Hello group,
I had just burned a copy of BT2 and I am having problem getting my wg511t set up so I can use kismet or aerodump. I used to do this with BT1:

ifconfig ath0 up
iwconfig ath0 mode monitor
airodump-ng --ivs bssid 00:11:50:3B:FD:89 -w /mnt/sda1_removable/new/captured -c 6 ath0

In BT2 I get the following errors:

bt ~ # ifconfig ath0 up
bt ~ # iwconfig ath0 mode monitor
Error for wireless request "Set Mode" (8B06) :
SET failed on device ath0 ; Invalid argument.
bt ~ # airodump-ng --ivs bssid 00:11:50:3B:FD:89 -w /mnt/sda1_removable/new/captured -c 6 ath0
ioctl(SIOCSIWMODE) failed: Invalid argument
Error setting monitor mode on ath0

Im lost now. Any help will be appreciated!
