work by connecting to another switch or hub. The Uplink Port is shared with Port 4. Uplinking to another switch or a hub is done by simply running a cable from the Uplink Port to the other device. If the Uplink port is being used, Port 4 will not work. The Power Port is where you will connect the included AC Power adapter. The rear panel of the Router is where all of the Routers connections are made. Antenna Jacks The Antenna Jacks are where you will connect the included antennas. The WAN (Wide Area Network) Port is where you will connect your cable or DSL modem. These four LAN (Local Area Network) ports are where you will connect networked devices, such as PCs, print servers, and any other Ethernet devices you want to put on your network. If Port 4 is being used, the Uplink Port will not work. WAN Ports 1-4 3 The Reset Button*

Briefly pressing the Reset Button will refresh the Routers connec-

tions, potentially clearing any jammed links. Pressing the Reset Button and holding it in for a few seconds will clear all of the Routers data and restore the factory defaults. This should be done only if you are experiencing heavy routing problems, and only after you have exhausted all of the other troubleshooting options. By resetting the Router, you run the risk of creating conflicts between your PCs actual IP Addresses and what the Router thinks their IP Addresses should be. You may be forced to reboot the entire system(s). If your router locks up, simply power it down for 3 to 5 seconds by removing the power cable from the Routers Power Port. Leaving the power off for too long could result in the loss of network connections. 4 The Wireless AP + Cable/DSL Routers Front Panel LEDs The WAN Indicators Instant BroadbandTM Series EtherFast Wireless Access Point + Cable/DSL Router with 4-Port Switch The LAN Indicators WLAN Act Green.

Cable/DSL Router consists of more than simply plugging everything together. Because the Router acts as a DHCP server, you will have to set some values within the Router, and also configure your networked PCs to accept the IP Addresses the Router chooses to assign them. You will need the following values from your ISP in order to install the Wireless Access Point + Cable/DSL Router:

Your broadband-configured PCs fixed Internet IP Address (if applicable) Your broadband-configured PCs Computer Name and Workgroup Name Your Subnet Mask Your Default Gateway Your Primary DNS IP address

} Only if applicable Whoever installed your broadband access should have left this information with you. If not, call your ISP and they will be able to supply you with it. About Static & Dynamic IP Addresses Static IP Addresses A static IP address is an IP address permanently assigned to computer in a TCP/IP network. Static IP addresses are usually assigned to networked devices, which are consistently accessed by multiple users, such as Server PCs, or print server. If you are using your Router to share your cable or DSL Internet connection, contact your ISP to see if they have assigned your home a static IP address. You will need that address during your Routers configuration. Dynamic IP Addresses A dynamic IP address is an IP address that is automati-

cally assigned to a client station (computer, printer, etc.) in a TCP/IP network. Dynamic IP addresses are typically assigned by a DHCP server, which can be a computer on the network or another piece of hardware, such as the Router. A dynamic IP address may change every time your computer connects to the network. DHCP (Dynamic Host Configuration Protocol) DHCP is software that automati-

cally assigns IP addresses to client stations logging onto a TCP/IP network. DHCP eliminates having to manually assign permanent IP addresses to every device on your network. DHCP software typically runs in servers and is also found in network devices such as Routers. Connecting Your Hardware Together and Booting Up Once you are sure that you have the above values on hand, you can begin the Installation and Setup of your Wireless Access Point + Cable/DSL Router. 1. Power everything down, including your PCs, your Cable or DSL modem and the Router. 2. Connect a Network cable from one of your PCs Ethernet ports to one of the LAN Ports on the back of the Router. Do the same with all the PCs you wish to connect to the Router. (LAN Port 4 will become inactive if you use the Uplink port.) 3. Connect the network cable from your Cable or DSL modem to the WAN port on the rear of the Router. 4. Connect the power-supply cable to the Power port on the rear of the Router, then plug the supplied AC power cable into a power outlet. The Power LED will illuminate green as soon as the power adapter is connected. The Diag LED will illuminate red for a few seconds while the Router goes through its internal diagnostic test. The LED will turn off when the self-test is complete. 5. Power on the Cable or DSL modem. Verify that the power is on by checking the Link LED in the WAN column on the front of the Router. The Link LED will be illuminated if the power is on and the modem is ready. 7 8 Instant BroadbandTM Series EtherFast Wireless Access Point + Cable/DSL Router with 4-Port Switch 6. Press the Reset button on the back of the router. Hold the button in for three seconds, or until the Diag LED illuminates red. This restores the routers default settings. 7. Power on your PC. Configuring Your PCs to Connect to the Wireless Access Point + Cable/DSL Router Now that your Router is physically installed, you will have to configure your PCs to accept the IP addresses that your Router will provide. The Hardware Installation is complete. Continue to the next page to con-

figure your PCs and Router.

