Comment 36 for bug 318942

SW,

I recommend you to stick with the ubuntu kernel. A PPA is always missing packages like backport-modules, ubuntu-modules etc. So you might get problems with update processes. Either stick with one kernel or everytime recompile/install (how i do it). What is the problem with compiling? To decrease compiling time you can compile for specific cards only, i always compile for usb and hda-intel only like this:

./configure --with-cards=hda-intel,usb-audio
make
make install

only do that, no external packages etc. Compiling is the cleanest way to install kernel modules. Your wireless probable didnt work of other kernel. And Im telling you Ubuntu is not gonne fix this until next release in half a year.
