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 R5000 Series Router to the factory default
before reinitiating the configuration process. For further information on resetting your Netopia R5000 Series
Router to factory default, see “Factory defaults” on page 14-7.

■Verify the accuracy of the default gateway’s IP address (entered in the IP Setup or Easy Setup screen).
■Use the Netopia R5000 Series Router’s Ping utility, in the Utilities & Diagnostics screen, and try to Ping
local and remote hosts. See “Ping” on page 14-2 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 server’s IP address is correct and that it is reachable
from the Netopia R5000 Series 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.
