If you cannot browse to the Router, use the winipcfg utility in
■
Windows 95/98/ME to verify that your computer has received the
correct address information from the Router. From the Start menu,
choose Run and then enter winipcfg. 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, use the ipconfig command-line utility
to perform the same functions.
If you still cannot browse to the Router, then use the Discovery

and modem are illuminated.
Confirm that the connection between the modem and the cable/DSL
■
interface is OK.
Ensure that you have entered the correct information into the Router
■
configuration screens as required by your Internet Service Provider. Use
the "Internet Settings" screen to verify this.
For DSL users, check that the PPPoE or PPTP user name, password and
■
service name are correct, if these are required. Only enter a PPPoE
service name if your ISP requires one.
For cable users, check whether your ISP requires a fixed MAC
■
(Ethernet) address. If so, use the Clone MAC Address feature in the
Router to ensure that the correct MAC address is presented, as
described on page
For cable users, check whether your ISP requires a fixed Host Name. If
■
so, enter the required Host Name in the Internet Settings screen.
Ensure that your computers are not configured to use a Web proxy.
