I've only had my Aura for a couple of weeks, but it has so far disconnected from WiFi on at least 2 occasions while on Standby. This obviously makes any remote operation impossible, such as scheduling new recordings or viewing/downloading existing ones.
My Aura is in the same room as the router, 4 meters apart with line of site. It is a modern WiFi 6 router and I have no problem with connections to any other devices.
The Aura reconnects to Wifi when I take it out of standby, and resumes normal service.
Is this a known or common issue? Any workarounds? I could potentially buy a new powerline adapter and connect via ethernet cable - but why should I?
