6 TROUBLESHOOTING

Basic Connection	■ Check that the Router is connected to your computers and to the
Checks	telephone line, and that all the equipment is powered on. Check that
	the LAN Status and SYNC LEDs on the Router are illuminated, and that
	any corresponding LEDs on 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.
	■ 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 LAN Status LEDs on the Router and network adapter 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.

■Ensure that you have configured your computer as described in Chapter 3. Restart your 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 use the full URL including the http:// prefix (e.g. http://192.168.1.1).

■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.
