my brother brought his xbox over and it cannot detect the ethernet cord at all. He was on live just last week so I know his xbox port should be fine. The ethernet cord works as it shows up when I connect it to my laptop. The router is compatible with xbox's since I use to use mine on their until it broke. So what could be the problem? Its possible that the router got reset and is blocking the xbox somehow, but my dad is not here to deal with that since he has the router password. Any other ideas?
