I changed my router so I reinstalled my two Play 1s. That was all fine, but now both devices stops playback after about 2-3 minutes from Spotify and after that the Sonos devices cannot be detected from any app including the Sonis app. I can unplug and plug them back and then play some minutes again before playback stops. This happens from iphone/Android/Ipads/computer.
I have installed my Sonos devices on a 2.4 Ghz that is set up to be compatible with the, now, old, Sonos devices.
