The COMPAT-WIRELESS project pre-packages the latest wireless code as loadable kernel drivers on a (near) daily basis. This is a convenient way to download pre-patched and archived source… but in order to get the most recent changes (as they are committed) you have to pull the source directly from the kernel.org GIT tree. GIT is a code versioning system similar to CVS, SVN, Bazaar, etc. Below is a simple example of how to do this and compile / install the code. I’m writing this from an Ubuntu installation, but the same concepts should work on other distros. This isn’t an especially difficult process, but it isn’t necessarily obvious either.

There are a few prerequisites for the below instructions to work correctly:

• Kernel greater than 2.6.21

• Kernel headers (“apt-get install linux-headers-generic” in Ubuntu)

• Build tools (“apt-get install build-essential” in Ubuntu)

1. Make a new directory and clone the source trees:

mkdir wireless-testing
cd wireless-testing
git clone git://git.kernel.org/pub/scm/linux/kernel/git/linville/wireless-testing.git
git clone git://git.kernel.org/pub/scm/linux/kernel/git/mcgrof/compat-wireless-2.6.git

2. Make the packages

cd compat-wireless-2.6
export GIT_TREE=../wireless-testing
scripts/admin-update.sh
make

3. Install

cd compat-wireless-2.6
sudo make install

4. Update and repeat steps 2-3 when you want the latest and greatest

cd wireless-testing
git-pull
cd ../compat-wireless-2.6
git-pull

After step 3 you can try reloading the modules dynamically by running “make unload” and “make load” but this probably won’t work if you’re currently using your wireless drivers. Your best bet is to reboot your machine. You can confirm that you’re running the new(er) drivers by listing your kernel modules and look for the mac80211 module.

lsmod | grep mac80211
modinfo mac80211

If there are problems you can uninstall the drivers by running “make uninstall” from the compat-wireless-2.6 directory. Hope this is helpful!
