Another two questions:
Do you know for a fact that you have got a wireless card?
If so, and it is internal, is it turned on? There is often a small hardware
switch on laptops taht can be turned on or off, or a combination of keys,
usually one or more function keys, that has to be pressed to turn wireless
on. If it is turned off, it won't work.
