You'll probably have the same wireless issues in 12.04, though. It seems one solution for your card is found here:

First try the fix there to disable hardware encryption. Open terminal window then type:

Code:
sudo modprobe -rfv ath9k
sudo modprobe -v ath9k nohwcrypt=1
If that works, make it permanent this way:

Code:
echo "options ath9k nohwcrypt=1" | sudo tee /etc/modprobe.d/ath9k.conf
Thanks this fixed it for me.

I was able to connect to my router, but was getting around 50% packet loss and very high pings. This fix has stabilized things for me.
