Laptop as server

I just purchased a Dell 1750 with Win 7 Home, but I installed SBS 2008 to be used as a small office server and demo machine. I seem to have everything working except for one thing and that is the WiFi. I have the Dell 1397 Mini card and the Win 7 drivers are not cutting it.

Does anybody know how to get a driver to get the Wifi 1397 working on Server 2008 on the Inspiron 1750?

Thanks,
