Era 100 & Sub Stereo Pair dropping

I have had a Beam with Ones in a stereo pair working rock solid for a few years. I also have a Five and a Move 2 and have had no issues at all. 

I’ve just added 2x Era 100s and a Sub mini to my setup. The Era 100s are in a stereo pair with the sub in one room (my office)

At least once a day, the stereo pair drops/breaks down, with music just coming from one Era 100. The only way i can get it back together is to power cycle the speakers. I use the Sonos app mainly to play music but occasionally use Airplay and my Connect+Turntable. I’ve not noticed any cause+effect with the chosen source and stereo pair drops.

My office has the router located in it, so the wifi signal is full strength. I have no other issues with my network or speakers.

Any ideas why this is happening and how i resolve it please?

That suggests, although doesn’t guarantee, some wifi interference . Which could come from ‘outside’ your network. Just as a precaution, the first thing I’d try is a network refresh, by unplugging all Sonos devices (not merely the Era 100s), and then reboot the router. Give the router two minutes to come back up, then plug back in your Sonos devices. Give them a couple of minutes to boot and connect, then check in your controller for updates, and apply them as necessary. Finally, do your testing.

If the above process doesn’t fix the issue, I would recommend that you submit a system diagnostic within 10 minutes of experiencing this problem, and call Sonos Support to discuss it. Don’t post the resulting diagnostic number here, their lawyers get sensitive about GDPR.

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 Support staff, they have tools at their disposal that will allow them to give you advice specific to your network and Sonos system.

Too close to the router? They are pretty high power so a Meter would be the minimum distance I'd want them apart.

Under the network section for each speaker what does it show for the signal strength and connection quality?

Thanks Stanley - there’s a good metre between router and the speakers. Both show ‘strong connection’ to my 5hz network. I’ve also assigned them static IP’s but the issue still occurred last night.

If you did the power down, reboot router and controller, power up after the assignment about all that is left is the support call suggested above
