Okay, so this has been going on for quite some time now, probably 2+ years and we've just put up with it. What happens is me and my brother each have an xbox. And just about 80% of the time, when one of us get's online while the other one is already online, the one who was already on gets kicked off. Resetting the router only works about 50% of the time for some reason. I would think it is an ip conflict, but I have even tried setting our router to a static DNS and giving them separate ip's but still getting kicked off by each other. The cable company here sends out brain dead employees who have no idea what you're talking about when you say something about your xbox or ip address or any of that. Even if no other electronic device (that uses the router) is online in the entire house, our xboxs still conflict. My router is a Linksys WRT54G. Any advice anybody? I'll let you know if i've already tried your suggestion.
