Comment 2 for bug 644452

Your ath9k driver looks like its functioning normally. What I did notice is that your rfkill state is wireless blocked. There were some changes from Lucid to Maverick in the HP platform driver which is where rfkill state is maintained. You might be able to re-enable wireless functionality from the command line using:

sudo rfkill unblock all

Alternatively, there is likely a key or switch on your laptop that controls rfkill state.
