I reformatted my hard drive and now my built-in wireless is gone!

I have a Dell XPS laptop that has built-in wireless.

I reformatted it with Windows XP HE after I couldn't even start my computer up at all.

I was thinking once I got my internet up again I'd be able to figure everything else out, but it's not letting me set up a wireless connection and not recognizing that I have wireless at all.

Is there a simple easy fix to this that I'm completely overlooking?

Before anyone says, my wireless switch is to press Fn+F2 and it's not doing anything.

Re-install your drivers from the Dell Driver CD...
MBoard chipset drivers first...then any additional ones...
