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.
