xBox One connecting to Deco X20 but not actually working
I recently purchased and installed the TP-Link Deco X20 (2022Jan05). So far it's been a great mesh system and easy to install... up until I tried playing my xBox One.
Setup:
I have a Shaw Hitron Wifi Modem. The first TP-Link Deco is connected directly to the Hitron Modem via ethernet, and is only 1 foot away.
I then have the first TP-Link Deco connected via ethernet to a TP-Link router a foot away. The two other Deco units are then connected via ethernet backhaul (cords running through the walls) to the TP-Link router.
My xBox One connects to the the main Deco unit via WiFi fine. But when it comes to actually using the xBox One, it does not actually seem to be connected. XBox says the WiFi connection is at full bar strength, but when I run the 'test network' on xBox, it fails the test. Using the Deco App, the xBox is a connected device but while it is running the test, it is not transferring any data.
I'm not sure what I did wrong as all my other devices (TVs, Phones, Laptops, Cameras, other IoT devices) seem to be working just fine; it is just this xBox. I've restarted both the xBox and Deco systems and still does not work.
