Verify that the Status page of the Router’s web-based utility shows a valid IP address from your ISP. • 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 Router’s web-based utility to see if you get an IP address. Appendix A: Troubleshooting Common Problems and Solutions 40 Wireless-G Broadband Router with RangeBooster 5. I am not able to access the Setup page of the Router’s 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 Router’s web-based utility. We will be setting up web, ftp, and mail servers. 1. Access the Router’s 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 server’s 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 80 to 80 Both 192.168.1.100 FTP server 21 to 21 TCP 192.168.1.101 SMTP (outgoing) 25 to 25 Both 192.168.1.102 POP3 (incoming) 110 to 110 Both 192.168.1.102 When you have completed the configuration, click the Save Settings button. Appendix A: Troubleshooting Common Problems and Solutions 41 Wireless-G Broadband Router with RangeBooster 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 Router’s 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 server’s 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 7777 to 27900 Both 192.168.1.100 Halflife 27015 to 27015 Both 192.168.1.105 PC Anywhere 5631 to 5631 UDP 192.168.1.102 VPN IPSEC 500 to 500 UDP 192.168.1.100 When you have completed the configuration, click the Save Settings button. 8. I can’t 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 42 Wireless-G Broadband Router with RangeBooster Follow these steps to set DMZ hosting: 1. Access the Router’s 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. Disable or remove the entries you have entered for forwarding. Keep this information in case you want to use it at a later time. 3. Go to the Applications & Gaming => DMZ tab. 4. Select Enable next to DMZ. In the Client PC IP Address field, enter the IP address of the computer you want exposed to the Internet. This will bypass the NAT technology for that computer. Please refer to “Appendix E: Finding the MAC Address and IP Address for Your Ethernet Adapter” for details on getting an IP address. 5. Once completed with the configuration, click the Save Settings button. 9. I forgot my password, or the password prompt always appears when I am saving settings to the Router. Reset the Router to factory default by pressing the Reset button for 10 seconds and then releasing it. If you are still getting prompted for a password when saving settings, then perform the following steps: 1. Access the Router’s web-based utility by going to http://192.168.1.1 or the IP address of the Router. Enter the default password admin, and click the Administration => Management tab. 2. Enter a different password in the Router Password field, and enter the same password in the second field to confirm the password. 3. Click the Save Settings button. 10. I am a PPPoE user, and I need to remove the proxy settings or the dial-up pop-up window. If you have proxy settings, you need to disable these on your computer. Because the Router is the gateway for the Internet connection, the computer does not need any proxy settings to gain access. Please follow these directions to verify that you do not have any proxy settings and that the browser you use is set to connect directly to the LAN. • For Microsoft Internet Explorer 5.0 or higher: 1. Click Start, Settings, and Control Panel. Double-click Internet Options. 2. Click the Connections tab. 3. Click the LAN settings button and remove anything that is checked. 4. Click the OK button to go back to the previous screen. 5. Click the option Never dial a connection. This will remove any dial-up pop-ups for PPPoE users. • For Netscape 4.7 or higher: 1. Start Netscape Navigator, and click Edit, Preferences, Advanced, and Proxies. 2. Make sure you have Direct connection to the Internet selected on this screen. 3. Close all the windows to finish. Appendix A: Troubleshooting Common Problems and Solutions 43 Wireless-G Broadband Router with RangeBooster 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 pdf’s 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 Router’s web-based utility. 14. My DSL service’s 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 reestablish 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 44 Wireless-G Broadband Router with RangeBooster 15. I can’t 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 workstation’s 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 45 Wireless-G Broadband Router with RangeBooster 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 onscreen instructions. For more information, refer to “Chapter 5: Setting up the Wireless-G Broadband Router with RangeBooster.” 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 device’s 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 modem’s 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 46 Wireless-G Broadband Router with RangeBooster Does the Internet connection of the Router support 100Mbps Ethernet? The Router’s 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 won’t let multiple computers with the same CD key connect at Appendix A: Troubleshooting Frequently Asked Questions 47 Wireless-G Broadband Router with RangeBooster 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 adapter’s Advanced Properties tab.) Make sure that your proxy setting is disabled in the browser. Check our website at www.linksys.com for more information. If all else fails in the installation, what can I do? Reset the Router by holding down the reset button 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 Router’s firmware, use the Administration - Firmware Upgrade tab of the Router’s web-based utility. If the Router’s 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 Router’s 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 48 Wireless-G Broadband Router with RangeBooster 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 Router’s 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 application’s 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 49 Wireless-G Broadband Router with RangeBooster What is the IEEE 802.11b standard? It is one of the IEEE standards for wireless networks. The 802.11b standard allows wireless networking hardware from different manufacturers to communicate, provided that the hardware complies with the 802.11b standard. The 802.11b standard states a maximum data transfer rate of 11Mbps and an operating frequency of 2.4GHz. What IEEE 802.11g features are supported? The product supports the following IEEE 802.11g functions: • CSMA/CA plus Acknowledge protocol • OFDM protocol • Multi-Channel Roaming • Automatic Rate Selection • RTS/CTS feature • Fragmentation • Power Management What IEEE 802.11b features are supported? 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 50 Wireless-G Broadband Router with RangeBooster 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 user’s 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 node’s 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 SpreadSpectrum (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 51 Wireless-G Broadband Router with RangeBooster 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 52 Wireless-G Broadband Router with RangeBooster 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. NOTE: Some of these security features are available only through the network router or access point. Refer to the router or access point’s documentation for more information. 7. Change the WEP encryption keys periodically. For information on implementing these security features, refer to “Chapter 6: Configuring the Wireless-G Broadband Router with RangeBooster.” 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 network’s information, such as the network’s SSID (Service Set Identifier). Here are the steps you can take: Change the administrator’s 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 administrator’s password, he, too, can change those settings. So, make it harder for a hacker to get that information. Change the administrator’s password regularly. Appendix B: Wireless Security Security Precautions 53 Wireless-G Broadband Router with RangeBooster 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, don’t 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 WEP’s ability. Again, this can only provide enough security to make a hacker’s 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 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. WPA. Wi-Fi Protected Access (WPA) is the newest and best available standard in Wi-Fi security. Two modes are available: WPA Personal and WPA Enterprise. WPA Personal 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. WPA Enterprise uses TKIP or AES encryption and utilizes a RADIUS (Remote Authentication Dial-In User Service) server for authentication. Appendix B: Wireless Security Security Threats Facing Wireless Networks 54 Wireless-G Broadband Router with RangeBooster WPA Personal. Select the type of encryption, TKIP or AES, enter a Passphrase (pre-shared key) of 8-64 characters, and enter a 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 Enterprise. 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 encryption, TKIP or AES. Enter the RADIUS server’s IP Address and port number, along with a key shared between the device and the server. Last, enter a 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 server’s IP Address and port number, along with a shared secret (authentication 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. Then, select a Tx key. Implementing encryption may have a negative impact on your network’s 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.
