The Compact Wireless-G Broadband Router will allow you to network wirelessly better than ever, sharing Internet access, files and fun, easily and securely. How does the Compact Wireless-G Broadband Router do all of this? A router is a device that allows access to an Internet connection over a network. With the Compact Wireless-G Broadband Router, this access can be shared over the four switched ports or via the wireless broadcast at either up to 11Mbps for Wireless-B or up to 54Mbps for Wireless-G. In addition, the whole network is protected by NAT technology. For wireless networking, you also have a choice of wireless security methods. Additional security features, as well as configuration options, are accessible through the easy-to-use, browser-based utility. But what does all of this mean?
Networks are useful tools for sharing computer resources. You can access one printer from different computers and access data located on another computer's hard drive. Networks are even used for playing multiplayer video games. So, networks are not only useful in homes and offices, they can also be fun. PCs on a wired network create a LAN, or Local Area Network. They are connected with Ethernet cables, which is why the network is called wired. PCs equipped with wireless cards or adapters can communicate without cumbersome cables. By sharing the same wireless settings, within their transmission radius, they form a wireless network. This is sometimes called a WLAN, or Wireless Local Area Network. The Compact Wireless-G Broadband Router bridges wireless networks of 802.11a, 802.11b, and 802.11g standards and wired networks, allowing them to communicate with each other. With your wired and wireless networks connected to each other and the Internet, you can now share files and Internet accessand even play games. All the while, the Compact Wireless-G Broadband Router protects your networks from unauthorized and unwelcome users. Linksys recommends using the Setup CD-ROM for first-time installation of the Router. If you do not wish to run the Setup Wizard on the Setup CD-ROM, then use the instructions in this Guide to help you connect the Compact Wireless-G Broadband Router, set it up, and configure it to bridge your different networks. These instructions should be all you need to get the most out of the Compact Wireless-G Broadband Router. nat (network address translation): NAT technology translated IP addresses of a local area network to a different IP address for the Internet. mbps: one million bits per second; a unit of measurement for data transmission. browser: an application program that provides a way to look at and interact with all the information on the World Wide Web. lan (local area network): the computers and networking products that make up the network in your home or office. ethernet: an IEEE standard network protocol that specifies how data is placed on and retrieved from a common transmission medium. 802.11b: an IEEE wireless networking standard that specifies a maximum data transfer rate of 11Mbps and an operating frequency of 2.4GHz. 802.11g: an IEEE wireless networking standard that specifies a maximum data transfer rate of 54Mbps, an operating frequency of 2.4GHz, and backward compatibility with 802.11b devices.

3 Compact Wireless-G Broadband Router Chapter 2: Planning Your Wireless Network Network Topology A wireless local area network (WLAN) is exactly like a regular local area network (LAN), except that each computer in the WLAN uses a wireless device to connect to the network. Computers in a WLAN share the same frequency channel and SSID, which is an identification name shared by the wireless devices belonging to the same wireless network. network: a series of computers or devices connected for the purpose of data sharing, storage, and/or transmission between users. Ad-Hoc versus Infrastructure Mode Unlike wired networks, wireless networks have two different modes in which they may be set up: infrastructure and ad-hoc. An infrastructure configuration is a WLAN and wired LAN communicating to each other through an access point. An ad-hoc configuration is wireless-equipped computers communicating directly with each other. Choosing between these two modes depends on whether or not the wireless network needs to share data or peripherals with a wired network or not. If the computers on the wireless network need to be accessible by a wired network or need to share a peripheral, such as a printer, with the wired network computers, the wireless network should be set up in Infrastructure mode. The basis of Infrastructure mode centers around a wireless router or an access point, such as the Compact Wireless-G Broadband Router, which serves as the main point of communications in a wireless network. The Router transmits data to PCs equipped with wireless network adapters, which can roam within a certain radial range of the Router. You can arrange the Router and multiple access points to work in succession to extend the roaming range, and you can set up your wireless network to communicate with your Ethernet hardware as well. If the wireless network is relatively small and needs to share resources only with the other computers on the wireless network, then the Ad-Hoc mode can be used. Ad-Hoc mode allows computers equipped with wireless transmitters and receivers to communicate directly with each other, eliminating the need for a wireless router or access point. The drawback of this mode is that in Ad-Hoc mode, wireless-equipped computers are not able to communicate with computers on a wired network. And, of course, communication between the wireless-
