Comment 65 for bug 971809

Guillaume: Official/easy enough way to get the kernel modules on top of your existing (eg. Ubuntu provided) kernel. First, I noticed the patches talked about were already in the 'linux-next' at http://git.kernel.org/cgit/linux/kernel/git/next/linux-next.git/log/drivers/net/wireless/ath/ath9k?id=HEAD - added around two weeks ago.

Secondly the Driver Backports (formerly compat-wireless) project has been providing development drivers from linux-next for users of older kernels, so it's possible to do just what I did: get the tarball, compile and install a specific driver and reboot. You keep on using the default Ubuntu kernel but get up-to-date drivers. If you update the kernel from eg. distro archives, you need to recompile the updated drivers.

See https://backports.wiki.kernel.org/index.php/Main_Page for more info, although I find it a bit non-structured compared to the old 'compat-wireless' site that used to reside under http://wireless.kernel.org/.
