We use our Roam to play white noise in our daughters room. The speaker is set up in her room on the wireless charger. Previously it always worked fine, and then now it randomly just drops out and appears as “not connected” in the Sonos app. It’ll play for an hour or so, and then it disappears.
Hard rebooting the speaker via the button on the back returns it to the app and makes it usable again, but it’ll play for another hour or so and then randomly stop and disappear.
For reference: my home sonos system runs on Sonosnet channel 6
