Hello there,
I have a Sonos One and a Sonos SL connected to the router downstairs and all is super there.
i purchased another Sonos SL for the bedroom which operates on a different router. I connected and it worked but as soon as the email connection drops (happens fairly regularly) or a power cut this Sonos needs resetting. It just doesn’t seem happy to be on a different router. I try to control from my iPhone but sometimes it shows the speaker, sometimes not. I have factory reset to get it to work but just not happy. There must be an easier way. Do I need another piece of kit or a different Sonos?