If your ISP assigns you a fixed IP address, click Specify an IP Address and enter the address into the Subnet Mask, Default Gateway Address and DNS fields provided by the ISP. 13 14 Instant BroadbandTM Series EtherFast Wireless Access Point + Cable/DSL Router with 4-Port Switch PPPoE (Point-to-Point Protocol over Ethernet) Some DSL-based ISPs use PPPoE to establish communications with an end-user. If you are using a DSL line, check with your ISP to see if they use PPPoE. If they do use PPPoE, you must enable it. If you do enable PPPoE, remember to remove any existing PPPoE applications already on any of your PCs. To enable PPPoE:

1. Click on the Enable option in the PPPoE section of the Setup screen. 2. Enter the User Name you use to log on to your Internet connection. 3. Enter your corresponding Password. NNoottee:: RAS Settings are for Singapore customers only. If you are a Singapore customer, contact your ISP for RAS Settings before trying to complete this screen. Connect on Demand (Only available if PPPoE is enabled) If you arent actively using the Internet, you can configure your Router to cut your con-

nection with your ISP after a certain period of time. If you have been dis-

connected due to inactivity, Connect on Demand enables your Router to automatically re-establish your connection as soon as you attempt to access the Internet again. If you wish to activate Connect on Demand, choose the Enable option. Max Idle Time (Only available if PPPoE is enabled) Max Idle Time is the number of minutes that passes before the Router drops your Internet con-

nection, due to inactivity. If you want your Internet connection to remain on at all times, enter zero (0) in this field. Otherwise, enter in the number of minutes you want to elapse before your Internet access disconnects. Keep Alive Option (Only available if PPPoE is enabled) This option keeps your PPPoE-enabled Internet access connected indefinitely, even when it sits idle.

WEP (Wired Equivalent Privacy) Encryption is a method of encrypting data that is transmitted over your wireless network to insure data security. In a wired network, data security is maintained through the physical wire. WEP Encryption provides the same level of security for your wireless data as if it were being transmitted over standard network cabling (which is how the name is derived). In order to duplicate wired network security levels, wireless data is encrypted at its point of transmission. It is decoded by the receiving device. This allows users to have the same amount of security over their wireless network as they would over a wired network. This level of security is above that already provided by the use of password protection by your net-

work operating system. The present standard for this encryption, set by the IEEE (the Institute of Electrical and Electronics Engineers), is defined as 40-bit (sometimes also called 64-bit) encryption. Like many manufacturers, Linksys also includes a higher level of encryption, identified as 128-bit. These numbers refer to the complexity of the algorithms generated in order to code and decode the data transmitted. The higher the bit number, the greater the complexity of the algorithm, which is designed to provide a more secure the encryption. Be aware, however, that higher levels of encryption often negatively affect net-

work data transmission rates. This encryption is not necessary for the operation of your wireless network device. Your need for security can only be determined by you. If your security needs are such that ordinary password protection is sufficient, you may decide not to use the additional WEP Encryption. However, should your security needs dictate it, the Wireless Access Point + Cable/DSL Router can provide as secure a connection as is available in wireless networking. 1. At the Setup Screen, if you choose to enable WEP Encryption, select Mandatory under the WEP section. 2. Press the WEP Key Setting button to set the WEP Encryption type and level. NNoottee:: In order for WEP Encryption to be enabled, wireless functions must first be enabled. Select EEnnaabbllee under the Wireless section before prcceeding. 3. The following screen will appear, verifying that you are enabling WEP Encryption. Press the OK button to continue. 4. The following screen will appear, where you will choose your WEP Encryption settings. WEP Encryption key can be generated in one of two ways:

1. You can create an encryption key by using a Passphrase. To generate the encryption key using a passphrase, enter a text string in the Passphrase box and press the Generate button. The Passphrase can be any text string with a maximum of 31 alphanumeric characters. 21 22 2. You may enter the encryption key manually. Password Instant BroadbandTM Series EtherFast Wireless Access Point + Cable/DSL Router with 4-Port Switch

(The Passphrase method is recommended; however, you may need to enter a manual key in order to meet the requirements of existing wireless equip-

ment on your network. If you are unsure, check with your System Administrator.) In either case, you should commit this Passphrase or Manual Key to memory. You will probably need it for other wireless devices on the network. Once you have chosen your key encryption method and entered either the Passphrase or manual key, click the Apply button and the encryption portion of the setup is complete. It is strongly recommended that you set a password for the router. When you first power up the router, you will notice that the Password setting default is admin. For security, we recommend that you change your password often. To change your password, enter your new password in the Router Password box. Enter it again in the box just below the Router Password box, exactly as you typed it in the first box. When you are sure you have entered the pass-

word as you want it, press the Apply button. If you set the Restore Factory Default option and click Apply, you will clear all of the routers settings. Do not restore to the factory defaults unless you want to completely set up the Router again. Once the Router is reset, you will have to re-

enter your configuration. 23 24 Instant BroadbandTM Series EtherFast Wireless Access Point + Cable/DSL Router with 4-Port Switch Status This tab displays the current status of the Router; it reflects data and selec-

tions youve entered under the setup tab. Channel Select the appropriate channel from the list provided to correspond with your network settings, between 1 and 11. All points in your wireless net-

work must use the same channel in order to function correctly. Verify that the correct channel is selected and click the Enable button to set it. DHCP Server This field shows the status of the Router's DHCP server function, which is either enabled or disabled. WAN These fields display the WAN IP Address, WAN Subnet Mask and WAN Default Gateway IP address of the Router, as seen by external users on the Internet. DNS (Domain Name System) IP Address These fields show the IP Address(es) of the DNS currently used by the Router. Multiple DNS IP set-

tings are common. In most cases, the first available DNS entry is used.

