Hi Guys im new to the forum and to backtrack and im having an issue with the wireless card in my macbook
im using Oracle virtual machine with backtrack 5 and have the broadcom BCM43xx

iv done alot of google searches and found alot of info on this card with backtrack but nothing seems to be working for it

when i do an airmon-ng start wlan0 1 i get the message

Found 2 processes that could cause trouble.
If Airodump-ng, airplay-ng or airtun-ng stops working after a short period of tim, you may want to kill (some of) them!

PID Name
564 dhclient3
1839 dhclient

Interface Chipset Driver

If i do an aireplay-ng -9 wlan0 i get a message

Interface WLAN0
ioctl (siocgifindex) failed: no such device

I have ran other commands through that i found from google without success.

can anyone help me get backtrack to recognise and use the wireless card?
