A-2 Firmware User Guide

Note: If you are attempting to modify the IP address or subnet mask from a previous, successful configuration attempt, you will need to clear the IP address or reset your Router to the factory default before reinitiating the configuration process. For further information on resetting your Router to factory default, see “How to Reset the Router to Factory Defaults” on page A-3.

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 Firmware Version 8.4’s Ping utility, in the Utilities & Diagnostics screen, and try to Ping local and remote hosts. See “Ping” on page 10-2for 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 Router (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. See “Statistics & Logs” on page 8-4 for more information.
