Hi JB,

Thanks for keeping us updated regarding this situation. It is very odd but we are here to help! Try to use a wired
network if possible. You’ll always get the highest-quality video, lowest-latency gameplay, and least interference when
streaming over
a wired Ethernet network. If possible, connect both your Windows 10 PC and your Xbox One console to your home network with Ethernet cables.

Side Note:
If you can’t create a wired connection because of the distance between your console and your home networking device, the following two options might help. Consider investing
in one of these to help you take advantage of the existing wiring in your home:

Powerline network adapters.
These adapters enable you to use the existing electrical wiring of your home as a high-speed wired network.


Multimedia over Coax (MoCA).
These adapters enable you to use the existing coaxial cable wiring of your home as a high-speed wired network.
