The 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 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 Wireless-G Broadband Router, this access can be shared over the four switched ports or via the wireless broadcast at up to 11Mbps for Wireless-B or up to 54Mbps for Wireless-G. Use the WPA standard to secure your wireless network while the whole network is protected through a Stateful Packet Inspection (SPI) firewall and Network Address Translation (NAT) technology. The Routers SecureEasySetup feature makes it a snap to set up WPA when you have other SecureEasySetup devices notebooks, printers, other peripheralscomprising your network. Run the Setup Wizard and it will guide you through the steps. You can also access the Routers features 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 Wireless-G Broadband Router bridges wireless networks of both 802.11b and 802.11g standards and wired networks, allowing them to communicate with each other. With your networks all connected, wired, wireless, and the Internet, you can now share files and Internet accessand even play games. All the while, the 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 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 Wireless-G Broadband Router. Chapter 1: Introduction Welcome wpa (wi-fi protected access): a wireless security protocol using TKIP (Temporal Key Integrity Protocol) encryption, which can be used in conjunction with a RADIUS server. spi (stateful packet inspection) firewall: a technology that inspects incoming packets of information before allowing them to enter the network. firewall: Security measures that protect the resources of a local network from intruders. nat (network address translation): NAT technology translates IP addresses of a local area network to a different IP address for the Internet. lan (local area network): The computers and networking products that make up the network in your home or office. 1 Wireless-G Broadband Router Whats in this User Guide?

