I have switched from BT3 to BT4 on my Macbook Pro 2.1.
My wifi card is Atheros and is detected and working out of the box. In Bakctrack 3 when I used airmon-ng and airodump-ng the signal power was shown in positive dBs but now it's all negative.
It can still inject packets and sniff around but is this normal or should I update the drivers or smt?
Thanks
