Couldn't you use a Live CD like Puppy to download the Windows Wi-Fi files? I
use Puppy Linux when fresh Windows installs have no drivers for LAN or Wi-Fi.
In fact, I just fixed a DSL modem that wouldn't connect until I connected with
my Puppy CD to download the malware scanners and Ccleaner that she needed.
There are Internet Cafes that run on Puppy, too. The new version can use some
Ubuntu 10.04 files, but older computers can use Wary as it's Puppy from Barry.
