Lost Sonos Connection

I have 3 Sonos S1, sound bar, sub and Alexa S1 and they can not be found by the app. The Alexa App shows them as being there but offline. The Alexa, sub and Soundbar all work as controlled from voice or TV but they can not be found by the app. I have tried reconnecting everything but they can’t be found. I am yet to try factory reset and then seeing if I can set the whole thing up from scratch, as I shouldn’t surely need to do this? Any suggestions please?

I’m not familiar with Virgin routers, but I think the wireless extender may be the culprit. Since there seem to be two separate issues, it’s probably best to contact Support. The voice control problem could even sort itself out once the network setup issue with Sonos is resolved.

Refrain from Factory Reset.

Describe your network. Mfr? Model((s)? Have you recently changed anything?

Nothing has changed since I bought it years ago, except routers, but it worked successfully on the current one for 18months before stopping 3 weeks ago. Standard set up directly attached to router.

​@Martin In York, What exactly isn’t working: is Alexa failing, or is the Sonos system itself having audio dropouts?

If it’s the latter, please answer these questions:  

  • What type of router do you use?  
  • Do you have a Wi-Fi mesh setup, access points, Wi-Fi extenders, powerline adapters, or network switches, and if so, what models are they?  
  • Do you connect Sonos via Wi-Fi, or is any Sonos device wired to the router or a network switch?

Hi I have a standard Virgin Router with one of their own WiFi Extenders. The soundbar and Base works with the TV, as does the Alexa as they can be controlled in isolation, but I have no way of checking the two S1 units. They all appear visible on the Alexa app, but offline so I cannot group them. If I use the app to set up a new system, it cannot find anything and if I use the app to join an existing system, it also fails.  I have also tried reconnecting the units but it can’t find them.

Thanks all. In the end I reset all connections and rebuilt the system and it is back working, with the App.  Not ideal, but I have sound again. Thanks to those who replied, really appreciated
