I understand many have had this issue in America with a certain internet provided but im in Australia and currently experiencing the same issue. I ran speed tests and got 19mbps download and 1.1mbps upload from my router. NAT is open. My setup is modem to Wifi extender to Xbox.
First night playing it happened every game without fail about 3/4 of the way through a warzone match i would drop out. I then went and updated my routers firmware and it seemed to improve things for that day on the 6th of november i didn’t drop out once. Now it’s back to normal i never finish a warzone match. I don’t experience lag spikes or problems I’m just booted and says connection lost. None of my friends have really had this issue and in no other game i’ve played on this console has this problem occurred with staying connected to online multiplayer. Ive looked into all avenues and im putting the blame all on 343 shoulders here. Having multiple times throughout owning consoles adjusted NAT settings and port forwarding situations to fix problems i can safely say this isn’t a problem on my end and this needs to be fixed ASAP
It’s getting beyond frustrating and it doesn’t seem 343 is really tackling what is a major issue for a game. Is anyone else in Australia having this problem? I have telstra cable if that helps as well.
