If you are using the BT supplied HomeHub 5 VSDL WiFi Router then I suggest changing a couple of settings to get the most of it.
First in your Browser (I normally use Google Chrome, but seem to work with Edge and FireFox) go to:-
And you should see, click on Advanced Settings:-
And you see:-
Scroll to the bottom and enter your password (see card on the back of the HomeHub for this and click OK:-
And you will see the screen, click "continue to Advanced Settings":-
Then click "Wireless":-
Then click "5 Ghz Wireless":-
Then change "Sync with 2.4Ghz" to No and click Apply:-
Also in Advanced Settings I turn off:-
"Home Network" -> "Smart Setup" -> "Enable Smart Setup:" - No - Click Apply.

If you want to Stream or Play your Xbox One game on Windows 10 Device then click the Game Streaming (here my Xbox one is called "XBOXONE" but yours might be called something else.

Or if you actually want to play the Xbox One game on your Windows 10 Device then either buy the Xbox One Wireless adapter (for Windows 10) or just plug the Usb cable in your Xbox One Controller and the other side in your Usb on the Laptop (Windows 10 Device).
