wireless

I have recently installed ubuntu 12.04 in sony vaio VPCEH. And updated all the available updates through update manager.

When i switch on the bluetooth/wireless (hardware switch), only the bluetooth is turning on. For wireless, it shows as "hardware disabled".

P.S: It was working fine few days before. Suddenly It is not turning on.

i just get an answer for this question while googling.

just enter the following command in the terminal. "sudo rfkill unblock all"

This will unblock all hardware ports.

that's it!!!!!! :) It works,..
