I have a Sonos One that works fine if I have it in the main room of the house. When I move it to a different room, however, it doesn’t show up as an available device in the Sonos app. Could it have something to do with my wifi setup? I have a Netgear Orbi system with 3 Orbi satellites. The main Orbi router is in the living room next to the stereo system. The Sonos One works fine in that room, but when I take it to a back bedroom (close to one of the Orbi satellites) and plug it in, the device doesn’t show up in the Sonos app. It seems to only work if it connects to the main router and not to one of the satellites.
I also have a Sonos Connect, which is connected to the stereo in the living room. It shows up in the Sonos app from any room in the house.