Wireless-G Broadband Router with SpeedBooster
For DSL users - 1) Make sure you have typed in your user name and password correctly. Some service providers use your full email address as the user name. If you are sure you have enter the right user name, try using username@[isp.com], where isp.com is the name of your service provider. 2) Power down your DSL Modem, your PC, and your router. Then power on your DSL Modem, wait for the LEDs on the DSL modem to stop flashing. Power on your router and wait for the power LED to stop flashing. Finally, power on your PC. 20. My wireless-G speed seems to be slow.
Reposition the antenna.
Reposition the router so that it's higher up, above your other networking gear.
Change CTS Protection to Disable under advanced wireless settings. 21. I do not see a speed improvement while surfing wirelessly with my SpeedBooster equipment.
Your Internet connection is usually much slower than your wireless network with SpeedBooster equipment. This equipment will not affect the speed of your Internet connection.
You will see the most improvements in transferring or streaming files from one computer to another in your network.
Your network speed will slow down if you have mixed 802.11g and SpeedBooster clients. For maximum performance, use all SpeedBooster devices on your network. 22. How do I turn on SpeedBooster on my router?
SpeedBooster is automatically turned on in Mixed and G-Only Mode. There's nothing you need to do to utilize this feature. Appendix A: Troubleshooting Common Problems and Solutions 91 Wireless-G Broadband Router with SpeedBooster Frequently Asked Questions After using SecureEasySetup, my existing wireless devices can no longer connect to the Router. SecureEasySetup uses WPA-Personal encryption. If your current wireless devices do not support WPA-Personal security, then you cannot use SecureEasySetup on your network. You will need to manually configure your network security using the encryption supported by your existing devices. Re-run the Setup Wizard. On the Welcome screen for the Setup Wizard, click Click Here to Start and follow the on-screen instructions. On the Configure Wireless Settings screen, click Enter Wireless Settings Manually and continue to follow the on-
screen instructions. For more information, refer to Chapter 5: Setting up the Wireless-G Broadband Router. How do I set up additional devices using SecureEasySetup?
Repeat the SecureEasySetup process for each device until all of your devices have been configured. Where is my SecureEasySetup button?
On the Router, the SecureEasySetup button is located on the front panel. The button should be lighted either orange or white. For other SecureEasySetup devices, refer to each wireless device's documentation to locate the button on that device. I have devices that support WPA-Personal security, but do not have SecureEasySetup. Can I still use SecureEasySetup?
Yes. Print out the wireless security settings at the end of the SecureEasySetup process, and then manually configure the settings for your non-SecureEasySetup devices. Refer to each wireless devices documentation for instructions on how to enter these settings. 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. Appendix A: Troubleshooting Frequently Asked Questions 92 Wireless-G Broadband Router with SpeedBooster 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. 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 Appendix A: Troubleshooting Frequently Asked Questions 93 Wireless-G Broadband Router with SpeedBooster 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. 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 until the Power LED fully turns on and off. 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 the 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 be downloaded for free. To upgrade the Routers firmware, use the System tab of the Routers web-based utility. If the Routers Internet connection is working well, there is no need to download a newer firmware version, unless that version contains new features that you would like to use. Downloading a more current version of Router firmware will not enhance the quality or speed of your Internet connection, and may disrupt your current connection stability. Will the Router function in a Macintosh environment?
Yes, but the Routers setup pages are accessible only through Internet Explorer 4.0 or Netscape Navigator 4.0 or higher for Macintosh. 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, and make sure that your browser is set to connect directly and that any dial-up is disabled. 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 Frequently Asked Questions 94 Wireless-G Broadband Router with SpeedBooster What is DMZ Hosting?
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, Filters, Port Forwarding, Routing, and DDNS. 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 802.11g standard?
It is one of the IEEE standards for wireless networks. The 802.11g standard allows wireless networking hardware from different manufacturers to communicate, provided that the hardware complies with the 802.11g standard. The 802.11g standard states a maximum data transfer rate of 54Mbps and an operating frequency of 2.4GHz. What IEEE 802.11b features are supported?
The product supports the following IEEE 802.11b functions:
Appendix A: Troubleshooting Frequently Asked Questions 95 Wireless-G Broadband Router with SpeedBooster
CSMA/CA plus Acknowledge protocol
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 user to communicate continuously while moving freely throughout an area greater than that covered by a single access point. Before using the roaming function, the workstation must make sure that it is the same channel number with the access point of 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 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 Appendix A: Troubleshooting Frequently Asked Questions 96 Wireless-G Broadband Router with SpeedBooster 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 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?
Press the Reset button on the back panel for about five seconds. This will reset the Router to its default settings. How do I resolve issues with signal loss?
Appendix A: Troubleshooting Frequently Asked Questions 97 Wireless-G Broadband Router with SpeedBooster 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. I have excellent signal strength, but I cannot see my network. WEP is probably enabled on the Router, but not on your wireless adapter (or vice versa). Verify that the same WEP keys and levels (64 or 128) are being used on all nodes of your wireless network. How many channels/frequencies are available with the Router?
There are eleven available channels, ranging from 1 to 11 (in North America). If your questions are not addressed here, refer to the Linksys website, www.linksys.com. Appendix A: Troubleshooting Frequently Asked Questions 98 Wireless-G Broadband Router with SpeedBooster 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 6: Configuring the 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. 99 Wireless-G Broadband Router with SpeedBooster 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. Two modes are available: Pre-Shared Key and RADIUS. Pre-Shared Key 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. RADIUS (Remote Authentication Dial-In User Service) utilizes a RADIUS server for authentication and the use of dynamic TKIP, AES, or WEP. 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 100 Wireless-G Broadband Router with SpeedBooster
