Long time Sonos user with little issues.
I have an issue which is seeing one room constantly disappearing from the controller, and can only come back via a factory reset and reconnect. I’ve swapped the speakers from other rooms, and the speakers are fine, the issue is no matter which speaker goes in that room, it drops off.
I was running via wifi, then disabled it and put a hard wire into the speaker. Same issue occurs.
Any ideas what could be causing this?