When users from the Internet make certain requests of your network, the router will forward those requests to the appropriate computer. The router's DHCP function must be disabled to use Forwarding. Forwarding is generally used to set up a web server, ftp server, or e-mail serv-

er on your network. To add a server using Forwarding:

1. Enter the port number or range used by the server. On the same line, select TCP, UDP or Both. Enter the IP Address of the server that you want the Internet users to be able to access. Refer to your software docu-

mentation for more information concerning which service port settings may need to be changed, if any. 2. Configure as many entries as you would like until all of the link entries are filled. 3. Click Apply to save the settings. 33 With Dynamic Routing you can automatically adjust to physical changes in the network's layout. The router, using the RIP protocol, determines the net-

work packets route based on the fewest number of hops between the source and the destination. The RIP protocol regularly broadcasts routing informa-

tion to other routers on the network. To set up Dynamic Routing:

1. Choose the correct working mode. Gateway Mode should be used if your Linksys router is hosting your network's connection to the Internet. Router Mode should be selected if the router exists on a network with other routers. 2. In the TX field, choose the protocol by which you transmit data on the network. 3. In the RX field, choose the protocol by which the Router receives net-

work data. 4. Click the Apply button to save your changes. 34 Static Routing Static Routing Instant BroadbandTM Series EtherFast Wireless Access Point + Cable/DSL Router with 4-Port Switch 2. Enter the following data to create a new static route:

Destination LAN IP The Destination LAN IP is the Address of the remote network or host to which you want to assign a static route. Enter the IP address of the host for which you wish to create a static route here. If you are building a route to an entire network, be sure that the network portion of the IP address is set to zero (0). For example, the Routers standard IP address is 192.168.1.1. Based on this address, the address of the network to which the Router is connected is 192.168.1, with the last digit (1, in this case) determining the Routers place on the network. Therefore you would enter the IP address 192.168.1.0 if you wanted to route to the Routers entire network, rather than just to the Router. Network Mask The Network Mask (also known as the Subnet Mask) determines which portion of an IP address is the network portion, and which portion is the host portion. In the example above the Network Mask is 255.255.255.0. This determines (by using the values 255) that the first three numbers of an network IP address identify this particular net-

work, while the last digit (from 1 to 254) would identify the specific host. Gateway IP This IP address should be the IP address of the gateway device that allows for contact between the Router and the remote network or host. Hop Count This value gives the number of nodes that a data packet passes through before reaching its destination. A node is any device on the network, such as switches, PCs, etc. Interface This interface tells you whether your network is on the internal LAN or the WAN, or the external Internet. If youre connecting to a sub-

network, select LAN. If youre connecting to another network through the Internet, select WAN. If your Router is connected to more than one network, it may be necessary to set up a static route between them. A static route is a pre-determined pathway that network information must travel to reach a specific host or network. Click the Show Routing Table button to view the current static routing con-

figuration. To create a static route entry:

1. Select Static Route Entry from the drop down list. The Cable/DSL Router supports up to 20 static route entries. 3. Click the Apply button to save your changes. 35 36 DMZ Host MAC Address Cloning Instant BroadbandTM Series EtherFast Wireless Access Point + Cable/DSL Router with 4-Port Switch The DMZ Host setting allows one local computer to be exposed to the Internet to use a special-purpose service such as Internet gaming or video-

conferencing. To expose one computer, enter the computers IP address and click the Apply button. Inactivate DMZ by entering a zero (0). DMZ Host 37 MAC Address Cloning allows you to assign the Router a MAC address, which is a 12-digit code assigned to a unique piece of hardware for identifi-

cation, like a social security number. Some ISPs require that you register the MAC address of your network card/adapter, which was connected to your cable or DSL modem during installation. You can find your adapter's MAC address by doing the following:

If you are running Windows 95, 98 or Millennium:

Go to Start, Run, type in command, and press Enter. At the DOS prompt, type winipcfg. If you are running Windows NT 4.0 or 2000:

