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.
