I have a comprehensive Sonos system with around twenty components. No issues with connectivity on any of them, except for one Play 5 which dropped from the system. I reset (numerous times at this point) and could not get it to reconnect wirelessly (could not join the temporary Sonos network). When I connect via ethernet it finds it right away and speaker can be set up. I have even been able to disconnect the cable and have it remain functioning as long as I don’t unplug the speaker. Once I unplug it to move it to its preferred location, it can no longer be found (wifi range is ample). Sometimes when I unplug it it will immediately lose connection.