Go to Start, Run, type in command, and press Enter. At the DOS prompt, type ipconfig /all. The Physical Address with 12 digits is your adapters MAC address. Enter those 12 digits into the fields on this screen, and click Apply. This clones your network adapters MAC address onto your Router, and prevents you from having to call your ISP to change the registered MAC address to the adapters MAC address. Z Host 38 Instant BroadbandTM Series EtherFast Wireless Access Point + Cable/DSL Router with 4-Port Switch Troubleshooting Common Problems and Solutions This section provides possible solutions to problems regarding the installation and operation of the Wireless Access Point + Cable/DSL Router. If your situ-

ation is described here, the problem should be solved by applying the corre-

sponding solution. If you cant find an answer here, check the Linksys web-

site at www.linksys.com. 1. I Cant connect to the Wireless Access Point + Cable/DSL Router. The Wireless AP + Cable/DSL Router is properly installed, LAN con-

nections are OK, and it is powered ON. Ensure that your PC and the Wireless AP + Cable/DSL Voice Router are on the same network segment. If you are not sure, initiate the DHCP function, let the PC get the IP address automatically. Ensure that your PC is using an IP Address within the default range of 192.168.1.2 to 192.168.1.254 and thus compatible with the Wireless AP

+ Cable/DSL Router default IP Address of 192.168.1.1 Also, the Subnet Mask should be set to 255.255.255.0 to match the Wireless AP + Cable/DSL Router. In the Wireless AP + Cable/DSL Router, you can check these settings by using Control Panel-Network to check the Properties for the TCP/IP protocol. 2. The Diag LED stays lit when it shouldnt. The Diag LED lights up when the device is first powered up. Meantime, the system will boot up itself and check for proper opera-

tion. After finishing the checking procedure, the LED turns off to show the system is working fine. If the LED remains lit after this time, the device is not working properly. Try to re-flash the firmware by assign-

ing a static IP address to the computer, then upgrade the firmware again. If that doesnt help, contact your dealer for further inspection. 3. I cant browse through the Wireless Access Point + Cable/DSL Router. Check if both ends of the network cable and power adapter are properly connected. Check if the status LEDs on the front panel are functioning properly. If using Windows 95 or Windows 98, check the TCP/IP setup on the client side. Run winipcfg by clicking on the Start button, then select-

ing Run, and typing winipcfg in the Run box and press Enter. The PC should have an IP address of 192.168.1.xxx ("xxx" is from 2 to 254.) Subnet Mask is 255.255.255.0, the default gateway IP should be the Routers IP Address, and DNS (in "More".) Same as above, check the same setup values in the Status Monitor page of the Wireless AP + Cable/DSL Router. 4. When I enter a URL or IP address, I get a time out error. Check if other PCs work. If they do, ensure that your workstations IP settings are correct (IP address, Subnet Mask, Default gateway and DNS) If the PCs are configured correctly, but still not working, check the Wireless Access Point + Cable/DSL Router. Ensure that it is connected and ON. Connect to it and check its settings. (If you cannot connect to it, check the LAN and power connections.) If the Cable/DSL Router is configured correctly, check your Internet connection. (DSL/Cable modem etc.) to see that it is working correctly. Manually configure the TCP/IP with a DNS address provided by your ISP. 5. I cant obtain an IP address from my cable or DSL modem. Ensure that all of your cabling is properly connected and that all of the routers WAN and LAN LEDs are correctly illuminated. Power down your cable or DSL modem for a few seconds. Turn it back on. After the modem goes through its self-test, check to see if you now have an IP address. Ensure that your cable or DSL modem is DHCP-capable. You may have to enter the router or host name in the Setup page of the Routers web-based utility. Go to the Setup section of the Web-based Utility for more information. Your ISP may require Mac Addresses. Check with your ISP. This address can be obtained in the Status screen of the Routers Web-based Utility. Frequently Asked Questions 39 40 Instant BroadbandTM Series EtherFast Wireless Access Point + Cable/DSL Router with 4-Port Switch Frequently Asked Questions What is the maximum number of IP addresses that the Wireless Access Point +

Cable/DSL Router will support? The Router will support up to 253 IP address-

es. Is IPSec Pass-Thru supported by the Router? Yes, it is a built-in feature that the router automatically enables. Where is the Wireless Access Point +Cable/DSL Router installed on the network?

In a typical environment, the Router is installed between the Cable/DSL Modem and the LAN. Plug the Wireless AP +Cable/DSL Router into the Cable/DSL Modem's Ethernet port. Does the Wireless Access Point + Cable/DSL Router support IPX or AppleTalk?

