Sonos constantly dropping out

When rebooting be sure if leave device unplugged for at least a minute.  If there are major problems problems, unplug everything (all speakers, router both power and internet connection, and any splitters)  I use to do a lot of PC and router setup and learned that a lot of settings are not immediately released from cache. 

Same thing for me. Everything has been working just fine and suddenly it all goes to s***, with nothing (knowingly) having changed with our wifi and other network settings. We are long-term Sonos people and have nearly 20 of their speakers and Amps.  It’s wonderful when it works….until it doesn’t and then it’s a nightmare to troubleshoot….

Unfortunately, much of your network can change without interference from you, from updates done automatically to your devices, including your router, to outside influences, such as a neighbor setting up a new WiFi system. It would certainly be nice if networks were a closed system, but unfortunately, that isn’t the way they work. 

I have over 20 of Sonos devices, and an unsupported 5G modem/router/network, and I don’t have any issues, currently. I have, in the past, struggled with a microwave going bad, and bleeding WiFi disturbances, as well as new neighbors, who set up a newly placed WiFi router which interfered with my own signal. 

Sonos, being a networked device, turns out to be as good as the network it is tied to. Given the challenges of networking, some care needs to be taken, it has never been a ‘set and forget’ system. 

This is not fixed and it is awful . Songs don't play Spotify can fork speakers and the songs skip and pause when they do play. It's only play threes for me needs fix asap

It seems many users have the same experience, myself included.  Sonos works great for weeks, then just doesn’t. The service drops when no changes have been to the network or devices, and no updates are available or pending. In the good old days, this did not happen, and it is not happening on other non-Sonos-network devices. I don’t think it’s helpful to blame users for what is occurring. Is anyone at Sonos trying to fix this?  If not, just say so and I will move on to another solution. 

J'ai les mêmes problèmes que tout ce que je lis dans ces échanges, je suis fatiguée de débrancher, rebrancher enceintes, box, forcer l'arrêt de l’appli, et quand même subir ces dysfonctionnements à nouveau le lendemain, ou tout de suite après. Là où ça marche le mieux, c'est quand je transfère le son de mon téléphone sur la roam via Bluetooth ( puis sur tout le système). C'est un casse tête permanent, et ce qui est sensé améliorer notre vie en nous apportant plaisir et réconfort nous apporte frustration et charge mentale…

I have the same problems as everyone I read in these discussions. I'm tired of unplugging and replugging speakers and the router, forcing the app to close, and still experiencing these malfunctions again the next day, or even immediately after. The only time it works best is when I transfer the sound from my phone to the roaming system via Bluetooth (and then to the whole system). It's a constant headache, and what's supposed to improve our lives by bringing us pleasure and comfort is instead bringing us frustration and mental strain...

I have now joined this nightmare. I have 29 Sonos devices and for years I never had the issues that I have read about such as these and now for the last month or so I can’t keep my Sonos system intact. I have factory reset every speaker, recreated my network, wired one speaker to create Sonos net, ensured they are on 2.4 where necessary, turned on or off every router setting that was suggested, rebooted network and speakers a countless amount of times, added AP’s, removed AP’s, and anything else anyone can think off. The system is completely unstable. The most I have gotten out of any of these fixes is 48 hours and then the madness begins again. Sonos has no answers other than reboot this speaker, let’s wire five of th furthest away speakers and send me a diagnostic log. When I do they reply that’s strange. Call me a conspiracy theorist but I believe this is a way for you to retire your products just to upgrade to their newer ones. I’m waiting for them to say to me I see you have three Arcs and three beams. That is really older technology. We have not heard about these issues with the Arc Iltra or the Beam 2nd gen. Have you considered upgrading? F&$k no! My only consideration at this point would be to move to an entirely new company. I have tens or thousands of dollars invested in this infrastructure and now I have to trash it and rebuild somewhere else. This is disgustingly disturbing for so many people to have so many problems, all similar problems and to hear, even other people say it’s your network. It absolutely is not. I am completely fed up with this issue, with Sonos, and with people that standby them and say well something in your network is not right. 

Did you try setting static/reserved IP addresses (see the router's DHCP Settings page) for all Sonos and then powering them all down, rebooting the router and powering them back up?

Yes I have. Every Sonos component has its own static IP and the system has been rebooted dozens of times since they were assigned.
