Need help with ICS and Xbox Live :(

Heya all, it's been a while, but I figured people from here would probably know what they're talking about so there you go.

Right so On my laptop that's running Windows Vista I recently learned that I can access Xbox Live via ICS with a 3G USB modem using my laptop as the router.

So I've been trying to "allow other computers to share this computers internet connection" via the tick box, to no avail. I always seem to be getting errors of one form or another... I can't recall any right now and I don't have my laptop on me now either, so if anyone could help with troubleshooting or anything it'd be great.

 

What errors are you getting?

 

Ok theres a better way that I use:

1. Get an ethernet cord
2. Get a ethernet port and a wireless card (if you dont already have!)
3. Go to "View Networks" (Where it shows the adapters)
4. Select both the Wireless Adapter and the Ethernet Port
5. Hit "Bridge Connections"
6. Plug the Ethernet into the laptop and 360.
7. Voila, Xbox Live!

(Works for me ) (I also have proof it works too.)