For DSL users - 1) Make sure you have typed in your user name and password correctly. Some service providers use your full email address as the user name. If you are sure you have enter the right user name, try using username@[isp.com], where isp.com is the name of your service provider. 2) Power down your DSL Modem, your PC, and your router. Then power on your DSL Modem, wait for the LEDs on the DSL modem to stop flashing. Power on your router and wait for the power LED to stop flashing. Finally, power on your PC. 20. My wireless-G speed seems to be slow.
Reposition the antenna.
Reposition the router so that it's higher up, above your other networking gear.
Change CTS Protection to Disable under advanced wireless settings. 21. I do not see a speed improvement while surfing wirelessly with my SpeedBooster equipment.
Your Internet connection is usually much slower than your wireless network with SpeedBooster equipment. This equipment will not affect the speed of your Internet connection.
You will see the most improvements in transferring or streaming files from one computer to another in your network.
Your network speed will slow down if you have mixed 802.11g and SpeedBooster clients. For maximum performance, use all SpeedBooster devices on your network. 22. How do I turn on SpeedBooster on my router?
SpeedBooster is automatically turned on in Mixed and G-Only Mode. There's nothing you need to do to utilize this feature. Appendix A: Troubleshooting Common Problems and Solutions 91 Wireless-G Broadband Router with SpeedBooster Frequently Asked Questions After using SecureEasySetup, my existing wireless devices can no longer connect to the Router. SecureEasySetup uses WPA-Personal encryption. If your current wireless devices do not support WPA-Personal security, then you cannot use SecureEasySetup on your network. You will need to manually configure your network security using the encryption supported by your existing devices. Re-run the Setup Wizard. On the Welcome screen for the Setup Wizard, click Click Here to Start and follow the on-screen instructions. On the Configure Wireless Settings screen, click Enter Wireless Settings Manually and continue to follow the on-
screen instructions. For more information, refer to Chapter 5: Setting up the Wireless-G Broadband Router. How do I set up additional devices using SecureEasySetup?
Repeat the SecureEasySetup process for each device until all of your devices have been configured. Where is my SecureEasySetup button?
On the Router, the SecureEasySetup button is located on the front panel. The button should be lighted either orange or white. For other SecureEasySetup devices, refer to each wireless device's documentation to locate the button on that device. I have devices that support WPA-Personal security, but do not have SecureEasySetup. Can I still use SecureEasySetup?
Yes. Print out the wireless security settings at the end of the SecureEasySetup process, and then manually configure the settings for your non-SecureEasySetup devices. Refer to each wireless devices documentation for instructions on how to enter these settings. 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. Appendix A: Troubleshooting Frequently Asked Questions 92 Wireless-G Broadband Router with SpeedBooster 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. 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 Appendix A: Troubleshooting Frequently Asked Questions 93 Wireless-G Broadband Router with SpeedBooster 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. 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 until the Power LED fully turns on and off. 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 the 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 be downloaded for free. To upgrade the Routers firmware, use the System tab of the Routers web-based utility. If the Routers Internet connection is working well, there is no need to download a newer firmware version, unless that version contains new features that you would like to use. Downloading a more current version of Router firmware will not enhance the quality or speed of your Internet connection, and may disrupt your current connection stability. Will the Router function in a Macintosh environment?
Yes, but the Routers setup pages are accessible only through Internet Explorer 4.0 or Netscape Navigator 4.0 or higher for Macintosh. 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, and make sure that your browser is set to connect directly and that any dial-up is disabled. 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 Frequently Asked Questions 94 Wireless-G Broadband Router with SpeedBooster What is DMZ Hosting?
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, Filters, Port Forwarding, Routing, and DDNS. 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 802.11g standard?
It is one of the IEEE standards for wireless networks. The 802.11g standard allows wireless networking hardware from different manufacturers to communicate, provided that the hardware complies with the 802.11g standard. The 802.11g standard states a maximum data transfer rate of 54Mbps and an operating frequency of 2.4GHz. What IEEE 802.11b features are supported?
The product supports the following IEEE 802.11b functions:
Appendix A: Troubleshooting Frequently Asked Questions 95 Wireless-G Broadband Router with SpeedBooster
CSMA/CA plus Acknowledge protocol
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 user to communicate continuously while moving freely throughout an area greater than that covered by a single access point. Before using the roaming function, the workstation must make sure that it is the same channel number with the access point of 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 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 Appendix A: Troubleshooting Frequently Asked Questions 96 Wireless-G Broadband Router with SpeedBooster 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 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?
Press the Reset button on the back panel for about five seconds. This will reset the Router to its default settings. How do I resolve issues with signal loss?
Appendix A: Troubleshooting Frequently Asked Questions 97 Wireless-G Broadband Router with SpeedBooster 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. I have excellent signal strength, but I cannot see my network. WEP is probably enabled on the Router, but not on your wireless adapter (or vice versa). Verify that the same WEP keys and levels (64 or 128) are being used on all nodes of your wireless network. How many channels/frequencies are available with the Router?
There are eleven available channels, ranging from 1 to 11 (in North America). If your questions are not addressed here, refer to the Linksys website, www.linksys.com.

