Справочное Руководство для Netopia 430 s

If you suspect that power was restored after a power outage, and 
the Netopia ISDN Router is connected to a remote site, you may 
need to switch the Netopia ISDN Router off and then back on again. 
After temporar y power outages, a connection that still seems to be 
up may actually be disconnected. Rebooting the Router should 
reestablish the connection.

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

■

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

■

Use the Netopia ISDN Router’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.farallon.com, for example), verify that the DNS ser ver’s 
IP address is correct and that it is reachable from the Netopia 
ISDN Router (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.

■

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.
