Check that the terminal emulation software is accessing the correct por t on the computer that’s being 
used as a console.
Tr y pressing Ctrl-L or Return or the ▲ up or down▼ key several times to refresh the terminal screen.
Check that flow control on serial connections is turned off.

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
Tr y changing the Netopia R310’s default speed of 9600 bps and setting your terminal emulation software 
to match the new speed.
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 R310’s ping utility, in the Statistics, Tests, Utilities screen, and tr y to ping local and 
remote hosts. See 
 for 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 ser ver’s IP address is correct and that it is reachable 
from the Netopia R310 (use ping).
If you are using filters, check that your filter sets are not blocking the type of connections you are tr ying to 
make.
Local routing problems
Obser ve 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 ser ving.
