Try installing linux-firmware-nonfree package, and then reboot.

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 ..?

Click on the icon on the top right, and select System Settings. In the
hardware tab, select Bluetooth. Is it on?

Also did you do a clean install or an upgrade to Ubuntu 11.10?
