Hi, I'm new here, and I apoligize that my first post is a "help me please" deal, but I followed a bunch of links on various other help forums and ended up here. I hope you don't mind. I've got a WRT54G v3. It handles all my wireless and computer traffic fine, but messes up whenever my Xbox uses anything more than a trivial amount of bandwidth. When playing games, it'll disconnect me every half an hour if I'm hosting. It's worse on some games, like Splinter Cell, where I can't even get a game in without getting disconnected. If I stream content, it disconnects me every 5 minutes or so. If I try downloading content, it'll last just a couple of minutes at most. Now, what's weird about this is that it's ONLY the xbox that disconnects, not my PCs or anything. It's also strange that it's not just the connection to live that dies, it's all incoming traffic to the Xbox that gets knocked out. Any content I'm streaming from the PC too, just up and stops. I've tried all sorts of things to fix this, reseting the router, DMZing the xbox, and such things, and nothing fixes it. Any ideas? The connection to the Xbox is wired, not wireless, if that helps any. No, it doesn't help to switch firmware either. I went from stock to DD-WRT and it's still giving me problems, so I dunno what could be the problem here. Is it possible there's an issue with the cable itself? If so, how do I test a cable for possible signal degradation?
