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.

Hi Toni,
Please try rebooting your missing player by removing it from power, waiting ten seconds, then plugging it back in. If this does not bring the unit back, there maybe some wireless signal interference preventing connection. To see if this is the case, we'd like to see some data from your system. Please submit a diagnostic and reply with the confirmation number: Submit diagnostic.

Hi Frederic,

Your missing Sonos units are connected and communicating with the rest of your Sonos system. They do not show up because they have no IP addresses. Your router is responsible for assigning IP addresses to components on your network, including the Sonos speakers. Please try rebooting your router. Many times this will cause your router to send out IP addresses to all the components on your network.

If rebooting your router does not work, please let us know. We will get you in contact with our phone support team to help log in to your router to check settings.

Hi Mikefenna,

There looks to be some wireless interference on your system which could explain why one of your units is not showing up. Please check to make sure your BOOST is not too close to your router or any other wireless device. We generally recommend keeping a couple feet of distance between them.

It may also help to change the wireless channel on which your Sonos system operates, here's how.

You can also try rebooting your router to ensure that it is sending out the most up to date network information to your connected devices.

Please let me know if these steps help or not.

I re-added the device and it seems to be working at the moment - I guess we'll see if it disappears again (it had been working fine for months and I didn't move the boost).

New user since December and love it and never had any issues until tonight. The unplugging the missing room component did the trick. Thank you

Hi Henry_123,

Your Sonos system has a high level of interference causing some communication errors. Your missing unit is still communicating wirelessly with your other units, but it's not a strong enough connection for the speaker to stay on the app. Please start by changing the wireless channel your system uses, here's how.

It may also help to update your Sonos system, here's how to do so.

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
