How to connect your xbox 360 to the internet using At&t Wifi in a hotel room

Theoretically, you should be able to use your laptop, connect the ATT wifi, go into network adapters, right click the ATT device, then properties. Enable internet connection sharing. Verify you still have a connection, then you should be able to run an ethernet cable from the network jack of your laptop to your xbox. I tried this once on a desktop pc that had no wireless card and it worked. So theoretically it should work for you.
