Connecting to wireless
I just experienced the same issue - I installed windows xp pro via bootcamp. I couldn't connect to my wireless router (time capsule). I'm using a macbook pro (2007) 3,1 running snow leopard. The first thing I made sure of was that I installed the snow leopard cd into my computer, while in windows xp, in order to install the available drivers from the cd.
Then....
I ultimately connected to my wireless network at home (time capsule) by downloading all the microsoft updates, then downloading the updates for bootcamp, and then by downloading the updates to airport utility. These are the steps that allowed me to connect to my wireless network. I'm not sure how these would apply to you.
Hope this helps in some way.