equipped computers is limited by the distance and interference directly between them. Network Layout The Compact Wireless-G Broadband Router has been specifically designed for use with your 802.11b and 802.11g products. Now, products using these standards can communicate with each other. ssid: your wireless networks name. ad-hoc: a group of wireless devices communicating directly to each other
(peer-to-peer) without the use of an access point. infrastructure: a wireless network that is bridged to a wired network via an access point. adapter: a device that adds network functionality to your PC. ethernet: IEEE standard network protocol that specifies how data is placed on and retrieved from a common transmission medium. access point: a device that allows wireless-
equipped computers and other devices to communicate with a wired network. Also used to expand the range of a wireless network. Chapter 2: Planning Your Wireless Network Network Topology 4 Compact Wireless-G Broadband Router The Compact Wireless-G Broadband Router is compatible with all 802.11b and 802.11g adapters, such as the Notebook Adapters for your laptop computers, PCI Adapters for your desktop PCs, and USB Adapters when you want to enjoy USB connectivity. The Router will also communicate with the Wireless PrintServer and Wireless Ethernet Bridges. When you wish to connect your wireless network with your wired network, you can use the Compact Wireless-G Broadband Routers four LAN ports. To add more ports, any of the Compact Wireless-G Broadband Router's LAN ports can be connected to any of Linksys's switches. With these, and many other, Linksys products, your networking options are limitless.

These settings should only be adjusted by an expert administrator as incorrect settings can reduce wireless performance. Advanced Wireless Wireless-G Settings Authentication Type. The default is set to Auto (Default), allows either Open System or Shared Key authentication to be used. With Open System authentication, the sender and the recipient do NOT use a WEP key for authentication. With Shared Key authentication, the sender and recipient use a WEP key for authentication. Transmission Rate. The rate of data transmission should be set depending on the speed of your wireless network. You can select from a range of transmission speeds, or you can select Auto (Default) to have the Router automatically use the fastest possible data rate and enable the Auto-Fallback feature. Auto-Fallback will negotiate the best possible connection speed between the Router and a wireless client. The default value is Auto
(Default). Basic Rate. The Basic Rate setting is not actually one rate of transmission but a series of rates at which the Router can transmit. The Router will advertise its Basic Rate to the other wireless devices in your network, so they know which rates will be used. The Router will also advertise that it will automatically select the best rate for transmission. The default setting is Default, when the Router can transmit at all standard wireless rates
(1-2Mbps, 5.5Mbps, 11Mbps, 18Mbps, and 24Mbps). Other options are 1-2Mbps, for use with older wireless technology, and All, when the Router can transmit at all wireless rates. The Basic Rate is not the actual rate of data transmission. If you want to specify the Routers rate of data transmission, configure the Transmission Rate setting. CTS Protection Mode. CTS (Clear-To-Send) Protection Mode should be set to Auto (Default). The Router will automatically use CTS Protection Mode when your Wireless-G products are experiencing severe problems and are not able to transmit to the Router in an environment with heavy 802.11b traffic. This function boosts the Routers ability to catch all Wireless-G transmissions but will severely decrease performance. DTIM Interval. This value indicates the interval of the Delivery Traffic Indication Message (DTIM). A DTIM field is a countdown field informing clients of the next window for listening to broadcast and multicast messages. When the Router has buffered broadcast or multicast messages for associated clients, it sends the next DTIM with a DTIM Interval value. Its clients hear the beacons and awaken to receive the broadcast and multicast messages. The default value is 1. Figure 5-21: Wireless Tab - Advanced Wireless Settings cts (clear to send): a signal sent by a wireless device, signifying that it is ready to receive data. dtim: a message included in data packets that can increase wireless efficiency. Chapter 5: Configuring the Compact Wireless-G Broadband Router The Wireless Tab - Advanced Wireless Settings 25 Compact Wireless-G Broadband Router Fragmentation Threshold. This value specifies the maximum size for a packet before data is fragmented into multiple packets. If you experience a high packet error rate, you may slightly increase the Fragmentation Threshold. Setting the Fragmentation Threshold too low may result in poor network performance. Only minor reduction of the default value is recommended. In most cases, it should remain at its default value of 2346. fragmentation: breaking a packet into smaller units when transmitting over a network medium that cannot support the original size of the packet. RTS Threshold. Should you encounter inconsistent data flow, only minor reduction of the default value, 2347, is recommended. If a network packet is smaller than the preset RTS threshold size, the RTS/CTS mechanism will not be enabled. The Router sends Request to Send (RTS) frames to a particular receiving station and negotiates the sending of a data frame. After receiving an RTS, the wireless station responds with a Clear to Send (CTS) frame to acknowledge the right to begin transmission. The RTS Threshold value should remain at its default value of 2347. Beacon Interval. The default value is 100. The Beacon Interval value indicates the frequency interval of the beacon. A beacon is a packet broadcast by the Router to synchronize the wireless network.

