Comment 35 for bug 1160188

I've backported the patch from https://bugzilla.kernel.org/show_bug.cgi?id=49201 to precise. It can be applied to the source of 3.5.0-34-generic (cd /usr/src && sudo apt-get source linux-image-3.5.0-34-generic) after entering drivers/net/wireless/ath/ath9k directory.

I recompiled ath9k modules using this guide: http://www.codewhirl.com/2012/04/how-to-compile-a-single-module-in-ubuntu-linux/. Now the signal strength is the same as on other notebooks and it does not disconnect.
