• Your computer may not recognize any DNS server addresses. A DNS server is a host on the Internet that translates Internet names (such as www addresses) to numeric IP addresses. Typically your ISP will provide the addresses of one or two DNS servers for your use. If you entered a DNS address during the router’s configuration, restart your computer. Alternatively, you can configure your computer manually with DNS addresses, as explained in the documentation for your computer. • Your computer may not have the router configured as its default gateway. Reboot the computer and verify the router address (is listed by your computer as the default gateway address. Restoring the Default Configuration and Password This section explains how to restore the factory default configuration settings, changing the router’s administration password to password and the IP address to You can erase the current configuration and restore factory defaults. To restore the factory default configuration settings, use the Default Reset button on the rear panel of the router. 1.

Release the reset button and wait for the router to reboot. Troubleshooting v1.0, April 2007 Router Setup Manual Advanced Troubleshooting Using the Ping Utility Most computers and routers have a diagnostic utility called ping that sends an request to a target device. The device then replies. The ping utility makes it easy to troubleshoot a network. Testing the Path from a PC to Your Router You can ping the router to verify that the LAN path from your computer to your router is set up correctly. 1. From the Windows toolbar, click Start and select Run. 2. In the field provided, type Ping followed by the address of the router, as in this example: ping 3. Click OK. You should see a message like this one: Pinging with 32 bytes of data If the path is working, you see this message: Reply from bytes=32 time=NN ms TTL=xxx If the path is not working, you see this message: Request timed out If the path is not functioning correctly, you could have one of the following problems: • Wrong physical connections — Make sure the LAN port light is on. If the light is off, follow the instructions in “LAN or Internet Port Lights Not On” on page 2-3. — Check that the corresponding lights are on for your computer’s network interface card. • Wrong network configuration — Verify that the Ethernet card driver software and TCP/IP software are both installed and configured on your computer.

If the path is functioning correctly, replies as in the previous section are displayed. If you do not receive replies: — Check that your PC has the IP address of your router listed as the default gateway. If the IP configuration of your PC is assigned by DHCP, this information will not be visible in your PC’s Network Control Panel. Verify that the IP address of the router is listed as the TCP/IP default gateway. — Check to see that the network address of your PC (the portion of the IP address specified by the netmask) is different from the network address of the remote device. — If your ISP assigned a host name to your PC, enter that host name as the Account Name in the Basic Settings menu.