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.

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. Two modes are available: Pre-Shared Key and RADIUS. Pre-Shared Key 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. RADIUS (Remote Authentication Dial-In User Service) utilizes a RADIUS server for authentication and the use of dynamic TKIP, AES, or WEP. 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 100 Wireless-G Broadband Router with SpeedBooster WPA Pre-Shared Key. If you do not have a RADIUS server, Select the type of algorithm, TKIP or AES, enter a password in the Pre-Shared key 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. WPA RADIUS. WPA used in coordination with a RADIUS server. (This should only be used when a RADIUS server is connected to the Router or other device.) First, select the type of WPA algorithm, TKIP or AES. Enter the RADIUS servers IP Address and port number, along with a key shared between the device and the server. Last, enter a Group Key Renewal period, which instructs the device how often it should change the encryption keys. RADIUS. WEP used in coordination with a RADIUS server. (This should only be used when a RADIUS server is connected to the Router or other device.) First, enter the RADIUS servers IP Address and port number, along with a key shared between the device and the server. Then, select a WEP key and a level of WEP encryption, and either generate a WEP key through the Passphrase or enter the WEP key manually. 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.

Wireless-G Broadband Router with SpeedBooster Chapter 1: Introduction Welcome Thank you for choosing the Linksys Wireless-G Broadband Router with SpeedBooster. The Wireless-G Broadband Router with SpeedBooster will allow you to network wirelessly better than ever, sharing Internet access, files and fun, easily and securely. How does the Wireless-G Broadband Router with SpeedBooster do all of this? A router is a device that allows access to an Internet connection over a network. With the Wireless-G Broadband Router with SpeedBooster, this access can be shared over the four switched ports or via the wireless network, broadcast at either 11Mbps for Wireless-B or 54Mbps for Wireless-G. In addition, WEP encryption provides greater security opportunities while the whole network is protected through a Stateful Packet Inspection (SPI) firewall and NAT technology. All of these security features, as well as full configurability, are accessed 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 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. The Wireless-G Broadband Router with SpeedBooster bridges wireless networks of both 802.11b and 802.11g standards and wired networks, allowing them to communicate with each other. And since this Router has SpeedBooster technology, your wireless network performance increases by up to 30% from old 802.11g standards. In fact, even non-SpeedBooster-equipped devices on your network will see a speed improvement when communicating with SpeedBooster-enhanced equipment!
With your networks all connected, wired, wireless, and the Internet, you can now share files and Internet accessand even play games. All the while, the Wireless-G Broadband Router with SpeedBooster protects your networks from unauthorized and unwelcome users. You should always use the Setup CD-ROM when you first install 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 Wireless-G Broadband Router with SpeedBooster, 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 Wireless-G Broadband Router with SpeedBooster. 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 802.11b: an IEEE wireless networking standard that specifies a maximum data transfer rate of 11Mbps and an operating frequency of 2.4GHz. 802.11b: 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 Wireless-G Broadband Router with SpeedBooster Chapter 2: Planning Your Wireless Network Network Topology A wireless local area network is exactly like a regular local area network (LAN), except that each computer in the wireless network uses a wireless device to connect to the network. Computers in a wireless network share the same frequency channel and SSID, which is an identification name shared by the wireless devices belonging to the same wireless network. 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 wireless and wired network 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, 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 Wireless-G Broadband Router has been specifically designed for use with both your 802.11b and 802.11g products. Now, products using these standards can communicate with each other. network: a series of computers or devices connected for the purpose of data sharing, storage, and/or transmission between users. ssid: your wireless networks name. ad-hoc: a group of wireless devices communicating directly to each other

Chapter 2: Planning Your Wireless Network Network Topology 4 Wireless-G Broadband Router with SpeedBooster The Wireless-G Broadband Router is compatible with all 802.11b and 802.11g adapters, such as the Notebook Adapters (WPC54G, WPC11) for your laptop computers, PCI Adapter (WMP54G, WMP11) for your desktop PC, and USB Adapter (WUSB54G, WUSB11) when you want to enjoy USB connectivity. The Router will also communicate with the Wireless PrintServer (WPS54GU2, WPS11) and Wireless Ethernet Bridges (WET54G, WET11). When you wish to connect your wireless network with your wired network, you can use the Wireless-G Broadband Routers four LAN ports. To add more ports, any of the Wireless-G Broadband Router's LAN ports can be connected to any of Linksys's switches (such as the EZXS55W or EZXS88W). With these, and many other, Linksys products, your networking options are limitless.

