A-206 User’s Reference GuideConsole connection problemsCan’t see the configuration screens (nothing appears) Make sure the cable connection from the Netopia 4553’s console port to the computer being used as aconsole is securely connected. Make sure the terminal emulation software is accessing the correct port on the computer that’s beingused as a console. Try pressing Ctrl-L or Return or the up or down arrow 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 4553’s default speed of 9600 bps and setting your terminal emulation softwareto match the new speed.Network problemsProblems 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 4553’s Ping utility, in the Utilities & Diagnostics screen, and try to Ping local and remotehosts. See “Ping” on page 13-194 for instructions on how to use the Ping utility. If you can successfullyPing 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 Netopia4553 (use Ping). If you are using filters, check that your filter sets are not blocking the type of connections you are trying tomake.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 flowand address serving. See “Statistics & Logs” on page 12-182 for more information.
