driver If at any time you need to uninstall the Symphony driver for Windows NT, follow these steps:

1. Remove the device from the Adapters list in the Network icon. 2. Remove the driver file, SYMPHONY.SYS, from the WINNT\SYSTEM32\

DRIVERS directory. 3. Shut down the computer and remove the Symphony Card from the PCMCIA, ISA, or PCI slot. 104 D. Advanced Symphony Parameters Several advanced Symphony parameters are visible within the Advanced tab of the Symphony Cards Properties screen in the Windows 95/98s Network icon and within the Windows NT Card Setup screen. Proxim recommends that you do not alter these advanced parameters from their default values unless told to do so by a Symphony Technical Support representative. Station Type The Symphony Cordless Networking Suite uses a radio technology known as frequency hopping spread spectrum. This means that the frequency at which the devices communicate changes several times a second within a specific radio band. In order for all devices to hop to the appropriate frequency at the same time, one radio must coordinate these movements. This device is known as the Master. A device which follow a Masters pattern is known as a Station. Two Masters cannot communicate with each other. Two Stations can communi-

cate with each other if they have the same Master. At any point in time, each Symphony device is either a Master or a Station. In addition, there is a third Station Type option, Alternate Master, which allows a device to become a Master if one is not present and otherwise it acts as a Station. Multiple Alternate Masters will decide among themselves which device will act as the Master. A Symphony Cordless Modem, a computer running the Symphony Conduc-

tor Sharing Software, and a Symphony-HRF Cordless Gateway are always configured as Masters. Other Symphony devices act as Alternate Masters by default, but this may be changed using the Station Type parameter to be a Master, a Station, or an Alternate Master. Do not change this parameter unless directed to do so by Technical Support. Master Name The Master Name is a string of characters which identifies a Master device. This parameter is only valid for an active Master. Do not change this parameter unless directed to do so by Technical Support. 105 Channel and Subchannel The Channel represents the frequency hopping pattern used by the Master device. The Subchannel provides a logical subdivision between Channels. These parameters are only valid for an active Master device. Do not change these parameters unless directed to do so by Technical Support. MAC Optimize This parameter accounts for the number of radios that are communicating on the Symphony network. By default, this parameter is set to Light in order to maximize throughput and reduce overhead. However, if you have 9 to 10 Symphony devices on the same Symphony network, you may see improved communication by changing this parameter to Normal. However, Proxim does not recommend that you change this parameter unless you are directed to do so by Technical Support. Inactivity Timeout This parameter is only visible for the Symphony PC Card. It controls when a Symphony PC Card will enter a low-power doze mode in order to conserve battery life. The Inactivity Minutes and Inactivity Seconds parameters are added together to arrive at the Inactivity Timeout period. After the specified period of inactivity has elapsed, the Symphony PC Card will enter the doze mode and draw a minimal amount of power from the computer. The card will awaken from doze mode to receive a message directed to it or to send a message to another Symphony device. Setting both Inactivity Seconds and Inactivity Minutes to 0 will prohibit the Symphony PC Card from entering the doze mode. Note that disabling the doze mode will decrease the computers battery life. If you intend to disable the doze mode, you may want to use the computer with AC power. Note:

The Symphony PC Card will not emerge from doze mode in response to a broadcast packet. In general, this is not a problem because communication will typically be initiated from the mobile computer. However, if you need the device to respond to broadcast packets all of the time, you may disable the Inactivity Timeout parameter, as described above. Alternatively, ad-

vanced users may configure a static entry for the Symphony PC Card in other computers ARP table. 106 E.