Figure 4-3: Connecting the Power Now that the hardware installation is complete, proceed to Chapter 5: Configuring the Wireless-G Broadband Router, for directions on using the Routers Web-Based Utility to configure the Routers settings for your network. Chapter 4: Connecting the Wireless-G Broadband Router Hardware Installation for Connection to Your Broadband Modem 9 Wireless-G Broadband Router with SpeedBooster Connecting One Router to Another Some applications, such as Parental Control, apply setting to all PCs connected to the Router. Sometimes, you may not want those settings to apply to all settings in your network. When this is the case, you may want to connect the Router behind another, so you can have some PCs connected to the Router with Parental Control and some connected to a Router without. Before you connect one Router to another, you must make sure that both have different IP Addresses. This is mandatory because both routers may be set to the same IP address by default, right out of the box. If both routers have the same IP address, then you may not be able to set up the Router with Parental Control. First, make sure the Router is NOT connected to your network. Then follow these instructions:
1. To access the other routers Web-based Utility, launch Internet Explorer or Netscape Navigator, and enter the other routers default IP address, 192.168.1.1, or whatever IP Address you have set it to, in the Address field. Then, press Enter. 2. A password request page will appear. Leave the User Name field blank. In the Password field, enter the password you have set (the default password is admin). Then click the OK button. 3. The first screen that appears will display the Setup tab. In the Network Setup section, there is a setting called Local IP Address, which is set to 192.168.1.1.

If you choose to enable the Routers DHCP server option, you must configure all of your network PCs to connect to a DHCP server (the Router), and make sure there is no other DHCP server on your network. DHCP Server. DHCP is enabled by factory default. If you already have a DHCP server on your network, or you dont want a DHCP server, then click the Disable radio button (no other DHCP features will be available). Starting IP Address. Enter a value for the DHCP server to start with when issuing IP addresses. Because the Routers default IP address is 192.168.1.1, the Starting IP Address must be 192.168.1.2 or greater, but smaller than 192.168.1.253. The default Starting IP Address is 192.168.1.100. Maximum Number of DHCP Users. Enter the maximum number of PCs that you want the DHCP server to assign IP addresses to. This number cannot be greater than 253. The default is 50. Client Lease Time. The Client Lease Time is the amount of time a network user will be allowed connection to the Router with their current dynamic IP address. Enter the amount of time, in minutes, that the user will be leased this dynamic IP address. After the time is up, the user will be automatically assigned a new dynamic IP address. The default is 0 minutes, which means one day. Static DNS (1-3). The Domain Name System (DNS) is how the Internet translates domain or website names into Internet addresses or URLs. Your ISP will provide you with at least one DNS Server IP Address. If you wish to use another, type that IP Address in one of these fields. You can type up to three DNS Server IP Addresses here. The Router will use these for quicker access to functioning DNS servers. WINS. The Windows Internet Naming Service (WINS) manages each PCs interaction with the Internet. If you use a WINS server, enter that servers IP Address here. Otherwise, leave this blank. Time Setting Change the time zone in which your network functions from this pull-down menu.

