My wife and I recently moved to Colombia, South America to teach at an international school. I got on xbox.com and moved my account to Colombia. It allows me to log on, I've even chatted with a friend on there, however, when, for example, I'm trying to play Modern Warfare 1 or 2 multiplayer, I select to find a game, or join a game, and it won't find a match, even though there are hundreds of thousands of players online. Then, it would sort of freeze and my modem/router resets. So, basically every time I try and find a match on multiplayer, the router resets. Any help, please??????