No. TCP/IP is the only protocol standard for the Internet and has become the global standard for communications. IPX, a NetWare communications protocol used only to route messages from one node to another, and AppleTalk, a communications protocol used on Apple and Macintosh net-

works, can be used from LAN to LAN connections, but those protocols can-

not connect from WAN to LAN. Does the WAN connection of the Wireless Access Point + Cable/DSL Router sup-

port 100Mb Ethernet? Because of the speed limitations of broadband Internet connections, the Cable/DSL Routers current hardware design supports 10Mb Ethernet on its WAN port. It does, of course, support 100Mbps over in the auto-sensing Fast Ethernet 10/100 switch on the LAN side of the router. What is Network Address Translation and what is it used for? Network Address Translation (NAT) translates multiple IP addresses on the private LAN to one public address that is sent out to the Internet. This adds a level of security since the address of a PC connected to the private LAN is never transmitted on the Internet. Furthermore, NAT allows the Cable/DSL Router to be used with low cost Internet accounts, such as DSL or cable modems, where only one TCP/IP address is provided by the ISP. The user may have many private addresses behind this single address provided by the ISP. Does the Wireless Access Point + Cable/DSL Router support any operating sys-

tem other than Windows 95, Windows 98, Windows 2000, or Windows NT? Yes, but Linksys does not, at this time, provide technical support for setup, con-

figuration or troubleshooting of any non-Windows operating systems. Does the Cable/DSL router support ICQ send file? Yes, with the following fix:

ICQ menu-> preference -> connections tab-> check "I am behind a firewall or proxy", and set the firewall time-out to 80 seconds in firewall setting. The Internet user can then send a file to a user behind the router. How do I get Napster to work with the Router? Napster is fully compatible with the Router, but you must make sure that, during installation, you select no idea when asked about your firewall selection. Set your proxy settings to No Proxy Server in your File>Preferences. I setup an Unreal Tournament Server, but others on the LAN cannot join. What do I need to do? If you have a dedicated Unreal Tournament server running, you need to create a static IP for each of the LAN computers and forward ports 7777, 7778, 7779, 7780, 7781, and 27900 to the IP address of the server. If you want to use the UT Server Admin, forward another port (8080 usually works well), then in the [UWeb.WebServer] section of the server.ini file, set the ListenPort to 8080 (to match the mapped port above) and ServerName to the IP assigned to the router from your ISP. Can multiple gamers on the LAN get on one game server and play simultaneous-

ly with just one public IP address? It depends on the which network game or what kind of game server you are using. For example, Unreal Tournament supports multi-login with one public IP. How do I get Half-Life:Team Fortressto Work with the Router? The default client port for Half-Life is 27005. The computers on your LAN need to have "+clientport 2700x" to the HL shortcut command line; the x would be 6, 7, 8, and on up. This lets multiple computers connect to the same server. One problem: version 1.0.1.6 won't let multiple computers with the same CD key connect at the same time, even if on the same LAN (not a problem with 1.0.1.3). As far as hosting games, the HL server does not need to be in the DMZ. Just forward port 27015 to the local IP of the server computer. There remains, however, a problem with people being booted after a few minutes with an "illegible server message."

41 42 Instant BroadbandTM Series EtherFast Wireless Access Point + Cable/DSL Router with 4-Port Switch Web page hangs, corrupt downloads, or nothing but junk characters are being displayed on the screen. What do I need to do? Force your NIC to 10Mbps or half duplex mode, and turn off the "Auto-negotiate" feature of your NIC as a temporary measure. (Please look at the Network Control Panel, in your Ethernet Adapter's Advanced Properties tab.). Make sure that your proxy setting is disabled in the browser. Check our website at www.linksys.com for more information. If all else fails in the installation, what can I do? Reset the router by holding down the reset button for at least three seconds and reset your cable or DSL modem by powering the unit off and then on. Obtain and flash the latest firmware release that is readily available on Linksys website, www.linksys.com. How will I be notified of new router firmware upgrades? All Linksys firmware upgrades are posted on the Linksys website at www.linksys.com, where they can downloaded for free. The router's firmware can be upgraded with TFTP programs. Does the Wireless Access Point + Cable/DSL Router support IPSec? Yes, but only pass through IPSec is supported. Will the router function in a Macintosh environment? Yes, but the router's setup pages are accessible only through Internet Explorer v4.0 or Netscape Navigator v4.0 or higher for Macintosh. With which type of firewall is the router equipped? The Wireless AP +

Cable/DSL router uses NAT and TCP/IP port inspections. Does the Router do Stateful packet inspection? No I am not able to get the web configuration screen for the router. What can I do?

You may have to remove the proxy settings on your Internet browser, e.g., Netscape Navigator or Internet Explorer. Or remove the dial-up settings on your browser. Check with your browser documentation. What is DMZ? Demilitarized Zone (DMZ) allows one IP Address (computer) to be exposed to the Internet. Some applications require multiple TCP/IP ports to be open. It is recommended that you set your computer with a stat-

ic IP if you want to use DMZ. If DMZ is used, does the exposed user share the public IP with the Router? No. Does the Router pass PPTP packets or actively route PPTP sessions? The router allows PPTP packets to pass through. Is the Router cross-platform compatible? Any platform that supports Ethernet and TCP/IP is compatible with the router. Will the Router allow me to use my own public IPs and Domain, or do I have to use the IPs provided by the router? The router mode allows for customiza-

tion of your public IPs and Domain. How many ports can be simultaneously forwarded? Theoretically, the router can establish 520 sessions at the same time, but you can only forward 10 ranges of ports. Does the Router replace a modem? Is there a cable or DSL modem in the router? No, this version of the router must work in conjunction with a cable or DSL modem. Which modems are compatible with the router? The router is compatible with virtually any cable or DSL modem that supports Ethernet. What are the advanced features of the router? The router's advanced features include Filters, Forwarding, Dynamic Routing, Static Routing, and DMZ host. Does Linksys provide syslog support? No, Linksys does not currently provide syslog support. How can I check whether I have static DHCP IP Addresses? Consult your ISP to confirm the information. How do I get mIRC to work with the Router? Set port forwarding to 113 for the computer on which you are using mIRC. If you are experiencing difficulty after setting the port forwarding, try changing the Direct Client-to-Client

