Sonos One SL Disconnects Monthly

I’ve had Sonos speakers for over a decade so am well versed in issues and resolving them. That said I am at a point with a relatively new Sonos One SL (Oct 2023) where I’m close to ditching the thing. 
 

Almost every month, for no reason we can fathom, it disconnects from the system and I have to go through the entire factory reset, setup from scratch. It’s the only thing that works. Even then I often have to do this several times until, again for no obvious reason, it returns to the system. 
 

the other speakers are and have always been rock solid - two ancient Play 1 and a very old Playbar. This sound familiar to anyone - any help would be appreciated.

My suspicion would be some sort of IP release / regrant issue, caused by some sort of problem in your router.

The first thing I’d do is check the router for updates, and apply any that are found. Then I’d unplug all Sonos from power, and reboot the router, giving it a couple of minutes to come back up. Then I’d plug back in the Sonos devices and let them boot up and connect. 

This will provide lots of things, any one of which might ‘fix’ your issue. In the meantime, I’d consider looking in the router’s manual on how to reserve IP addresses in the router, which more permanently does one of the things that the above process does. 

But, if that doesn’t resolve the situation, the next time you ‘lose’ that speaker, I would recommend that you submit a system diagnostic within 10 minutes of experiencing this problem, and call Sonos Support to discuss it. But don’t post the resulting diagnostic number here, they 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.
