I often have trouble with the new app connecting to our system. The app also randomly adjusts the volume of our speakers and sometimes removes speakers from groups. I’ve tried using the system update option in the app but that has not corrected the problems.

It is possible that you may be experiencing, at least in part, some duplicate IP address issues, although fixing that would help only some of your reported issues. 

Try unplugging all Sonos devices from power, then reboot your router. Give the router a couple of minutes to reboot before plugging back in your Sonos devices. Give your Sonos devices a couple of minutes to finish their reboot/reconnect sequence before testing.

If you continue to have issues, submit a system diagnostic within 10 minutes of experiencing this problem, and call Sonos Support to discuss it.

There may be information included in the diagnostic that will help Sonos pinpoint the issue and help you find a solution.

When you speak directly to the phone folks, they have tools at their disposal that will allow them to give you advice specific to your network and Sonos system.


Thank you Bruce. That seems to have worked. I followed your instructions this morning and have had my system playing all afternoon without any issues. I appreciate your help!
