Random disconnection of wifi

Enable a perimeter network
(also known as DMZ) functionality on a router is used to remove restrictions to the Internet. This essentially moves your device to an area outside your network firewall. If you enable perimeter network
functionality on your router, you should be able to connect to Xbox Live, join games, and host games or parties.

It is critical that you use a static IP address on the console when you set up a perimeter network. To set a static IP address, use your router’s DHCP reservation function, when available. If this is not
available, you will have to set up manual IP settings on your Xbox console. You will only be able to place one Xbox console into the perimeter network. Therefore, if you have multiple consoles, this solution will only resolve the issue for one Xbox console.

I suggest you always use an Ethernet cabled wire connection when you see any difficulty in Connecting to the Internet.

Hi there WarrenD2

Have you tried using a wired connection instead to see if there is a issue on the xbox one wifi card or some other issues that could be causing such as interference or some short range issue ect.

Random game disconnects will only happen over wifi they shouldn't happen while connected via the ethernet.

Are you using a wired connection or WiFi to connect to your router?

If using WiFi and 3rd party headset Disconnect the headsets or look for other

Wireless interference that may be causing these dropouts from XBox Live when you are updating.

A wired connection causing dropouts may be a Faulty cable or port on your router.