Turn off the computer, Router, and cable/DSL modem. Wait 30 seconds, and then turn on the Router, cable/DSL modem, and computer. Check the Status tab of the Routers web-based utility to see if you get an IP address. Appendix A: Troubleshooting Common Problems and Solutions 44 Compact Wireless-G Broadband Router 5. I am not able to access the Setup page of the Routers web-based utility.
Refer to Problem #2, I want to test my Internet connection to verify that your computer is properly connected to the Router.
Refer to Appendix E: Finding the MAC Address and IP address for Your Ethernet Adapter to verify that your computer has an IP Address, Subnet Mask, Gateway, and DNS.
Set a static IP address on your system; refer to Problem #1: I need to set a static IP address.
Refer to Problem #10: I need to remove the proxy settings or the dial-up pop-up window (for PPPoE users). 6. I need to set up a server behind my Router and make it available to the public. To use a server like a web, ftp, or mail server, you need to know the respective port numbers they are using. For example, port 80 (HTTP) is used for web; port 21 (FTP) is used for FTP, and port 25 (SMTP outgoing) and port 110 (POP3 incoming) are used for the mail server. You can get more information by viewing the documentation provided with the server you installed. Follow these steps to set up port forwarding through the Routers web-based utility. We will be setting up web, ftp, and mail servers. 1. Access the Routers web-based utility by going to http://192.168.1.1 or the IP address of the Router. Go to the Applications & Gaming => Port Range Forwarding tab. 2. Enter any name you want to use for the custom Application. 3. Enter the External Port range of the service you are using. For example, if you have a web server, you would enter the range 80 to 80. 4. Check the protocol you will be using, TCP and/or UDP. 5. Enter the IP address of the PC or network device that you want the port server to go to. For example, if the web servers Ethernet adapter IP address is 192.168.1.100, you would enter 100 in the field provided. Check Appendix E: Finding the MAC Address and IP Address for Your Ethernet Adapter for details on getting an IP address. 6. Check the Enabled option for the port services you want to use. Consider the example below:
Application Start ~ End Port Protocol IP Address Enabled Web server FTP server SMTP (outgoing) 80 to 80 21 to 21 25 to 25 POP3 (incoming) 110 to 110 Both TCP Both Both 192.168.1.100 192.168.1.101 192.168.1.102 192.168.1.102 X X X X When you have completed the configuration, click the Save Settings button. Appendix A: Troubleshooting Common Problems and Solutions 45 Compact Wireless-G Broadband Router 7. I need to set up online game hosting or use other Internet applications. If you want to play online games or use Internet applications, most will work without doing any port forwarding or DMZ hosting. There may be cases when you want to host an online game or Internet application. This would require you to set up the Router to deliver incoming packets or data to a specific computer. This also applies to the Internet applications you are using. The best way to get the information on what port services to use is to go to the website of the online game or application you want to use. Follow these steps to set up online game hosting or use a certain Internet application:
1. Access the Routers web interface by going to http://192.168.1.1 or the IP address of the Router. Go to the Applications & Gaming => Port Range Forwarding tab. 2. Enter any name you want to use for the custom Application. 3. Enter the External Port range of the service you are using. For example, if you want to host Unreal Tournament (UT), you would enter the range 7777 to 27900. 4. Check the protocol you will be using, TCP and/or UDP. 5. Enter the IP address of the PC or network device that you want the port server to go to. For example, if the web servers Ethernet adapter IP address is 192.168.1.100, you would enter 100 in the field provided. Check Appendix E: Finding the MAC Address and IP Address for Your Ethernet Adapter for details on getting an IP address. 6. Check the Enabled option for the port services you want to use. Consider the example below:
