Sonos – suddenly unreliable

We’ve had our Sonos system, connected via wifi, for 5+ years and it’s been rock solid until late January. Suddenly, through no changes to our wifi (router, router firmware, or connected devices) or Sonos system, it started being completely unreliable. This seems to have coincided with the S2 v14 release on 2022-01-25 but that could have been coincidence.

Examples of problems:

  • Speakers would disappear from the controllers (macOS & Android apps).
  • Speakers would stop playing but show as playing in the controllers.
  • Speakers would be playing but show as stopped playing in the controllers.
  • Speakers would not respond to play/stop input from the controllers.
  • Different controllers would show different speakers available.

I did the usual things of restarting the wireless router & restarting the speakers. At the recommendation of Sonos support I changed the wireless channel on my router. All of these worked for 30 or so minutes and then things went sideways again.

Finally, fed up with it all, we plugged a speaker directly into the router instead of having it connect over the wireless thus forming its own separate wireless network. Everything has worked perfectly since then.

This isn’t exactly convenient given where the wireless router is, but our Sonos system is once again functional instead of being a collection of 6 very expensive paperweights.