(DCC) settings to a range from 1024 to 1030 on the DCC option and Forwarding page of the Web-based Setup Utility. If your questions are not addressed here, refer to the contact information on the last page of this manual. 43 44 Instant BroadbandTM Series EtherFast Wireless Access Point + Cable/DSL Router with 4-Port Switch Appendix How to Ping Your ISPs E-mail & Web Addresses How to Ping Your ISPs E-mail & Web Addresses Virtually all Internet addresses are configured with words or characters (i.e., www.linksys.com, www.yahoo.com, etc.) In actuality, however, these Internet addresses are assigned to IP addresses, which are the true addresses on the Internet. For example, www.linksys.com is actually 216.23.162.142. Type it into your web browser and you will wind up at the Linksys home page every time. IP and web addresses, however, can sometimes be long and hard to remem-

ber. Because of this, certain ISPs will shorten their server addresses to single words or codes on their users web browser or e-mail configurations. If your ISPs E-mail and Web server addresses are configured with single words

(www, e-mail, home, pop3, etc.) rather than whole Internet Addresses or IP Addresses, your Router may have problems sending or receiving mail and accessing the Internet. This happens because your Router has not been configured by your ISP to accept their abbreviated server addresses. The solution is to determine the true web addresses behind your ISPs code words. You can determine the IP and web addresses of your ISPs servers by pinging them. If you dont have your ISPs web and e-mail IP Addresses, you must either get them from your ISP or follow these steps prior to connecting your Cable/DSL Router to your network. Step One: Pinging an IP Address The first step to determining your ISPs web and e-mail server address is to ping its IP Address. 1. Power on the computer and the cable or DSL modem, and restore the network configuration set by your ISP if you have since changed it. 2. Click Start, then Run, and type "command". This will bring up the DOS Window. 45 3. At the DOS command prompt, type "ping mail" (assuming that the location for which youre trying to find an IP address is configured as mail). Press Enter. Information such as the following data, taken from a ping of Microsoft Networks e-mail server, will be displayed. C:\>ping mail Pinging mail [24.53.32.4] with 32 bytes of data:

This IP address is the actual IP address of the server mail, or any other word or value you have pinged. Step Two: Pinging for a Web Address While the IP address returned above would work as your e-mail server address, it may not be permanent. IP Addresses change all the time. Web addresses, however, usually dont. Because of this, youre likely to have less problems by configuring your system with web addresses rather than IP addresses. Follow the instructions below to find the web address assigned to the IP address you just pinged. 1. At the DOS command prompt, type ping -a 24.53.32.4, where 24.53.32.4 is the IP address you just pinged. Information such as the fol-

Twisted-Pair Cabling Instant BroadbandTM Series EtherFast Wireless Access Point + Cable/DSL Router with 4-Port Switch There are different grades, or categories, of twisted-pair cabling. Category 5 is the most reliable and is highly recommended. Category 3 is a good second choice. Straight-through cables are used for connecting computers to a hub. Crossover cables are used for connecting a hub to another hub (there is an exception: some hubs have a built-in uplink port that is crossed internally, which allows you to link or connect hubs together with a straight-through cable instead). You can buy pre-made Category 5 cabling, or cut and crimp your own. Category 5 cables can be purchased or crimped as either straight-through or crossover. Inside a Category 5 cable are 8 thin, color-coded wires inside that run from one end of the cable to the other. All 8 wires are used. In a straight-through cable, wires 1, 2, 3, and 6 at one end of the cable are also wires 1, 2, 3, and 6 at the other end. In a crossover cable, the order of the wires change from one end to the other: wire 1 becomes 3, and 2 becomes 6. See the diagrams on the next page for more detailed information on straight-through and crossover cabling. To determine which wire is wire number 1, hold the cable so that the end of the plastic RJ-45 tip (the part that goes into a wall jack first) is facing away from you. Face the clip down so that the copper side faces up (the springy clip will now be parallel to the floor).When looking down on the copper side, wire 1 will be on the far left. 50 7. After a few seconds you will be brought back to the main Network win-

dow. The TCP/IP Protocol should now be listed. 8. Click OK. Windows may ask for original Windows installation files. Supply them as needed (i.e.: D:\win98, D:\win95, c:\windows\options\cabs.) 9. Windows will ask you to restart the PC. Click Yes.

