Lost A Room On the Sonos App

Hi, I went on my phone and went on to the Sonos App , i went down to click T Bedroom and it wasn't there. It completely has disappeared and I can't listen to my music through Sonos. It has always worked as I always listen to music in my room. Do you know how I add my room back in? What is the problem?

Lately, we have noticed this topic getting a lot of traffic. Although diagnostics are much appreciated, we do not always get the opportunity to conduct one-on-one troubleshooting.

If you are still having issues maintaining connection to one or more Sonos devices, sometimes, it's as simple as turning the router off for a few seconds. If this doesn't help, below you will find some useful content that we strongly recommend reviewing.

This article, that talks about Speakers disappearing or dropping off controller. This is an issue commonly caused by WiFi interference.

If you are still having issues, you may wish to get in touch with our support team via telephone.

Same problem. Was working fine yesterday, but now it won't connect. It's one of four (Office; other three are Master Bedroom, Dining Room and Living Room) and perhaps ironically, the only one in the same room as the router. Diagnostic confirmation 6103663

Your Sonos units are losing connection with your wireless network, causing them to drop from your system. We'd like to get you in contact with our phone team to troubleshoot this issue.

Hi IngeSonos,

There's quite a bit of wireless interference showing up which is likely the reason your Sonos unit is dropping connection with the rest of your system. Please start by changing the wireless channel your Sonos system is using, here's how.

Also, it looks like your Sonos system is not up to date. Please run updates on your system, here's how.

If those steps don't help, please send in a new diagnostic report and reply with the confirmation number.

Hi IngeSonos,

The interference numbers look a bit better. Please try rebooting the missing Sonos unit. To reboot your Sonos speaker, just remove it from power for ten seconds then plug it back in. Once the light on the unit goes solid, see if it shows up on your Sonos app.

If the unit does not show up, or if the light on the unit does not go solid, try adding it back to your system, here's how.
