Kosher Ubuntu 12.10 - Broken wireless network

After you install Ubuntu 12.10 and update the installed packages to the latest version, your machine will stop to find wireless networks. Unfortunately the latest kernel update for Ubuntu doesn't work well with Broadcom (BCM) wireless network chipsets.

What you need to do is connect your computer to the wired network, download kernel headers...
sudo apt-get install linux-headers-generic

...rebuild and reinstall your wireless network chipset module...
sudo apt-get install --reinstall bcmwl-kernel-source

...and finally reload the mentioned module.
sudo modprobe wl

Now do enjoy your wireless network again.