work in which some of the network devices are part of the network only for the duration of a communications session while in some close proximity to the rest of the network. BSS (Basic Service Set) - A group of Instant WirelessTM Network PC Card users and a Wireless AP + Cable/DSL Router. Default Gateway - The router used to forward all traffic that is not addressed to a station within the local subnet. DHCP (Dynamic Host Configuration Protocol) - Aprotocol that lets network administrators manage centrally and automate the assignment of Internet Protocol (IP) addresses in an organization's network. Using the Internet's set of protocol (TCP/IP), each machine that can connect to the Internet needs a unique IP address. When an organization sets up its computer users with a con-

nection to the Internet, an IP address must be assigned to each machine. Without DHCP, the IP address must be entered manually at each computer and, if computers move to another location in another part of the network, a new IP address must be entered. DHCP lets a network administrator supervise and dis-

tribute IP addresses from a central point and automatically sends a new IP address when a computer is plugged into a different place in the network. DHCP uses the concept of a "lease" or amount of time that a given IP address will be valid for a computer. The lease time can vary depending on how long a user is likely to require the Internet connection at a particular location. It's espe-

cially useful in education and other environments where users change fre-

quently. Using very short leases, DHCP can dynamically reconfigure networks in which there are more computers than there are available IP addresses. DHCP supports static addresses for computers containing Web servers that need a permanent IP address. DMZ - A DMZ (demilitarized zone) is a computer host or small network inserted as a "neutral zone" between a company's private network and the out-

side public network. It prevents outside users from getting direct access to a server that has company data. 51 52 Instant BroadbandTM Series EtherFast Wireless Access Point + Cable/DSL Router with 4-Port Switch DNS - The domain name system (DNS) is the way that Internet domain name are located and translated into Internet Protocol (IP) addresses. A domain name is a meaningful and easy-to-remember "handle" for an Internet address. DSSS - Also known as Direct Sequence Spred Spectrum, this is a variety of radio transmission methods that continuously change frequencies or signal pat-

terns. Direct sequence spread spectrum (DSSS), which is used in CDMA, mul-

tiplies the data bits by a very fast pseudo-random bit pattern (PN sequence) that

"spreads" the data into a large coded stream that takes the full bandwidth of the channel Dynamic IP Address - An IP address that is automatically assigned to a client station in a TCP/IP network, typically by a DHCP server. Network devices that serve multiple users, such as servers and printers, are usually assigned static IP addresses. ESS - More than one BSS in a network. FHSS - Also known as Frequency Hopping Spread Spectrum. Frequency hopping spread spectrum (FHSS) continuously changes the center frequency of a conventional carrier several times per second according to a pseudo-random set of channels, while chirp spread spectrum changes the carrier frequency. Because a fixed frequency is not used, illegal monitoring of spread spectrum signals is extremely difficult, if not downright impossible depending on the particular method. Firewall - A firewall is a set of related programs, located at a network gateway server, that protects the resources of a network from users from other networks.

(The term also implies the security policy that is used with the programs.) An enterprise with an intranet that allows its workers access to the wider Internet installs a firewall to prevent outsiders from accessing its own private data resources and for controlling what outside resources to which its own users have access. Basically, a firewall, working closely with a router program, examines each network packet to determine whether to forward it toward its destination. Firmware - Programming that is inserted into programmable read-only mem-

ory (programmable read-only memory), thus becoming a permanent part of a computing device. IEEE - The Institute of Electrical and Electronics Engineers. The IEEE describes itself as "the world's largest technical professional society -- promot-

ing the development and application of electrotechnology and allied sciences for the benefit of humanity, the advancement of the profession, and the well-

being of our members."

The IEEE fosters the development of standards that often become national and international standards. The organization publishes a number of journals, has many local chapters, and several large societies in special areas, such as the IEEE Computer Society. Infrastructure - An infrastructure network is a wireless network or other small network in which the wireless network devices are made a part of the network through the Access Point which connects them to the rest of the network. IP Address - In the most widely installed level of the Internet Protocol

(Internet Protocol) today, an IP address is a 32-binary digit number that identi-

fies each sender or receiver of information that is sent in packet across the Internet. When you request an HTML page or send e-mail, the Internet Protocol part of TCP/IP includes your IP address in the message (actually, in each of the packets if more than one is required) and sends it to the IP address that is obtained by looking up the domain name in the Uniform Resource Locator you requested or in the e-mail address you're sending a note to. At the other end, the recipient can see the IP address of the Web page requestor or the e-mail sender and can respond by sending another message using the IP address it received. IPCONIFG - A utility that provides for querying, defining and managing IP addresses within a network. A commonly used utility, under Windows NT and 2000, for configuring networks with static IP addresses. IPSec - IPSec (Internet Protocol Security) is a developing standard for securi-

