I have that same laptop and had the same problem:

  1. Connect to the internet using a modem or cable
  2. Use the command sudo modprobe b43 and see the outcome.

If it doesn't work, open a terminal by opening the Dash and typing terminal and clicking on the terminal icon that appears. Then type:

sudo apt-get remove --purge bcmwl-kernel-source
sudo apt-get install firmware-b43-installer

Restart computer.(The change only take place when you restart.) Thanks to our friend Karl for this.
