Firstly, what is the exact nature of the issue: Is it the fact that your music is being interrupted, or is your problem that you have rooms missing from the Sonos app?
Commonly, either of these issues can come as a result of wireless interference. Are you perhaps using an incompatible network configuration or hardware that does not meet our system requirements?
If all of the above checks out, you may wish to set static IP addresses to the devices on your Sonos system, some routers have an issue maintaining a connection with devices that remain on the home network.
For information on how to do this, please consult the literature supplied with your router.
As you can see, there are many different aspects to having your system function properly.
If you are still having issues, please start a new topic with the following information:
- What devices do you have?
- Has anything changed on the network?
- Which service(s) are you trying to listen to?
- Is the behaviour always the same?
- Can you recreate it with ease, or is it random?