Wireless-G Broadband Router Chapter 2: Planning Your Wireless Network ssid (service set identifier): your wireless networks name. infrastructure: a wireless network that is bridged to a wired network via an access point. ad-hoc: a group of wireless devices communicating directly to each other (peer-to-
peer) without the use of an access point. 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. 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 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 Wireless-G Broadband Router has been specifically designed for use with both your 802.11b and 802.11g products. Now, products using these standards can communicate with each other. Chapter 2: Planning Your Wireless Network Network Topology 4 Wireless-G Broadband Router The Wireless-G Broadband Router is compatible with all 802.11b and 802.11g adapters, such as the Notebook Adapters (WPC54G, WPC11) for your laptop computers, PCI Adapter (WMP54G, WMP11) for your desktop PC, and USB Adapter (WUSB54G, WUSB11) when you want to enjoy USB connectivity. The Broadband Router will also communicate with the Wireless PrintServer (WPS54G) and Wireless Ethernet Bridges (WET54G, WET11). When you wish to connect your wireless network with your wired network, you can use the Wireless-G Broadband Routers four LAN ports. To add more ports, any of the Wireless-G Broadband Router's LAN ports can be connected to any of Linksys's switches (such as the SD205 or SD208). With these, and many other, Linksys products, your networking options are limitless. Go to the Linksys website at www.linksys.com for more information about products that work with the Wireless-G Broadband Router. Chapter 2: Planning Your Wireless Network Network Layout 5 Wireless-G Broadband Router Chapter 3: Getting to Know the Wireless-G Broadband Router The Back Panel The Router's ports, where the cables are connected, are located on the back panel. Figure 3-1: The Routers Back Panel Reset Button There are two ways to reset the Router's factory defaults. Either press the Reset Button, for approximately five seconds, or restore the defaults from the Administration tab - Factory Defaults in the Router's Web-based Utility. Internet 1, 2, 3, 4 The Internet port is where you will connect your broadband Internet connection. These ports (1, 2, 3, 4) connect the Router to your networked PCs and other Ethernet network devices. Power The Power port is where you will connect the power adapter. IMPORTANT: Resetting the Router will erase all of your settings (Internet connection, wireless security, and other settings) and replace them with the factory defaults. Do not reset the Router if you want to retain these settings. Chapter 3: Getting to Know the Wireless-G Broadband Router The Back Panel 6 Wireless-G Broadband Router The Front Panel The Routers SecureEasySetup button (the Cisco logo) and LEDs are located on the front panel. Figure 3-2: The Routers Front Panel
(Cisco logo) Power DMZ WLAN 1, 2, 3, 4 Orange/White. The Cisco logo is the Routers SecureEasySetup button. It lights up and will stay orange when the Router is powered on. The color orange indicates that the Router is not using the SecureEasySetup feature, while the color white indicates that the Router is using the SecureEasySetup feature. When the Router enters SecureEasySetup mode, the Cisco logo will turn white and start flashing. After the Router has generated the SSID and WPA-PSK (also called WPA-Personal) key, the Cisco logo will stop flashing and stay white. To clear the SSID and WPA-PSK key, press and hold down the Cisco logo for five seconds. The Cisco logo will flash slowly as the Router resets itself. The Cisco logo will turn orange to indicate a successful reset. Green. The Power LED lights up and will stay on while the Router is powered on. When the Router goes through its self-diagnostic mode during every boot-up, this LED will flash. When the diagnostic is complete, the LED will be solidly lit. Green. The DMZ LED indicates when the DMZ function is being used. This LED will remain lit as long as DMZ is enabled. Green. The WLAN LED lights up whenever there is a successful wireless connection. If the LED is flashing, the Router is actively sending or receiving data over the network. Green. These numbered LEDs, corresponding with the numbered ports on the Routers back panel, serve two purposes. If the LED is continuously lit, the Router is successfully connected to a device through that port. A flashing LED indicates network activity over that port. Internet Green. The Internet LED lights up when there is a connection made through the Internet port. NOTE: SecureEasySetup is a feature that makes it easy to set up your wireless network. If you have SecureEasySetup devices, run the Routers Setup Wizard CD-ROM and follow the on-screen instructions to use SecureEasySetup. Chapter 3: Getting to Know the Wireless-G Broadband Router The Front Panel 7 Wireless-G Broadband Router Chapter 4: Connecting the Wireless-G Broadband Router Overview This chapter includes two sets of instructions. If the Wireless-G Broadband Router will be the only router in your network, follow the instructions in Hardware Installation for Connection to Your Broadband Modem. If you want to install the Wireless-G Broadband Router behind another router in your network, then follow the instructions in Hardware Installation for Connection to Another Router. Hardware Installation for Connection to Your Broadband Modem 1. Power down your network devices. 2. Locate an optimum location for the Router. The best place for the Router is usually at the center of your wireless network, with line of sight to all of your mobile stations. 3. Fix the direction of the antennas. Try to place the Router in a position that will best cover your wireless network. Normally, the higher you place the antenna, the better the performance will be. 4. Connect a standard Ethernet network cable to the Routers Internet port. Then, connect the other end of the Ethernet cable to your cable or DSL broadband modem. Figure 4-1: Connecting Your Internet Connection Chapter 4: Connecting the Wireless-G Broadband Router Overview 8 Wireless-G Broadband Router 5.

Chapter 4: Connecting the Wireless-G Broadband Router Hardware Installation for Connection to Your Broadband Modem 9 Wireless-G Broadband Router Hardware Installation for Connection to Another Router Before you install the Router, you must change the default IP address of the other router. This is mandatory because both routers may be set to the same IP address by default. If you do not change the other routers default IP address, then you may not be able to set up the Router. First, make sure the Router is NOT connected to your network. Then follow these instructions:
1. To access the other routers Web-based Utility, launch Internet Explorer or Netscape Navigator, and enter the other routers default IP address, 192.168.1.1, in the Address field. Then press Enter. 2. A password request page will appear. Leave the User Name field blank. In the Password field, enter the password you have set (the default password is admin). Then click the OK button. 3. The first screen that appears will display the Setup tab. In the Network Setup section, there is a setting called Local IP Address, which is set to 192.168.1.1. Change this to 192.168.2.1. 4. Click the Save Settings button to save your change, and then exit the Web-based Utility. 5. Power down your network devices. Now you will begin the hardware installation of Router. 6. Locate an optimum location for the Router. The best place for the Router is usually at the center of your wireless network, with line of sight to all of your mobile stations. 7. Fix the direction of the antennas. Try to place the Router in a position that will best cover your wireless network. Normally, the higher you place the antenna, the better the performance will be. 8. Connect a standard Ethernet network cable to the Routers Internet port. Then, connect the other end of the Ethernet cable to one of the numbered Ethernet ports on your other router. NOTE: Steps 1-4 are instructions for a typical Linksys router; however, if you are using a non-
Linksys router, refer to the other routers documentation for instructions on how to change its local IP address to 192.168.2.1.