Application Start ~ End Port Protocol IP Address Enabled UT Halflife 7777 to 27900 27015 to 27015 PC Anywhere 5631 to 5631 VPN IPSEC 500 to 500 Both Both UDP UDP 192.168.1.100 192.168.1.105 192.168.1.102 192.168.1.100 X X X X When you have completed the configuration, click the Save Settings button. 8. I cant get the Internet game, server, or application to work. If you are having difficulties getting any Internet game, server, or application to function properly, consider exposing one PC to the Internet using DeMilitarized Zone (DMZ) hosting. This option is available when an application requires too many ports or when you are not sure which port services to use. Make sure you disable all the forwarding entries if you want to successfully use DMZ hosting, since forwarding has priority over DMZ hosting. (In other words, data that enters the Router will be checked first by the forwarding settings. If the port number that the data enters from does not have port forwarding, then the Router will send the data to whichever PC or network device you set for DMZ hosting.) Appendix A: Troubleshooting Common Problems and Solutions 46 Compact Wireless-G Broadband Router Follow these steps to set DMZ hosting:
1. Access the Routers web-based utility by going to http://192.168.1.1 or the IP address of the Router. Go to the Applications & Gaming => Port Range Forwarding tab. 2. Disable or remove the entries you have entered for forwarding. Keep this information in case you want to use it at a later time. 3. Go to the Applications & Gaming => DMZ tab. 4. Select Enabled next to DMZ. In the Host IP Address field, enter the IP address of the computer you want exposed to the Internet. This will bypass the NAT technology for that computer. Please refer to Appendix E: Finding the MAC Address and IP Address for Your Ethernet Adapter for details on getting an IP address. 5. Once completed with the configuration, click the Save Settings button. 9. I forgot my password, or the password prompt always appears when I am saving settings to the Router. Reset the Router to factory default by pressing the Reset button for 10 seconds and then releasing it. If you are still getting prompted for a password when saving settings, then perform the following steps:
1. Access the Routers web-based utility by going to http://192.168.1.1 or the IP address of the Router. Enter the default password admin, and click the Administrations => Management tab. 2. Enter a different password in the Router Password field, and enter the same password in the second field to confirm the password. 3. Click the Save Settings button. 10. I am a PPPoE user, and I need to remove the proxy settings or the dial-up pop-up window. If you have proxy settings, you need to disable these on your computer. Because the Router is the gateway for the Internet connection, the computer does not need any proxy settings to gain access. Please follow these directions to verify that you do not have any proxy settings and that the browser you use is set to connect directly to the LAN.
For Microsoft Internet Explorer 5.0 or higher:
1. Click Start, Settings, and Control Panel. Double-click Internet Options. 2. Click the Connections tab. 3. Click the LAN settings button and remove anything that is checked. 4. Click the OK button to go back to the previous screen. 5. Click the option Never dial a connection. This will remove any dial-up pop-ups for PPPoE users.
For Netscape 4.7 or higher:
1. Start Netscape Navigator, and click Edit, Preferences, Advanced, and Proxies. 2. Make sure you have Direct connection to the Internet selected on this screen. 3. Close all the windows to finish. Appendix A: Troubleshooting Common Problems and Solutions 47 Compact Wireless-G Broadband Router 11. To start over, I need to set the Router to factory default. Hold the Reset button for 8 seconds and then release it. This will return the password, forwarding, and other settings on the Router to the factory default settings. In other words, the Router will revert to its original factory configuration. 12. I need to upgrade the firmware. In order to upgrade the firmware with the latest features, you need to go to the Linksys website and download the latest firmware at www.linksys.com. Follow these steps:
1. Go to the Linksys website at www.linksys.com and download the latest firmware. 2. To upgrade the firmware, follow the steps in Appendix C: Upgrading Firmware. 13. The firmware upgrade failed, and/or the Power LED is flashing. The upgrade could have failed for a number of reasons. Follow these steps to upgrade the firmware and/or make the Power LED stop flashing:
If the firmware upgrade failed, use the TFTP program (it was downloaded along with the firmware). Open the pdf that was downloaded along with the firmware and TFTP program, and follow the pdfs instructions.
