Network card issue

Hi

Well basically i have a macbook pro 2010 model 2.66 ghz i7 core 4gb ram and have installed vista with bootcamp. I have then spent a good 3 hours messing about with drives from the internet trying to get my wireless to work. it just wont even search for wireless connections.

In device manager it dosent even list an network adapter. I also use 32 bit vista w/e that means.
and no i dont have my installtion cds that came with it but im pretty sure the internet will provide.

I really need some help with this!!!!

Thanks
