Please see the following link. You need to download broadcom drivers. Wireless doesn't work on a Broadcom BCM4312 –  Web-E Jul 25 '12 at 17:34

what is o/p of cat /etc/modprobe.d/* | egrep 'bcm' –  Web-E Jul 25 '12 at 18:19
    
i have absolutely no idea, i am clueless about things like that, i have copied commands that seemed to be usefull in similar problems (posts) because i thought it might help people who know this stuff know what is going on –  olivier Jul 25 '12 at 20:09
