Unique 360/W7 issue?

Ok, I looked to see what all I had hooked up that might cause a fubar kinda problem, and since I'm at my new house (with cable woot!) the net is a lot faster... Anyways, here is what I'm running

Emachines ET1331G

AMD Athlon II x2 235e Processor 2.70Ghz

6G ram

64bit Os

And I'm routing internet through a Netgear USB device. Netgear WPN111 USB 2.0, and if it's possible at all to use THAT particular USB device to route internet to my Xbox, then that would be great.

I have a Netgear WG311v3 wireless card, but apparently there are no drivers that are compatible with W7, so it's just taking up space in the back of my PC.

That's all I can think of off the top of my head, if anyone has some more input, please feel free to post away and give me some pointers, as my wife uses her laptop at work, and if I have a day off, I'd like to be on Xbox Live. Thanks in advance and I hope this helps!

Oh and when I try to bridge the connections, I get:

To create a network bridge, you must select at least two LAN or high speed internet connections that are not being used by internet connection sharing.

Umm....bump?
