Getting compat-wireless on Ubuntu

With Ubuntu you have the option of either installing compat-wireless yourself or of installing the package that provides it built by the Ubuntu kernel team. The Ubuntu package that carries compat-wireless is called linux-backport-modules and it has more backported modules than just your wireless subsystem. Its updated whenever major updates are pushed out into the wireless-testing git tree.

# For Ubuntu 8.10 Intrepid users:
sudo apt-get install linux-backports-modules-intrepid

# For Ubuntu 9.04 Jaunty users:
sudo apt-get install linux-backports-modules-jaunty

# For Ubuntu 9.10 Karmic users:
sudo apt-get install linux-backports-modules-karmic

# For Ubuntu 10.04 Lucid users (one of the following depending on the installed kernel. Most user should choose generic):
sudo apt-get install linux-backports-modules-wireless-lucid-generic
sudo apt-get install linux-backports-modules-wireless-lucid-generic-pae
sudo apt-get install linux-backports-modules-wireless-lucid-preempt
sudo apt-get install linux-backports-modules-wireless-lucid-server

Please note that if you are installing linux-backports-modules-karmic and you later decide to install compat-wireless by building it by yourself you are highly encouraged you first remove linux-backports-modules-karmic first otherwise you can run into module dependency conflicts.
