drivers - Can't get wireless on macbook pro 8,2

I'm a linux Newb, and I have tried several of the fixes listed to try and get my wifi drivers to work, but to no avail. Does anyone here know why this isn't working for me, or better yet, how to fix it?

Under lspci -vvv I get the following output:

03:00.0 Network controller: Broadcom Corporation BCM4331 802.11a/b/g/n (rev 02)
    Subsystem: Apple Inc. AirPort Extreme
    Control: I/O- Mem+ BusMaster+ SpecCycle- MemWINV- VGASnoop- ParErr- Stepping- SERR- FastB2B- DisINTx-
    Status: Cap+ 66MHz- UDF- FastB2B- ParErr- DEVSEL=fast >TAbort- SERR-
    Kernel modules: bcma

With sudo lshw -class network I get this output:

  *-network UNCLAIMED

Any help would be greatly appreciated!
