War zone Disconnected Everytime!!!

So I have TW and am enrolled in the preview program. Everytime I try to play a war zone match the game quits and I’m kicked back to the home screen. This problem got worse till I got kicked in arena and even campaign. So one solution I tried is to hard reset my router. Which alleviated the problem for a little bit. I could join any game without a hiccup, but it has since returned and I cannot enter war zone matches again. I can play arena however. So… I am searching for the real solution to this problem. Very frustrating. It is likely the preview program is to blame. Any help would be appreciated.
