For the past few months, I've had a fairly consistent problem where my XBox will lock up (usually 1 to 3 times a night) after I Host, then complete a 1v1 Ranked Match. The game ends, the loading screen concludes, and I'm back to the menu. Once I arrive back on the menu, however, my entire XBox freezes and ceases to respond. The only solution is to manually shut it off via the power button (it won't bring up the menu at that point).
Since I haven't seen a bunch of threads about this, I'm assuming it isn't super common (in a 2 hour play session, it will happen once or twice). Does anyone have any idea what might be causing this? Internet settings, perhaps? (I have a Verizon router on FIOS).
