Yes you can if you have an available ethernet slot on your computer you can plug a cord into that and then to your xbox 360 (you need wireless on your computer to do this unless you have two ethernet slots). Then just got to the start menu, control panel, go to Network Connections, right click your connection that is connected to the internet %26amp; click properties, go to the advanced tab and put a check mark in the box marked "allow other network users to connect through..." and then click ok. You should now have an internet connection being sent through your comp ethernet slot to your xbox.How do you hook up live on an xbox 360 through your computer?
