I actually wonder myself, given that you say you can detect no networks if it is a hardware rather than a software problem, I suspect if it was something like over zealous security measures you'd be able to detect current networks, but not to connect to them.
Some brands of laptop have a wireless switch which you can use to disable all wireless capabilities. It's handy if your going on an aeroplane. I would look around for something like that, perhaps ask someone to check the and back of your laptop, usually they also come with a light which is on when wireless connectivity is possible.

@Ethin, double posting is sometimes unavoidable, especially if a person has a dodgy connection and the page had to load more than once, I've done it myself quite accidently. It's an easy thing to fix (indeed I've just fixed this), so need for throwing around accusations, especially to new members.
With our dreaming and singing, Ceaseless and sorrowless we! The glory about us clinging Of the glorious futures we see,
Our souls with high music ringing; O men! It must ever be
That we dwell in our dreaming and singing, A little apart from ye. (Arthur O'Shaughnessy 1873.)
