The Internet or WAN IP Address can be found on the Status screen of the Router’s web-based utility. For example, if your Internet or WAN IP address is 1.2.3.4, you would enter ping 1.2.3.4 and press the Enter key.• If you get a reply, the computer is connected to the Router.• If you do NOT get a reply, try the ping command from a different computer to verify that your original computer is not the cause of the problem.D In the command prompt, type ping www.yahoo.com and press the Enter key. • If you get a reply, the computer is connected to the Internet. If you cannot open a webpage, try the ping command from a different computer to verify that your original computer is not the cause of the problem.• If you do NOT get a reply, there may be a problem with the connection. Try the ping command from a different computer to verify that your original computer is not the cause of the problem.4. I am not getting an IP address on the Internet with my Internet connection.• Refer to “Problem #3, I want to test my Internet connection” to verify that you have connectivity.• If you need to register the MAC address of your Ethernet adapter with your ISP, please see “Appendix E: Finding the MAC address and IP Address for Your Ethernet Adapter.” If you need to clone the MAC address of your Ethernet adapter onto the Router, see the System section of “Chapter 6: Configuring the Wireless-G Broadband Router” for details.• Make sure you are using the right Internet connection settings. Contact your ISP to see if your Internet connection type is DHCP, Static IP Address, or PPPoE (commonly used by DSL consumers). Please refer to the Setup section of “Chapter 6: Configuring the Wireless-G Broadband Router” for details on Internet connection settings.• Make sure you have the right cable. Check to see if the Internet column has a solidly lit Link/Act LED. • Make sure the cable connecting from your cable or DSL modem is connected to the Router’s Internet port. 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.
62Appendix A: TroubleshootingCommon Problems and SolutionsWireless-G Broadband Router5. 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:When you have completed the configuration, click the Save Settings button.Application Start and End Protocol IP Address EnabledWeb server 80 to 80 Both 192.168.1.100 XFTP server 21 to 21 TCP 192.168.1.101 XSMTP (outgoing) 25 to 25 Both 192.168.1.102 XPOP3 (incoming) 110 to 110 Both 192.168.1.102 X
63Appendix A: TroubleshootingCommon Problems and SolutionsWireless-G Broadband Router7. 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: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.)
