A-2 User’s Reference 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 Netopia R9100 to the factory default before reinitiating the configuration process. For further information on resetting your Netopia R9100 to factory default, see “Factory defaults” on page 14-6.

Console connection problems

Can’t see the configuration screens (nothing appears)

■Make sure the cable connection from the Netopia R9100’s console port to the computer being used as a console is securely connected.

■Make sure the terminal emulation software is accessing the correct port on the computer that’s being used as a console.

■Try pressing Ctrl-L or Return or the ▲ up or down▼ key several times to refresh the terminal screen.

■Make sure that flow control on serial connections is turned off.

Junk characters appear on the screen

■Check that the terminal emulation software is configured correctly.

■Check the baud rate. The default values are 9600, N, 8, and 1.

Characters are missing from some of the configuration screens

■Try changing the Netopia R9100’s default speed of 9600 bps and setting your terminal emulation software to match the new speed.

Network problems

This section contains tips for troubleshooting 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 R9100’s Ping utility, in the Utilities & Diagnostics screen, and try to ping local and remote hosts. See “Ping” on page 14-2for 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 R9100 (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 12-3for more information.
