5 TROUBLESHOOTING Basic Connection Checks ■ Check that the Access Point is connected to your switch or hub and that all the equipment is powered on. Check that the LAN port link status LED on the Access Point are illuminated, and that any corresponding LEDs 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 the LAN port, check that you do not have a faulty cable. Try a different cable. Check also that the Uplink/Normal switch is in the correct position. Browsing to the Access Point Configuration Screens If you have connected your Access Point, admin computer and switch together but cannot browse to the Access Point configuration screens, check the following: ■ Confirm that the physical connection between your computer and the Access Point is OK, and that the link status LEDs on the Access Point 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. ■ When entering the address of the Access Point 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 Access Point, re-run the DISCOVERY software described in Appendix A to discover the Access Point and the IP address it has been allocated from the DHCP server. If there is no DHCP server on your network, the DISCOVERY software changes the IP address of the Access Point so that it is in the same subnet as your admin computer.

■
Check that the Access Point is connected to your switch or hub and
that all the equipment is powered on. Check that the LAN port link
status LED on the Access Point are illuminated, and that any
corresponding LEDs 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 the LAN port, check that
you do not have a faulty cable. Try a different cable. Check also that
the Uplink/Normal switch is in the correct position.
Browsing to the
Access Point
Configuration
Screens
If you have connected your Access Point, admin computer and switch
together but cannot browse to the Access Point configuration screens,
check the following:
■
Confirm that the physical connection between your computer and the
Access Point is OK, and that the link status LEDs on the Access Point
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.
■
When entering the address of the Access Point into your web browser,
ensure that you use the full URL including the http:// prefix (e.g.
).
■
If you cannot browse to the Access Point, re-run the DISCOVERY
software described in
Appendix A
to discover the Access Point and the
IP address it has been allocated from the DHCP server. If there is no
DHCP server on your network, the DISCOVERY software changes the
IP address of the Access Point so that it is in the same subnet as your
admin computer.
