Same as Ed C, My Connect suddenly dropped off the list of ‘rooms’ and will no longer connect to wifi or via ethernet. It will not ‘reboot’ by on off or by switching on whilst holding pause button. When switched on, the white light comes on for approximately 4 seconds then goes out. Nothing else happens. It gets warm, The rear digital out port has an active red light showing inside but the Connect remains unseen by the system. I have rebooted my router. My other sonos speakers all continue to work fine. Has anyone else had this problem and is there a known remedy please?