ty at the network or packet processing layer of network communication. A big advantage of IPSec is that security arrangements can be handled without requiring changes to individual user computers. ISP - An ISP (Internet service provider) is a company that provides individuals and companies access to the Internet and other related services such as Web site building and virtual hosting. 53 54 Instant BroadbandTM Series EtherFast Wireless Access Point + Cable/DSL Router with 4-Port Switch LAN - A local area network (LAN) is a group of computers and associated devices that share a common communications line and typically share the resources of a single processor or server within a small geographic area (for example, within an office building). MAC Address - The MAC (Media Access Control) address is your computer's unique hardware number. mIRC - mIRC runs under Windows and provides a graphical interface for log-

ging onto IRC servers and listing, joining and leaving channels. NAT - NAT (Network Address Translation) is the translation of an Internet Protocol address (IP address) used within one network to a different IP address known within another network. One network is designated the inside network and the other is the outside. Network Mask - also known as the Subnet Mask. Packet Filtering - Discarding unwanted network traffic based on its originat-

ing address or range of addresses or its type (e-mail, file transfer, etc.). PCMCIA - The PCMCIA (Personal Computer Memory Card International Association) is an industry group organized in 1989 to promote standards for a credit card-size memory or I/O device that would fit into a personal computer, usually a notebook or laptop computer. Ping - (Packet INternet Groper) An Internet utility used to determine whether a particular IP address is online. It is used to test and debug a network by send-

ing out a packet and waiting for a response. PPPoE (Point to Point Protocol over Ethernet) - A method used mostly by DSL providers for connecting personal computers to a broadband modem for Internet access. It is similar to how a dial-up connection works but at higher speeds and quicker access. PPTP (Point-to-Point Tunneling Protocol) - A protocol (set of communication rules) that allows corporations to extend their own corporate network through private "tunnels" over the public Internet. Effectively, a corporation uses a wide-area network as a single large local area network. A company no longer needs to lease its own lines for wide-area communication but can securely use the public networks. This kind of interconnection is known as a virtual private network. PrintServer - A hardware device that enables a printer to be located anywhere in the network. RJ-45 - A connector similar to a telephone connector that holds up to eight wires, used for connecting Ethernet devices. Roaming - The ability to use a wireless device and be able to move from one access points range to another without losing the connection. Static IP Address - A permanent IP address that is assigned to a node in a TCP/IP network. Subnet Mask - The method used for splitting IP networks into a series of sub-

groups, or subnets. The mask is a binary pattern that is matched up with the IP address to turn part of the host ID address field into a field for subnets. TCP (Transmission Control Protocol) - A method (protocol) used along with the Internet Protocol (Internet Protocol) to send data in the form of message units between computers over the Internet. While IP takes care of handling the actual delivery of the data, TCP takes care of keeping track of the individual units of data (called packet) that a message is divided into for efficient routing through the Internet. TCP/IP - Transmission Control Protocol/Internet Protocol (TCP/IP) is the basic communication language or protocol of the Internet. It can also be used as a communications protocol in a private network (either an intranet or an extranet). When you are set up with direct access to the Internet, your comput-

er is provided with a copy of the TCP/IP program just as every other computer that you may send messages to or get information from also has a copy of TCP/IP. UDP (User Datagram Protocol) - A communications method (protocol) that offers a limited amount of service when messages are exchanged between com-

puters in a network that uses the Internet Protocol (IP). UDP is an alternative to the Transmission Control Protocol (TCP) and, together with IP, is sometimes referred to as UDP/IP. Like the Transmission Control Protocol, UDP uses the Internet Protocol to actually get a data unit (called a datagram) from one com-

puter to another. Unlike TCP, however, UDP does not provide the service of dividing a message into packets (datagrams) and reassembling it at the other end. Specifically, UDP doesn't provide sequencing of the packets that the data arrives in. This means that the application program that uses UDP must be able to make sure that the entire message has arrived and is in the right order. 55 56 Instant BroadbandTM Series EtherFast Wireless Access Point + Cable/DSL Router with 4-Port Switch Network applications that want to save processing time because they have very small data units to exchange (and therefore very little message reassembling to do) may prefer UDP to TCP. UTP - Unshielded twisted pair is the most common kind of copper telephone wiring. Twisted pair is the ordinary copper wire that connects home and many business computers to the telephone company. To reduce crosstalk or electro-

magnetic induction between pairs of wires, two insulated copper wires are twisted around each other. Each signal on twisted pair requires both wires. Since some telephone sets or desktop locations require multiple connections, twisted pair is sometimes installed in two or more pairs, all within a single cable. Virtual Server - Multiple servers that appear as one server, or one system image, to the operating system or for network administration WAN - A communications network that covers a wide geographic area, such as state or country. WEP (Wired Equivalent Privacy) - A data privacy mechanism based on a 64-

bit shared key algorithm, as described in the IEEE 802.11 standard. WINIPCFG - Configuration utility based on the Win32 API for querying, defining and managing IP addresses within a network. A commonly used util-

ity, under Windows 95, 98, and Millennium, for configuring networks with static IP addresses. Specifications Model Number Standards Protocol Ports WAN:
