Connecting to the
Internet
Ensure that you do not have a Web proxy enabled on your
computer. Go to the Control Panel and click on Internet Options. Select
the Connections tab and click on the LAN Settings button at the
bottom. Make sure that the Proxy Server option is unchecked.
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
program on the accompanying CD-ROM as described in
If you can browse to the Router configuration screens but cannot
access sites on the Internet, check the following:
Confirm that the physical connection between the Router and the
cable/DSL modem is OK, and that the link status LEDs on both Router
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.
