Totally mind blowing that no one from 343 has commented on this whatsoever since 10/28. I've updating my firmware on my router, removed my router from the equation by singling out my XBone. Port forwarded, changed DNS, QoS. Damn near anything and everything I can do on my side.
343 you need to own this issue. Acknowledge it at least if you have it pinned down yet. A thread saying "hey if you have connection trouble post here" is inadequate at best. Your CS staff will be hearing from me soon in regards to a return if you can't at least get out in front of this, and act like you give 2 shakes.