Set a static IP address on the PC; refer to Problem #1, I need to set a static IP address. Use the following IP address settings for the computer you are using:
IP Address: 192.168.1.50 Subnet Mask: 255.255.255.0 Gateway: 192.168.1.1
Perform the upgrade using the TFTP program or the Administration tab of the Routers web-based utility. 14. My DSL services PPPoE is always disconnecting. PPPoE is not actually a dedicated or always-on connection. The DSL ISP can disconnect the service after a period of inactivity, just like a normal phone dial-up connection to the Internet.
There is a setup option to keep alive the connection. This may not always work, so you may need to re-
establish connection periodically. 1. To connect to the Router, go to the web browser, and enter http://192.168.1.1 or the IP address of the Router. 2. Enter the password, if asked. (The default password is admin.) 3. On the Setup screen, select the option Keep Alive, and set the Redial Period option at 20 (seconds). 4. Click the Save Settings button. 5. Click the Status tab, and click the Connect button. 6. You may see the login status display as Connecting. Press the F5 key to refresh the screen, until you see the login status display as Connected.
Click the Save Settings button to continue.
If the connection is lost again, follow steps 1- 6 to re-establish connection. Appendix A: Troubleshooting Common Problems and Solutions 48 Compact Wireless-G Broadband Router 15. I cant access my e-mail, web or I am getting corrupted data from the Internet. The Maximum Transmission Unit (MTU) setting may need to be adjusted. By default, the MTU is set at 1500. For most DSL users, it is strongly recommended to use MTU 1492.
If you are having some difficulties, perform the following steps:
1. To connect to the Router, go to the web browser, and enter http://192.168.1.1 or the IP address of the Router. 2. Enter the password, if asked. (The default password is admin.) 3. Look for the MTU option, and select Manual. In the Size field, enter 1492. 4. Click the Save Settings button to continue.
If your difficulties continue, change the Size to different values. Try this list of values, one value at a time, in this order, until your problem is solved:
1462 1400 1362 1300 16. The Power LED keeps flashing. The Power LED flashes when the device is first powered up. Meantime, the system will boot up itself and check for proper operation. After finishing the checking procedure, the LED stays solid to show that the system is working fine. If the LED keeps flashing after this time, the device is not working properly. Try to flash the firmware by assigning a static IP address to the computer, and then upgrade the firmware. Try using the following settings, IP Address: 192.168.1.50 and Subnet Mask: 255.255.255.0. 17. When I enter a URL or IP address, I get a time-out error or am prompted to retry.
Check if other PCs work. If they do, ensure that your workstations IP settings are correct (IP Address, Subnet Mask, Default Gateway, and DNS). Restart the computer that is having a problem.
If the PCs are configured correctly, but still not working, check the Router. Ensure that it is connected and powered on. Connect to it and check its settings. (If you cannot connect to it, check the LAN and power connections.)
If the Router is configured correctly, check your Internet connection (DSL/cable modem, etc.) to see if it is working correctly. You can remove the Router to verify a direct connection.
Manually configure the TCP/IP settings with a DNS address provided by your ISP.
Make sure that your browser is set to connect directly and that any dial-up is disabled. For Internet Explorer, click Tools, Internet Options, and then the Connection tab. Make sure that Internet Explorer is set to Never dial a connection. For Netscape Navigator, click Edit, Preferences, Advanced, and Proxy. Make sure that Netscape Navigator is set to Direct connection to the Internet. Appendix A: Troubleshooting Common Problems and Solutions 49 Compact Wireless-G Broadband Router Frequently Asked Questions What is the maximum number of IP addresses that the Router will support?
The Router will support up to 253 IP addresses. Is IPSec Pass-Through supported by the Router?
Yes, it is a built-in feature that the Router automatically enables. Where is the Router installed on the network?