Network Address Server Settings (DHCP) The settings allow you to configure the Routers Dynamic Host Configuration Protocol (DHCP) server function. The Router can be used as a DHCP server for your network. A DHCP server automatically assigns an IP address to each computer on your network. If you choose to enable the Routers DHCP server option, you must configure all of your network PCs to connect to a DHCP server (the Router), and make sure there is no other DHCP server on your network. DHCP Server. DHCP is enabled by factory default. If you already have a DHCP server on your network, or you dont want a DHCP server, then click the Disable radio button (no other DHCP features will be available). Starting IP Address. Enter a value for the DHCP server to start with when issuing IP addresses. Because the Routers default IP address is 192.168.1.1, the Starting IP Address must be 192.168.1.2 or greater, but smaller than 192.168.1.253. The default Starting IP Address is 192.168.1.100. Maximum Number of DHCP Users. Enter the maximum number of PCs that you want the DHCP server to assign IP addresses to. This number cannot be greater than 253. The default is 50. Client Lease Time. The Client Lease Time is the amount of time a network user will be allowed connection to the Router with their current dynamic IP address. Enter the amount of time, in minutes, that the user will be leased this dynamic IP address. After the time is up, the user will be automatically assigned a new dynamic IP address. The default is 0 minutes, which means one day. Static DNS (1-3). The Domain Name System (DNS) is how the Internet translates domain or website names into Internet addresses or URLs. Your ISP will provide you with at least one DNS Server IP Address. If you wish to use another, type that IP Address in one of these fields. You can type up to three DNS Server IP Addresses here. The Router will use these for quicker access to functioning DNS servers. WINS. The Windows Internet Naming Service (WINS) manages each PCs interaction with the Internet. If you use a WINS server, enter that servers IP Address here. Otherwise, leave this blank. Time Setting Change the time zone in which your network functions from this pull-down menu.

Wireless-G Broadband Router The Wireless Tab - Advanced Wireless Settings This tab is used to set up the Routers advanced wireless functions. These settings should only be adjusted by an expert administrator as incorrect settings can reduce wireless performance. Authentication Type. The default is set to Auto, which 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. 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. 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 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. CTS Protection Mode. CTS (Clear-To-Send) Protection Mode should remain disabled unless you are having severe problems with your Wireless-G products not being 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. Frame Burst. Enabling this option should provide your network with greater performance, depending on the manufacturer of your wireless products. If you are not sure how to use this option, keep the default, Disable. Beacon Interval. The default value is 100. Enter a value between 1 and 65,535 milliseconds. 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. DTIM Interval. This value, between 1 and 255, 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 6-23: Wireless Tab - Advanced Wireless Settings Chapter 6: Configuring the Wireless-G Broadband Router The Wireless Tab - Advanced Wireless Settings 44 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. 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.

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 61 Wireless-G Broadband Router 5. I am not able to access the Setup page of the Routers web-based utility.
Refer to Problem #3, 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 #2: I need to set a static IP address.
Refer to Problem #10: I am a PPPoE user, and I need to remove the proxy settings or the dial-up pop-up window. 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 Forward tab. 2. Enter any name you want to use for the Application. 3. Enter the Start and End 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. Select the protocol(s) 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 Enable option for the port services you want to use. Consider the example below:
Application Start and End 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 62 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 Forward tab. 2. Enter any name you want to use for the Application. 3. Enter the Start and End 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. Select the protocol(s) 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 Enable option for the port services you want to use. Consider the example below:
Application Start and End 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 63

