Troubleshooting Internet Browsing
If your router can obtain an IP address but your computer is unable to load any Web pages from the Internet:
•The Traffic meter is enabled and the limit might have been reached.
By configuring the traffic meter to not block, you can resume Internet access. If you have an usage limit, your ISP may charge you for the overage.
•Your computer might 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 provides the addresses of one or two DNS servers for your use. If you entered a DNS address during the router’s configuration, reboot your computer and verify the DNS address as described in "Internet Networking and TCP/IP Addressing:" in Appendix B. Alternatively, you can configure your computer manually with DNS addresses, as explained in your operating system documentation.
•Your computer might not have the router configured as its TCP/IP router.
If your computer obtains its information from the router by DHCP, reboot the computer, and verify the router address as described in the link to the online document "Internet Networking and TCP/IP Addressing:" in Appendix B.
Troubleshooting a TCP/IP Network Using the Ping Utility
Most TCP/IP terminal devices and routers contain a ping utility that sends an echo request packet to the designated device. The device then responds with an echo reply. Troubleshooting a TCP/IP network is made very easy by using the ping utility in your computer.
Testing the LAN Path to Your Router
You can ping the router from your PC to verify that the LAN path to your router is set up correctly.
To ping the router from a PC running Windows 95 or later:
1.From the Windows toolbar, click the Start button, and select Run.
2.In the field provided, type ping followed by the IP address of the router, as in this example: ping 192.168.0.1
3.Click OK.
You should see a message like this one:
