I need wireless driver help please :P

Hey, I was just wondering if anyone had a download link for a wireless driver card
for Fujitsu Siemens Amillo laptop.
Recently my laptop crashed and had to be Restored to factory settings (i'm pretty sure that's the correct term anyway..)
when I started using the laptop again I noticed that the sound wasn't working, so I Had to get a new sound driver. Since I realised that the wireless wasn't working any more I thought I would try the same route with it.
The problem isn't that it won't connect, it's that the icon for wireless connection has completely disappeared from my task bar, and when I go into my network connections wireless connection isn't an option, which is odd as it used to be before it crashed. Sorry to ramble,
Any help would Be greatly Appreciated.
I am using windows XP.
