ASUS ZenWiFi Pro ET12 wireless dropping out when Xbox Series X is on

[etgadsby]

Hi, here's an odd one. I have a 2 node ASUS ZenWiFi Pro ET12 system and a Xbox Series X (hard wired). The main node and the Xbox are in the same room fairly close together. When the Xbox is on we see serious wireless performance issues. The Xbox is connected to the wired networking and from what I read means that the it's Wifi has turned off. My only conclusion that the xbox controller wireless is overpowering the signal.

We've had this problem a while but usually there isn't somebody using the xbox at the same time as my wife teleworks. I live in the MidAtlantic and the storm has us all snowed in and now it's becoming a problem again as the kid want to use the Xbox during the day.

Has anybody had this problem and or has ideas on how to remedy it? Thanks!

A bit about my network topography. I have FIOS connected to a mini PC running Pfsense that's my DHCP server/gateway. This is connected to a gigabit switch. The ASUS ZenWiFi Pro ET12's first node is connected to the "core" switch. It is set to AP mode. The second node connects to the first with Cat6 via a direct connection (doesn't touch the core). The Xbox is also connected to the core. The core and gateway are in the basement. The Xbox and first node are in my TV room on the first floor. The second node is on the opposite side of the house.


Thanks for any and all help!

what frequency is the Xbox wireless controller using ?
Can you turn off your 2.4 GHz radios on the ETs and use 5 GHz only ?
Should be plenty of bandwidth on 5 GHz alone for any user. i've been running on 5 GHz on AC class APs with 5 users, including 2 work at home. You might have to add an AP to get the coverage you need.

A little research suggests that it's using the same bandwidth as BlueTooth. Of course that M$'s proprietary system so... I have to guess a little.
