Disconnected from internet last few builds

Take out the main power for a few minutes and disconnect your internet. After waiting a few minutes, turn your xbox back on with the internet still disconnected. Everything should be fine from there. You can turn your internet back on in game. Hope this
helped.

If it's the youtube app, how would it cause any and all my games to randomly crash or get disconnected from the internet?

I don't have the insiders build on my xbox

How long does this happen for, when it happens? Is it just a few minutes, or hours? The only reason I can think of that the network speed goes down to 0 would be if it's not connecting any more with the Wifi or internet connection. Does your internet ever
drop or stop for a period of time? A few years ago I used to have a bad internet service that would just drop internet several times a night and it would disconnect me from Xbox Live. It would last anywhere from a few minutes up to 15-20 minutes, then it would
come back up. I wound up switching internet providers and then I had no problems. I would check the internet connection first and go from there. Good luck!

My controller starts acting weird about 15 minutes before the low battery indicator pops. When getting the "disconnects" it usually remembers the last input; been a few times I've fell to my death in Fallout 4 because of "walking" off the top of a building.
Should probably mention the controller doesn't fully disconnect to the point it needs to be powered back on, but more of a "lights flashing, last input, controller disconnected message, press A" type of thing.

Seems to be directly related to the type of battery and power level of said battery.

Peace, J.R.

First disconnect from the internet power off console then power back on after a few minutes, then delete profile and redownload it should be fine after that.
