This is a weird issue and I don't know if anyone else has encountered this. I currently have a wired connection for my xbox and every time it's connected my xbox runs slow. It takes more than a few minutes to just log into the dashboard and anytime I try to load an app, netflix, youtube, etc, it takes just as long. When I unplug the ethernet cable it runs perfectly but I can't connect to xbox live for obvious reasons. Has anyone else had this issue or heard of this issue? Do you think it needs to be repaired or would changing the ethernet cord work? I've already tried resetting the router, turning the console off, everything I can think of and it's still not working. If it needs to be repaired I'm just going to try and get a new one.
