Pace (Set-top Boxes): Pace 5268ac-AT&T-1Gbe internet service & XboxOneS
I have at&t internet service on my Xbox one S

Have had trouble from day one. Nat is open on Pv4 and Pv6 and have tried just Pv4. I have changed from cat5e to cat 6 to cat 7 rj45 cords but, still experiencing the issue. I have rebooted Xbox to factory mode. I am lost! After a do a reset everything
will work great for a couple of hours then go to poop don't get it.

Called Xbox support said it is the iSP that's doing it. I believe it is a firewall issue or Xbox it self or even DNS server

Here is what happens after a reset //

My Xbox will start out with speeds of 400 down and 600 up then while I'm playing games it will start to lag and drop out. I will re-run speed test and it is less than 2-20 Mbps down I have seen 0 with a 200-600 up. I can run a speed test on the same network
cable and it will be 700-800 down and 800-981 up. ---//// what is happening to the bandwidth

I have pulled all of my other devices off this internet to see if that was the issue but, not fixing the issue. AT&T had some out checked services replaced router. Only way to fix issue is to unplug Xbox for the night and replug back in then works for about
2-3 hours then lagging again.

H. E. L. P. !
