It’s possible that due to the recent update, your router may have assigned duplicate IP addresses to some or all devices. Have reserved IP addresses been set up in your router?

If not, there is a simple, albeit not permanent thing you could try, by unplugging all Sonos devices from power, and then rebooting your router. Once the router has come back up, plug the Sonos devices back in to power, and wait a couple of minutes before you test.

If that works, I’d recommend that you check your router’s manual and figure out how to reserve IP addresses for all your network device, it’s a more permanent way to avoid a recurrence if this issue.

Thanks for the response. The system has improved, but speakers still drop now and then. I’ll see if I can find out how to reserve IP addresses on my router.

I needed to refer to my router’s manual originally, but there are others who have found video instructions on youTube to be successful, depending, I suppose, on the router model, and the person who made the video.  

The challenge is that from model to model sometimes, and definitely from manufacturer to manufacturer, that process is different.

I have a recent Xfinity router, and I cannot find a way to assign static IP addresses, unfortunately. Their website offeres plenty of canned answers for simple questions, but not this. Their chat is a bot that spits out the same unrelated nonesense over and over. Waiting on hold for 40 minutes to talk to a real person is not a possibility.

See this video (it's for Airscape devices, but it's the same steps for Sonos).

 

 

Note, default username/password for xfinity routers is admin/password.  Also, to find the Sonos devices, match the serial number under Settings > System > About My System in the Sonos app to the MAC addresses listed in the Xfinity settings.
