IBM Atheros A/B/G not fully supported

[Ben Plaut]

The common wireless card- IBM Atheros A/B/G II, does not have full support.
Network configuration can only be done via the Gnome network applet, and
scanning does not work. Scanning should be supported on this card, as LiveCD
distrobutions have detected and scanned with it succesfully.

but does it occur when you are not connected to the network? If you are
connected, then it will scan and find the network you are connected to

[Daniel Stone (daniels)]

It occurs when I'm not associated with the network, and will scan and show every
network in range.

Bear in mind that you need to have the interface up to perform scanning, as with
many other chipsets (having the interface down disabling the thing completely by
delivering it no power whatsoever).
