Xbox disconnects when I start an online game the first time

Some times both consoles are turned on at the same time but it happens when only one is on as well

Yes both share same network

All 4 controllers are normal xbox one controllers

They disconnect when playing online and offline games

No pc games

First started happening maybe In September

Also I have a Xbox series X In a Third room that has no issues

It actually started loading faster when he disconnected from the network. From now on he will not be connected when installing games for the first time.

Hello, after the download of the collection 4, the game would not start more!! I asked around and a friend told me he has the same problem (before the "first screen" the screen stays black!!!), I've tried to remove and reinstall all the collection 4 but
no way.. Fortunately, my friend suggested a procedure to start the game: start the game, when the screen "stays balck" press the central button of the on the controller, press the blue key and disconnect from xbox live, the game start with errors, go on selecting
on-line gaming from menu (don't connect on xbox-live), at the last menu go on and connect to xboxlive, now the game is another time stuck, disconnected again (the last time), now the game is released and now you can start with the online game and all maps!
I searched the internet and found other people with this problem but nobody has a solution for the time being, not even InfintyWard or Activision!!

hi, yes i am in the same account and the xbox is online

there is a sync when start the game first time after the reload but it is "empty"

i tried the game on my son account and that is perfect

I was using the first xbox I had at that time. I've had three Xboxes, the first one being the one I purchased the games on. After my internet got disconnected, my games stopped working on the first Xbox, even when I got my internet turned back on. When I
got my second Xbox, I did not have internet at any point in time and did not transfer my licenses. Now I have the Xbox 360 S, and have transfered my licenses to it, and none of the games work online or offline.
