If you are still unable to solve the problem by checking the LED activity, the error may
be caused from configuration mismatch, which prevents the Access Point from
establishing a wireless connection with the network. You may check the following to
ensure normal operation of the Access Point.
WEP keys: If data encryption is activated, always remember to set WEP keys exactly
the same on the Access Point as are on the wireless stations.
Access Control: Make sure that the MAC address of your Access Point is not included
in the Access Control table of other wireless devices.

An Ad-Hoc wireless LAN is a group of computers, each equipped with one wireless
adapter, connected as an independent wireless LAN. Computers in a specific Ad-Hoc
wireless LAN must be configured at the same radio channel.
