Network problems

This section contains tips on ways you can troubleshoot a networking problem.

Problems communicating with remote IP hosts

Verify the accuracy of the default gateway’s IP address (entered in the IP Setup or Easy Setup screen).

Use the Netopia R2121’s ping utility, in the Statistics, Tests, Utilities screen, and try to ping local and remote hosts. See “Ping” on page 15-2for instructions on how to use the ping utility. If you can successfully ping hosts using their IP addresses but not their domain names (198.34.7.1 but not garcia.netopia.com, for example), verify that the DNS server’s IP address is correct and that it is reachable from the Netopia R2121 (use ping).

If you are using filters, check that your filter sets are not blocking the type of connections you are trying to make.

Local routing problems

Observe the Ethernet LEDs to see if data traffic flow appears to be normal.

Check the WAN Statistics and LAN Statistics screens to see more specific information on data traffic flow and address serving.
