Basic Connection

Check that the Gateway is connected to your computers and to the

Checks

cable/DSL modem, and that all the equipment is powered on. Check

 

that the LAN and WAN port link status LEDs on the Gateway are

 

illuminated, and that any corresponding LEDs on the cable/DSL

 

modem and the NIC (Wireless Gateway only) 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

 

initialised 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 Gateway Configuration Screens

If you have connected your Gateway and computers together but cannot browse to the Gateway configuration screens, check the following:

Confirm that the physical connection between your computer and the Gateway is OK, and that the link status LEDs on the Gateway 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.

Ensure that you have configured your computer as described in Chapter 3, Setting Up Your Computers. Restart your computer while it is connected to the Gateway to ensure that your computer receives an IP address.

When entering the address of the Gateway into your web browser, ensure that you use the full URL including the http:// prefix (e.g. http://192.168.1.1).

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,
