■
If you cannot browse to the Gateway, use the winipcfg utility in
Windows 95/98/ME to verify that your computer has received the
correct address information from the Gateway. 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 Gateway is
192.168.1.1 (the address of the Gateway). If these are not correct, use
the
Release and Renew functions to obtain a new IP address from the
Gateway. Under Windows 2000, use the ipconfig command-line
utility to perform the same functions.
■
If you still cannot browse to the Gateway, then use the Discovery
program on the accompanying CD-ROM as described in
Appendix A .
Connecting to the
Internet
If you can browse to the Gateway configuration screens but cannot
access sites on the Internet, check the following:
■
Confirm that the physical connection between the Gateway and the
cable/DSL modem is OK, and that the link status LEDs on both
Gateway 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
Gateway 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
Gateway to ensure that the correct MAC address is presented, as
described on
page 60 .
■
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.
On Windows computers, this can be found under
Control Panel >
Internet Options > Connections .
