Grrr this question has been asked over and over again, but im obliged to help you since no one is likely to respond to your question and because I had the same problem with my compaq mini. In order to get the wifi card to work you need to upgrade BT system kernel. (http://www.backtrack-linux.org/forum...forum/1161.htm) details on that page on how to do it. But it is not worth doing reasons why, number one, some of backtracks programs will not function properly unless you know how patch a kernel, number two, broadcoms are useless for security penetration, they don't support packet injection and i've been reading that it is a pain in the a** to try and crack WEP with them forget about WPA. Because they can only work monitor mode. My suggestion to you is to get and Alfa usb wireless card like I did they are plug in and play and they are cheap 40 dollors and less.
