: Can I connect 8 Xbox One devices by cable?

If you mean LAN, yes, if the game supports it

As long as both devices, the xbox One and the device using smartglass, are in the same section of the network, they should be able to connect. No matter if the One is connected by cable and the smartglass device is connected wireless, as it is not a direct
(wireless) connection between both devices, but a connection over the network.

@ Rodrigo he's talking about the powrr brick not the later figure8 consoles

Well no og.xbox one wont fit.in any modern device

You can buy any cheap.figure 8 cable at an electronic store

Xbox one s and above have figure 8 as ms stopped manufacturing the power bricks

Hi Kőcs, my name is Jhon, and will be a pleasure help you

The HDMI IN FROM SAT/CABLE connector on the Xbox One S can be used to connect devices that have an HDMI output. Some devices that can be connected to this connector include:

*Satellite or cable receivers
*Blu-ray or DVD players
*Game consoles
*Computers
*Other devices with HDMI output

Best regards

Hi,

Can you check if your network profiles are correct (or the same) on your windows 10 device ?

Network profiles can be different between multiple network devices.

Wifi is maybe set on private network while the cabled network is set on public (just an example)

Yep, both have the same profiles. Both are connected by cable network on the same profiles.

Update: the same error occurred when I try to connect my iPhone to Xbox with the app. If the xbox one is under wifi network all works, but if the xbox one is under cable network iPhone don't see the xbox one connected.
