Show output from sudo lspci -v, for 'Network controller'. Should show details of Broadcom device. –  david6 May 26 '12 at 6:09
    
Or, more simply (and 'Broadcom' specific): lspci -vvnn | grep 14e4 –  david6 May 26 '12 at 6:21

Try the instructions at:

You need to confirm the exact version of Broadcom chip, and how to make this work on Ubuntu 12.04 LTS
