Possible Solution
Ad hoc connection: verify that the network names (SSID's) and network keys (WEP) of all
computers to be connected have been configured correctly. SSID's and WEP key values must
be identical on each machine.
Access Point (Infrastructure) connection: set the network name (SSID) and network key to
the same values as those of the access point.
Set the Network Authentication value identically to that of the Access Point. Please consult
your network administrator for this value, if necessary.
Ad hoc connection: Retry connection after shortening the distance to the destination
computer or removing any obstacles for better reception.
Access Point (Infrastructure) connection: Retry connection after shortening the distance to
the access point or removing any obstacles for better transmission.
Check if the wireless switch is turned On. Go to Start -> Control Panel, and double-click on
Network and Sharing Center. Click on Diagnose and repair, then click on Enable the
network adapter.
Check if the computer to be connected is turned ON.
The use of identical or overlapping RF channels can cause interference with the operation of
the WLAN device. Change the channel of your Access Point to a channel that does not
overlap with the interfering device.