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 64 Wireless-G Broadband Router 11. To start over, I need to set the Router to factory default. Hold the Reset button for 10 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 http://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 #2, 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 65 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 66 Wireless-G Broadband Router Frequently Asked Questions After using SecureEasySetup, my existing wireless devices can no longer connect to the Router. SecureEasySetup uses WPA-Personal encryption. If your current wireless devices do not support WPA-Personal security, then you cannot use SecureEasySetup on your network. You will need to manually configure your network security using the encryption supported by your existing devices. Re-run the Setup Wizard. On the Welcome screen for the Setup Wizard, click Click Here to Start and follow the on-screen instructions. On the Configure Wireless Settings screen, click Enter Wireless Settings Manually and continue to follow the on-
screen instructions. For more information, refer to Chapter 5: Setting up the Wireless-G Broadband Router. How do I set up additional devices using SecureEasySetup?
Repeat the SecureEasySetup process for each device until all of your devices have been configured. Where is my SecureEasySetup button?
On the Router, the SecureEasySetup button is located on the front panel. The button should be lighted either orange or white. For other SecureEasySetup devices, refer to each wireless device's documentation to locate the button on that device. I have devices that support WPA-Personal security, but do not have SecureEasySetup. Can I still use SecureEasySetup?
Yes. Print out the wireless security settings at the end of the SecureEasySetup process, and then manually configure the settings for your non-SecureEasySetup devices. Refer to each wireless devices documentation for instructions on how to enter these settings. 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. Appendix A: Troubleshooting Frequently Asked Questions 67 Wireless-G Broadband Router 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. 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 Appendix A: Troubleshooting Frequently Asked Questions 68 Wireless-G Broadband Router 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. Check our website at www.linksys.com for more information. If all else fails in the installation, what can I do?

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, filters, access restriction policies, port forwarding, advanced routing, and DDNS. 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 802.11g standard?
It is one of the IEEE standards for wireless networks. The 802.11g standard allows wireless networking hardware from different manufacturers to communicate, provided that the hardware complies with the 802.11g standard. The 802.11g standard states a maximum data transfer rate of 54Mbps and an operating frequency of 2.4GHz. Appendix A: Troubleshooting Frequently Asked Questions 70 Wireless-G Broadband Router What is the IEEE 802.11b standard?

The product supports the following IEEE 802.11b functions:
CSMA/CA plus Acknowledge protocol
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 user to communicate continuously while moving freely throughout an area greater than that covered by a single access point. Before using the roaming function, the workstation must make sure that it is the same channel number with the access point of 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 Appendix A: Troubleshooting Frequently Asked Questions 71 Wireless-G Broadband Router 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 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. Appendix A: Troubleshooting Frequently Asked Questions 72 Wireless-G Broadband Router 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 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?
Press the Reset button on the back panel for about five 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. I have excellent signal strength, but I cannot see my network. Wireless security is probably enabled on the Router, but not on your wireless adapter (or vice versa). Verify that the same wireless security method and passphrase/keys are being used on all devices of your wireless network. How many channels/frequencies are available with the Router?
There are eleven available channels, ranging from 1 to 11, in North America. There may be additional channels available in other regions, subject to the regulations of your region and/or country. If your questions are not addressed here, refer to the Linksys website, www.linksys.com. Appendix A: Troubleshooting Frequently Asked Questions 73 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 6: Configuring the 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. 74 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. Two modes are available: Pre-Shared Key and RADIUS. Pre-Shared Key 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. RADIUS (Remote Authentication Dial-In User Service) utilizes a RADIUS server for authentication and the use of dynamic TKIP, AES, or WEP. 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 75 Wireless-G Broadband Router WPA Pre-Shared Key. If you do not have a RADIUS server, Select the type of algorithm, TKIP or AES, enter a password in the Pre-Shared key 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. WPA RADIUS. WPA used in coordination with a RADIUS server. (This should only be used when a RADIUS server is connected to the Router or other device.) First, select the type of WPA algorithm, TKIP or AES. Enter the RADIUS servers IP Address and port number, along with a key shared between the device and the server. Last, enter a Group Key Renewal period, which instructs the device how often it should change the encryption keys. RADIUS. WEP used in coordination with a RADIUS server. (This should only be used when a RADIUS server is connected to the Router or other device.) First, enter the RADIUS servers IP Address and port number, along with a key shared between the device and the server. Then, select a WEP key and a level of WEP encryption, and either generate a WEP key through the Passphrase or enter the WEP key manually. 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.
