ROUBLESHOOTING
Check that the Gateway is connected to your computers and to the cable/DSL
I
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 are also illuminated.
Ensure that the computers have completed their start-up procedure and are
I
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
I
that you do not have a faulty cable. Try a different cable.
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
I
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,
I
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
I
you include the full URL including the http:// prefix (eg. http://192.168.1.1).
If you cannot browse to the Gateway, use the winipcfg utility in Windows
I
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
I
the accompanying CD-ROM as described in Appendix A.
