First, install the prerequisites by opening a terminal and pasting, one line at a time:

sudo apt-get install linux-headers$(uname -r | grep -Po "\-[a-z].*")
sudo apt-get install build-essential dkms

Please download the appropriate DEB file from Dropbox here:



Open a terminal, and install it with sudo dpkg -i.

Hopefully it works!

Edit: 12.04 now has an updated bcmwl-kernel-source package that reportedly supports BCM43142.
