My Arc/Sub 1/rear Ones system used to work fine but now I can’t connect the rears. I’ve reset Ones and tried the suggestions in related posts. I was able to get the rears going without the rest of the system, but when I remove then Set Up Surrounds they won't play. Once they played for a second and then quit. They automatically assume the identity of Living Room 2 and Living Room 3, while they should both be subsumed in my Living Room (+Sub, Arc) system.

The Ones, Five (new), and Beam 1 in other rooms work fine. I’ve had Sonos for years and have always been able to trouble shoot problems, but I’m at the end on this one.

Try unplugging the Arc and Ones from power for a couple of minutes and reboot your router and phone. Plug the Arc and Ones back in and make sure WiFi is enabled on all three speakers in the Sonos app. Wait until they are all connected to your network and then try to add the Ones as surrounds to the Arc again.


Is your Arc wired or wireless?  If wired, don't turn off the Wi-Fi.  It needs Wi-Fi on in order to connect to the surrounds.


Everything is wifi. I’ll try unplugging the Arc and both Ones and restarting the router tonight or tomorrow and I’ll report here. It’s a good idea. Thanks


It worked! Thank you, thank you, GuitarSuperstar! Sending a thought chord your way.
