BCM4321 works with the wl driver (as per the boradcom wiki).

First of all have you fully updated your system?
If not, plug an ethernet cable and give the following commands in terminal

sudo apt-get update
sudo apt-get dist-upgade

After the updates are finished and you restart your system, your wireless may already by working.

If not, plug an ethernet cable to get internet, open terminal and give the following 2 commands:

sudo apt-get install bcmwl-kernel-source
sudo modprobe wl

Does your wifi now spring to life? (Did the blue light come up?) Wait 1 minute and then check from your network manager to see if you get the available networks.
