How to let Airport running wifi access under XP?

I run an OEM version of Windows XP Pro with the last version of Parallels. It works better than on my Toshiba.
I can access to the WEB via ethernet (a wire pluged on an ADSL box).

This box is also wifi, I can access to the WEB via Airport with Mac OS X.

BUT! When I'm in WindowsXP, it dont work (Airport is well active in the OS and shown "en1"): Why? Is there a driver, or some thing else, missing? (on my Toshiba, it is so simple!)

 

Are you using "Shared Networking?" That would be the most straightforward way to do this.
