We have two Sonos One SL speakers in our salon which we’ve had for nearly 3 years now. Both are on wall brackets set high up. We recently had some bad storms which knocked out power for a few hours. Since then, I have been unable to get the speakers working. I have followed all the recommended steps including restarting the router, factory reset of the speakers, uninstalling the app and even setting up a new group.
When I factory reset the speakers, the app finds them and takes me through all the setup. Once it says it’s added the speakers, I look but no speakers and the app is suddenly unable to find them. Once or twice it’s found the speakers but says they are not registered and wants to take me through the factory reset process again.
What am I doing wrong? They used to work fine, now they either don’t recognise the wifi group or the app or both.
