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.

Have the same problem. Just started. Lost the living room with the bridge and two L1 sides. Completely disappeared. Diagnostic number 6155037.

Unplugged bridge and plugged back in and the Living Room reappeared. 🙂

Hi AmericanSwede,

There are high levels of wireless interference showing. Please try changing your system's wireless channel, here's how.

After changing the channel, wait a couple minutes and see if the missing player returns. If not, try rebooting the player by removing it from power for ten seconds. It may also help to reconnect the speaker through this process.

Hi Waggers5009,

There isn't too much interference showing on your diagnostic report. Please follow these steps to reconnect your missing unit. It is possible that range is a factor. How far is the missing player from the nearest Sonos unit? Which unit is closest to the missing player?

The closest unit is just a connect box and is approx 15 metres apart, it was showing and working but has disappeared. I have tried removing power and adding but keeps saying it has already been set up, can I get into back to green light and start again? Thx

There is a unit showing in your diagnostic report which has no IP address. This may be the missing unit. It has a very weak wireless connection to the Kitchen and Lounge units. Is it possible to move the missing unit closer? Try that and see if the missing unit reappears. If so, it may be a range issue.

It's reappeared but the speaker connection is to far away, is there a way of boosting the signal between the boxes? Thx

Each Sonos unit sends out a signal, so you can use a Sonos unit in between to provide a wider coverage. If you don't have an extra speaker you would like in that area, you can use a BIRDGE or a BOOST instead.
