This error only happens to me on wireless 2.4ghz , and it occurs when the microwave gets turned on. It causes the router to have signal collisions. More than likely you have other devices running on that frequency that is causing the issue. This isn't a bungie issue, it's an internet connection issue. Switch to a higher frequency so other devices don't interfere with the signal. Needless to say but even if you're wired and the main box has wireless capability, and using the 2.4ghz channel, you will get interference.
