Basic Connection Checks

Check that the Router is connected to your computers and to
the Cable/DSL modem, and that all the equipment is powered
on. Check that the LAN and Cable/DSL port link status LEDs
on the Router are illuminated, and that any corresponding
LEDs on the Cable/DSL modem and the NIC are also
illuminated.
Ensure that the computers have completed their start-up
procedure and are ready for use. Some network interfaces
may not be correctly initialized until the start-up procedure
has completed.
Ensure that the Router has completed its power on self test.
Refer to "Alert LED"
If the link status LED does not illuminate for a port that is
connected, check that you do not have a faulty cable. Try a
different cable.

Browsing to the Router Configuration Screens

If you have connected your Router and computers together but
cannot browse to the Router configuration screens, check the
following:
Confirm that the physical connection between your computer
and the Router is OK, and that the link status LEDs on the
Router and NIC are illuminated and indicating the same speed
(10Mbps or 100Mbps). Some NICs do not have status LEDs,
in which case a diagnostic program may be available that can
give you this information. Refer to the documentation
supplied with your NIC for details.
on page 77 for details.
Ensure that you have configured your computer as described
in "Setting Up Your Computers"
computer while it is connected to the Router to ensure that
your computer receives an IP address.
When entering the address of the Router into your web
browser, ensure that you include the full URL including the
http:// prefix. (e.g. http://192.168.1.1)
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 NT/2000/XP, 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 "Using Discovery"