In a typical environment, the Router is installed between the cable/DSL modem and the LAN. Plug the Router into the cable/DSL modems Ethernet port. Does the 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 networks, can be used for LAN to LAN connections, but those protocols cannot connect from the Internet to a LAN. Does the Internet connection of the Router support 100Mbps Ethernet?
The Routers current hardware design supports up to 100Mbps Ethernet on its Internet port; however, the Internet connection speed will vary depending on the speed of your broadband connection. The Router also supports 100Mbps over 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 Router to be used with low cost Internet accounts, such as DSL or cable modems, when 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 Router support any operating system other than Windows 98SE, Windows Millennium, Windows 2000, or Windows XP?
Yes, but Linksys does not, at this time, provide technical support for setup, configuration or troubleshooting of any non-Windows operating systems. Does the Router support ICQ send file?
Yes, with the following fix: click ICQ menu -> preference -> connections tab->, and check I am behind a firewall or proxy. Then set the firewall time-out to 80 seconds in the firewall setting. The Internet user can then send a file to a user behind the Router. Appendix A: Troubleshooting Frequently Asked Questions 50 Compact Wireless-G Broadband Router I set up 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. You can also use a port forwarding range of 7777 ~ 27900. If you want to use the UT Server Admin, forward another port.
(Port 8080 usually works well but is used for remote admin. You may have to disable this.) 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 simultaneously with just one public IP address?
It depends on 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 Fortress to work with the Router?
The default client port for Half-Life is 27005. The computers on your LAN need to have +clientport 2700x added 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 wont 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 address of the server computer. How can I block corrupted FTP downloads?
If you are experiencing corrupted files when you download a file with your FTP client, try using another FTP program. The web page hangs; downloads are corrupt, or nothing but junk characters are being displayed on the screen. What do I need to do?
Force your Ethernet adapter to 10Mbps or half duplex mode, and turn off the Auto-negotiate feature of your Ethernet adapter as a temporary measure. (Please look at the Network Control Panel in your Ethernet adapters Advanced Properties tab.) Make sure that your proxy setting is disabled in the browser.

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 static IP if you want to use DMZ Hosting. To get the LAN IP address, see Appendix E: Finding the MAC Address and IP Address for Your Ethernet Adapter. If DMZ Hosting 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. 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. What are the advanced features of the Router?
The Routers advanced features include Advanced Wireless settings, Internet Access Policies, and Port Range Forwarding. Appendix A: Troubleshooting Frequently Asked Questions 52 Compact Wireless-G Broadband Router How do I get mIRC to work with the Router?
Under the Port Forwarding tab, set port forwarding to 113 for the PC on which you are using mIRC. Can the Router act as my DHCP server?
Yes. The Router has DHCP server software built-in. Can I run an application from a remote computer over the wireless network?
This will depend on whether or not the application is designed to be used over a network. Consult the applications documentation to determine if it supports operation over a network. What is the IEEE 802.11a standard?
It is one of the IEEE standards for wireless networks. The 802.11a standard allows wireless networking hardware from different manufacturers to communicate, provided that the hardware complies with the 802.11a standard. The 802.11a standard states a maximum data transfer rate of 54Mbps and an operating frequency of 5GHz. What is the IEEE 802.11b standard?

Multi-Channel Roaming
Automatic Rate Selection
RTS/CTS feature
Fragmentation
Power Management What is ad-hoc mode?
When a wireless network is set to ad-hoc mode, the wireless-equipped computers are configured to communicate directly with each other. The ad-hoc wireless network will not communicate with any wired network. What is infrastructure mode?
When a wireless network is set to infrastructure mode, the wireless network is configured to communicate with a wired network through a wireless access point. What is roaming?
