I spent the last several days trying to figure this out, only finding results for the MacBook Pro 8,X model series.

Symptoms:

  1. No wireless connectivity
  2. ifconfig shows only eth0 (wired ethernet) interface
wireless broadcom 12.04

    I finally found the solution here, although it too is posted for working for the MacBook Pro 8,2 series.

    sudo add-apt-repository ppa:mpodroid/mactel
sudo apt-get update
sudo apt-get install b43-fwcutter firmware-b43-installer

    Then install the linux-backports-modules-cw-3.2-oneiric-generic or, if you have the pae kernel installed, the linux-backports-modules-cw-3.2-oneiric-generic-pae package.

    Edit the /etc/modprobe.d/blacklist.conf and add the line:

    blacklist ndiswrapper

    Create or edit the file /etc/pm/config.d/modules and make sure the wireless modules (b43 and bcma) are blacklisted:

    SUSPEND_MODULES="b43 bcma"

    Reboot and the wireless should work.
