Ubuntu 12.04 LTS - wifi issue

Hi,

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,

Code:

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?

Without knowing anything about your hardware it is impossible to help you.
Please post the output of

Code:
