I have four Play 3 units bought some years ago. I have one attached to my ADSL gateway and it works OK as do the other three.
I now want to use one in my workshop, I have a new, different 5G internet there from TMobile that works fine.
What must I do to be able to use one of the Play 3 devices in my workshop and my other WiFi network?
Is it true that one MUST connect it to the gateway via ethernet in order to do this? I use the Windows desktop app to control Sonos.