Roaming is the ability of a portable computer to communicate continuously while moving freely throughout an area greater than that covered by a single access point. Before using the roaming function, the user must make sure that the workstation uses the same channel number as the access point of the dedicated coverage area. To achieve true seamless connectivity, the wireless LAN must incorporate a number of different functions. Each node and access point, for example, must always acknowledge receipt of each message. Each node must maintain contact with the wireless network even when not actually transmitting data. Achieving these functions simultaneously requires a dynamic RF networking technology that links access points and nodes. In such a system, the users end node undertakes a search for the best possible access to the system. First, it evaluates such factors as signal strength and quality, as well as the message load currently being carried by each access point and the distance of each access point to the wired backbone. Based on that information, the node next Appendix A: Troubleshooting Frequently Asked Questions 54 Compact Wireless-G Broadband Router selects the right access point and registers its address. Communications between end node and host computer can then be transmitted up and down the backbone. As the user moves on, the end nodes RF transmitter regularly checks the system to determine whether it is in touch with the original access point or whether it should seek a new one. When a node no longer receives acknowledgment from its original access point, it undertakes a new search. Upon finding a new access point, it then re-registers, and the communication process continues. What is ISM band?
The FCC and their counterparts outside of the U.S. have set aside bandwidth for unlicensed use in the ISM
(Industrial, Scientific and Medical) band. Spectrum in the vicinity of 2.4 GHz, in particular, is being made available worldwide. This presents a truly revolutionary opportunity to place convenient high-speed wireless capabilities in the hands of users around the globe. What is Spread Spectrum?
Spread Spectrum technology is a wideband radio frequency technique developed by the military for use in reliable, secure, mission-critical communications systems. It is designed to trade off bandwidth efficiency for reliability, integrity, and security. In other words, more bandwidth is consumed than in the case of narrowband transmission, but the trade-off produces a signal that is, in effect, louder and thus easier to detect, provided that the receiver knows the parameters of the spread-spectrum signal being broadcast. If a receiver is not tuned to the right frequency, a spread-spectrum signal looks like background noise. There are two main alternatives, Direct Sequence Spread Spectrum (DSSS) and Frequency Hopping Spread Spectrum (FHSS). What is DSSS? What is FHSS? And what are their differences?
Frequency-Hopping Spread-Spectrum (FHSS) uses a narrowband carrier that changes frequency in a pattern that is known to both transmitter and receiver. Properly synchronized, the net effect is to maintain a single logical channel. To an unintended receiver, FHSS appears to be short-duration impulse noise. Direct-Sequence Spread-
Spectrum (DSSS) generates a redundant bit pattern for each bit to be transmitted. This bit pattern is called a chip
(or chipping code). The longer the chip, the greater the probability that the original data can be recovered. Even if one or more bits in the chip are damaged during transmission, statistical techniques embedded in the radio can recover the original data without the need for retransmission. To an unintended receiver, DSSS appears as low power wideband noise and is rejected (ignored) by most narrowband receivers. What is WEP?
WEP is Wired Equivalent Privacy, a data privacy mechanism based on a 64-bit or 128-bit shared key algorithm, as described in the IEEE 802.11 standard. What is a MAC Address?
The Media Access Control (MAC) address is a unique number assigned by the manufacturer to any Ethernet networking device, such as a network adapter, that allows the network to identify it at the hardware level. For all Appendix A: Troubleshooting Frequently Asked Questions 55 Compact Wireless-G Broadband Router practical purposes, this number is usually permanent. Unlike IP addresses, which can change every time a computer logs onto the network, the MAC address of a device stays the same, making it a valuable identifier for the network. How do I reset the Router?
Turn the stand on the bottom panel, press the Reset button, and hold in for about eight seconds. This will reset the Router to its default settings. How do I resolve issues with signal loss?
