Wollen

I've had my little compaq for under 6 months now and it worked great at first but recently it simply stopped connecting to the internet, my desktop, psp, and ps3 all connect wirelessly by way of a D-link, they work fine, also switching the "wireless" button in the laptop changes nothing, and when i went to look for the internal NIC it was missing, the link is there but no matter how many times i click it wont bring up any hardware details or anything... please help
