Ok so I'm using backtrack R1 (disk) on my old black Macbook and I noticed I couldn't connect to aireplay-ng

Under chipset it says "Atheros AR5481"
Under driver it says "ath9k - [phy0]"

I'm not to knowledgeable in this but isnt ath9k for chipsets that are ar9xxx not ar5xxx its ath5 for that?

If it is then please tell me how I could switch it out for the correct driver and if not WHAT IS THE PROBLEM!

anyway thanks in advance!
