How do I disable connection of other devices on Xbox One?

Is this on a mobile device or laptop?

Do you have trouble connecting to any other device on the network?

If mobile you need to make sure Wi-Fi is turned on and its connected to the same router as the Xbox, you are using SmartGlass for Xbox one and you are using the same profile details.

I did do a quick search for your router and if I looked at the right one there are a lot of settings for the firewall one of which disables peer to peer connections. I am assuming that’s how the app connects to the Xbox but I might be wrong but if it is
disabled try to enable it and see if that works.

The NAT is what I'm thinking it might be, but I only have two options for it: Enabled or Disabled. I hate to disable it and then have issues with connecting other devices through my network. I'm not exactly sure how it all works, do you know if disabling
NAT will cause other problems? Also, the xbox.com/nat-help page states that " •You should not experience a NAT warning if you are using a wired modem connection." Do you think that only applies to an Xbox connecting directly to a modem rather than through
a router? Thanks.

To stop your Xbox One from connecting to other devices, you will need to change the settings on your router. To do this, you will need to open your router’s configuration page and look for a setting called “UPnP.”

If you want your Xbox One to connect to a specific device, such as a gaming console or a printer, you can do so by manually connecting it to that device. To do this, you will need to open your router’s configuration page and look for a setting called “UPnP.”

UPnP stands for Universal Plug and Play, and it is a feature that allows devices on your network to automatically connect to each other. If this setting is enabled, it means that your Xbox One will be able to connect to any other UPnP-compatible devices on your network, including printers and other gaming consoles.

How do I disable HBO Go from my Xbox One if the App doesnt connect to HBO GO?

One option online seems to be to disable the uPnP option on my router. I'm not exactly in the know with these things although I do know how to disable it but what effects would it have on my wireless connection, the PC and Xbox connecting as well as Wifi?
