Hello 343,
first off I wanted to thank you for one of the greatest video games of all time. I’m currently level 80 and the game has only gotten better with time. However, as of the last week or two, I have been kicked out of multiple warzone games more than halfway into them. Not only did I lose out on any RP earned, but I also lost some legendary and rare RP jackpots. That’s like playing 20 mins of halo and losing out on 6,000 RP with the applied boosts. I understand that glitches happen but you should look into this because I’m missing out on getting some gold packs. Also, I don’t buy gold packs because that takes the fun out of the game. Those of you that do, thanks for funding the chanpionships! 
any other Spartan comrades dealing with this issue?
I had this issue before - try unplugging the router/modem for 60 seconds, turn off things connected to the router/modem that don’t need to be, and after those two make sure you restart your Xbox (not just turn off and on, go to the settings and restart).
If those don’t work you might want to call your ISP or, depending on other circumstances, replace an older router.
After all that there are a few things you can manually do with the Xbox to improve it’s connection: http://www.dualshockers.com/2014/05/14/ps4-and-xbox-one-heres-how-you-can-improve-the-speed-of-your-connection/

I had to do all of these above and now I don’t lag at all anymore.
