I am relatively new to Linux and have been trying to use Backtrack 5 (until few days ago I used Ubuntu 12.10). BT5 doesn't detect my wireless card so I cant connect to any wireless networks, I am using a Broadcom Corporation BCM4313 802.11b/g/n Wireless LAN Controller (rev 01) wireless card. And I am using a netbbok Acer AspireOne. I was wondering is there anything I can do like download drivers/patches etc. to make my internal wireless card work, or will I have to buy an external USB wifi adapter. Also I am booting via USB.

Thank you very much for your collaboration.
