Dell XPS M1330 wireless networking

I recently swapped in a ssd for this laptop.  I reinstalled windows Vista Home Pre and the drivers using the disks that originally came with the laptop.  Things basically work.  But I no longer seem to have a wireless adapter.  Now, I'm pretty sure that swapping a hd and reinstalling software doesn't make a piece of hardware disappear.  But I am at a loss.  I loaded all the drivers.  When I go to the network and share center, the window says there are not networks available.  When I click on diagnose and repair, it tells me to install the wireless hardware.  So, what am I missing and doing wrong...  could really use any kind of advice!
