I purchased my first Sonos speaker, Play: 5. I plugged it into the router and followed set up instructions. Entered my wi-fi network and password. Received message that Sonos was now connected to my network. Played music. As soon as I unplugged the speaker from router, the speaker tried to connect and could not. I have tried all suggested fixes. Restarting router, Advanced Setup, nothing works. The speaker will not connect and play music unless it is plugged into router.
