    Question Macbook Pro 8,1 Broadcom Wireless Card (BCM4331) Not Recognized

    I recently installed BackTrack 5 R1 on my late 2011 13" Macbook Pro 8,1 and everything installed fine after some helpful Google searches.

    One of the main issues I am having is that the Wireless card on my Macbook isn't being recognized. When I use Wicd Network Manager it doesn't see any wireless networks (No Wireless Networks Found). Also, when I do a iwconfig it says "no wireless extensions". I'm kind of stuck at the moment it would greatly appreciate any help anyone can provide.

    The wireless card information after doing a lspci is as follows:
    Broadcom Corporation BCM4331 802.11a/b/g/n (rev 02)

    Please let me know if anyone has gotten the wireless card functioning correctly on a Macbook Pro 8,1?

    Looking forward to your replies.

    Can you write outputs of
    ifconfig
    iwconfigls
    ls /lib/modules/`uname -r`/build
    ls /lib/modules/`uname -r`/kernel/net/wireless
    uname -r
    i had allot of problems with broadcom but now i have a connection and its working fine >)

    For those that are having problems with the BCM4331 wifi card this is how I fixed it:
    First: Enable the b43 drivers.
    http://www.backtrack-linux.org/wiki/..._Backtrack5_r2
    Second: Then you should be able to follow the guide here to install the drivers.

    What if the second step doesn't work?
