Comment 15 for bug 1160188

I tried upgrading kernel to 3.9, but the poor connection signal persisted. Then I installed compat-drivers from:

http://drvbp1.linux-foundation.org/~mcgrof/rel-html/compat-drivers/

now the connection signal is better than before. Not as good as with windows, but I get to connect in places where I couldn't before.

To try this you need to:
- download the drivers that match your kernel version. In my case, I downloaded compat-drivers-v3.9-rc4-2 because I'm on 3.9 kernel (you can check your kernel v. with uname -r)
- extact tar file.
- cd Downloads/compat-drivers-3.9-rc4-2-su
- sudo make
- sudo make install
- sudo modprobe -r ath9k
- sudo modprobe ath9k
