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.
■
Ensure that your computer is configured correctly. Make sure that the
computer can communicate with other devices on the network.
Ensure that the NIC is configured for autonegotiation.
■
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 Use Proxy Server option is unchecked.
