I'm not sure whether the bcm43xx driver supports WPA2-PSK/AES but

a quick google turned up:


Possibly the 2.6.24 kernel is required ( Gutsy does not have that of
course) .

I am currently using the bcm43xx , on my iBook G4 running the PPC version
of Feisty, but only using WPA1 with shared keys, PSK etc.

Perhaps yours is falling back to something possible because it can't
handle the configuration that you prefer?
