Atheros AR9285 on Ubuntu 11.10 Sony Vaio VPCEH - wifi does't works

[Dixon Xavier]

Installed linux- firmware-nonfree package..
After reboot, no change :(

Currently am unable to check wi-fi connectivity (no wifi connection in my home),
am checking bluetooth connectivity instead...
thinking both are interconnected, ie., functionality by same hardware...

I can't turn my bluetooth on..

How can i fix it ..?
