Thanks Elijah for your response.
I was referring to the window which pops up when we press F2 key and shows radio button for enabling wireless network.
I even tried in Network & Sharing where there is an icon for wireless.
The issue I'm facing, it is always DISABLED and whenever I try to ENABLE first it shows enabling and then enabled but it won't enable the wireless network.
So request you to help in enabling wireless network.