There is no way to know the exact range of your wireless network without testing. Every obstacle placed between the Router and a wireless PC will create signal loss. Lead glass, metal, concrete floors, water and walls will inhibit the signal and reduce range. Start with the Router and your wireless PC in the same room and move it away in small increments to determine the maximum range in your environment. You may also try using different channels, as this may eliminate interference affecting only one channel. If your questions are not addressed here, refer to the Linksys website, www.linksys.com. Appendix A: Troubleshooting Frequently Asked Questions 56 Compact Wireless-G Broadband Router Appendix B: Wireless Security Linksys wants to make wireless networking as safe and easy for you as possible. The current generation of Linksys products provide several network security features, but they require specific action on your part for implementation. So, keep the following in mind whenever you are setting up or using your wireless network. Security Precautions The following is a complete list of security precautions to take (at least steps 1 through 5 should be followed):
1. Change the default SSID. 2. Disable SSID Broadcast. 3. Change the default password for the Administrator account. 4. Enable MAC Address Filtering. 5. Change the SSID periodically. 6. Use the highest encryption algorithm possible. Use WPA if it is available. Please note that this may reduce your network performance. 7. Change the WEP encryption keys periodically. For information on implementing these security features, refer to Chapter 5: Configuring the Compact Wireless-
G Broadband Router. Security Threats Facing Wireless Networks Wireless networks are easy to find. Hackers know that in order to join a wireless network, wireless networking products first listen for beacon messages. These messages can be easily decrypted and contain much of the networks information, such as the networks SSID (Service Set Identifier). Here are the steps you can take:
Change the administrators password regularly. With every wireless networking device you use, keep in mind that network settings (SSID, WEP keys, etc.) are stored in its firmware. Your network administrator is the only person who can change network settings. If a hacker gets a hold of the administrators password, he, too, can change those settings. So, make it harder for a hacker to get that information. Change the administrators password regularly. Appendix B: Wireless Security Security Precautions NOTE: Some of these security features are available only through the network router or access point. Refer to the router or access points documentation for more information. 57 Compact Wireless-G Broadband Router SSID. There are several things to keep in mind about the SSID:
1. Disable Broadcast 2. Make it unique 3. Change it often Most wireless networking devices will give you the option of broadcasting the SSID. While this option may be more convenient, it allows anyone to log into your wireless network. This includes hackers. So, dont broadcast the SSID. Wireless networking products come with a default SSID set by the factory. (The Linksys default SSID is linksys.) Hackers know these defaults and can check these against your network. Change your SSID to something unique and not something related to your company or the networking products you use. Change your SSID regularly so that any hackers who have gained access to your wireless network will have to start from the beginning in trying to break in. MAC Addresses. Enable MAC Address filtering. MAC Address filtering will allow you to provide access to only those wireless nodes with certain MAC Addresses. This makes it harder for a hacker to access your network with a random MAC Address. WEP Encryption. Wired Equivalent Privacy (WEP) is often looked upon as a cure-all for wireless security concerns. This is overstating WEPs ability. Again, this can only provide enough security to make a hackers job more difficult. There are several ways that WEP can be maximized:
1. Use the highest level of encryption possible 2. Use Shared Key authentication 3. Change your WEP key regularly WPA. Wi-Fi Protected Access (WPA) is the newest and best available standard in Wi-Fi security. WPA2 is the newer version of Wi-Fi Protected Access with stronger encryption than WPA. WPA gives you a choice of two encryption methods: TKIP (Temporal Key Integrity Protocol), which utilizes a stronger encryption method and incorporates Message Integrity Code (MIC) to provide protection against hackers, and AES (Advanced Encryption System), which utilizes a symmetric 128-Bit block data encryption. IMPORTANT: Always remember that each device in your wireless network MUST use the same encryption method and encryption key or your wireless network will not function properly. Appendix B: Wireless Security Security Threats Facing Wireless Networks 58 Compact Wireless-G Broadband Router WPA Personal. Select the type of algorithm, TKIP or AES, enter a password in the Passphrase field of 8-64 characters, and enter a Group Key Renewal period time between 0 and 99,999 seconds, which instructs the Router or other device how often it should change the encryption keys. WPA2 Personal. WPA2 gives you one encryption method, AES, with dynamic encryption keys. Enter a Passphrase of 8-63 characters. Then enter a Group Key Renewal period, which instructs the Router how often it should change the encryption keys. WPA2 Mixed Mode. WPA2 Mixed Mode gives you TKIP+AES encryption. Enter a Passphrase of 8-63 characters. Then enter a Group Key Renewal period, which instructs the Router how often it should change the encryption keys. Implementing encryption may have a negative impact on your networks performance, but if you are transmitting sensitive data over your network, encryption should be used. These security recommendations should help keep your mind at ease while you are enjoying the most flexible and convenient technology Linksys has to offer. Appendix B: Wireless Security Security Threats Facing Wireless Networks 59 Compact Wireless-G Broadband Router Appendix C: Upgrading Firmware The Broadband Router's firmware is upgraded through the Web-based Utility's Administration tab.
