I have the Sonos App I just downloaded.  And trying to set up my Play 1s (I have 2 of them).  I’m trying to change the network connection from tethered Ethernet to Wifi.  It’s looking for unit that is plugged in and can only find a sound bar looking unit/ equipment.  Why the heck does Sonos not just make it default to WiFi after set up?  And why is the wifi or Ethernet option so imbedded in the system’s setting?  Should just be able to click on the speaker on the app and toggle from Wifi to Ethernet.  Who the heck is designing the software… user interface sucks!  Not intuitive.   For now I have one speaker tethered to my router.  Sonos is supposed to be wireless?  Ain’t that the big ploy?  Mission?  
 I’m 2 hours into setting up these old Sonos Play 1s.  And still not the perfect outcome.  Have factory reset it 3x… of which, why does it take over a minute of holding down the power button to factory reset?  I miss the days of the pin hole and you just pin to reset.

iIf someone can help me figure out how to change my tethered Sonos Play :1 to Wifi and for the app to find my Play 1 and not find a sound bar that I do not even have on site, I’d love to know.
