If you cannot browse to the Router, use the winipcfg utility in
Windows XP to verify that your computer has received the correct
address information from the Router. From the
Start menu, choose
Run and then enter
cmd
. Check that the computer has an IP address of
the form 192.168.1.xxx (where xxx is in the range 2-254), the subnet
mask is 255.255.255.0, and the default Router is 192.168.1.1 (the
address of the Router). If these are not correct, use the
Release and
Renew functions to obtain a new IP address from the Router. Under
Windows 2000,XP,and Vista, use the ipconfig/all command-line utility
to perform the same functions.
