Strange loss of connection, Game quits everytime

Okay, since launch I’ve had disconnection issues with halo 5 and only halo 5. My problem seems to be a little different from things I’ve read on the thread. So what happens in my case is that I start a search in arena or Warzone and before the game can load, my game will make a glitchy noise and then turn off. Everytime. It takes me 6 plus times of doing this before I can get into one game. No error message or anything, the game will just turn off! Now what is happening is that not only will the game turn off but my xbox will restart… What is going on? The last and strangest thing is now when the game shuts off and kicks me to my homescreen my modem will reset.!? So I’m at a loss of what the problem is. I have reset my xbox, redownloaded the game many times, reset my router, but the game continues to quit. Any help would be greatly appreciated!

Any ideas from anyone?
