I have recently installed ubuntu 12.04 LTS in my laptop. Everything looks cool, i am pretty much happy with it. But i have a minor regarding wifi and wired connection.

Ubuntu is unable to find the wireless or wired connections which are available. I have searched and found to try with the below command,

rfkill list all
Output of this command doesn't give me any detail about wifi, it states about the bluetooth device only. Can anyone please help me here?
