I have two Linn systems at this location, Linn Klimax DSM for the main music system and Linn Kiko for the AV setup. They are wired via Actiontec MoCA ethernet-over-coax to an Ubiquiti EdgeRouter PoE-5. This morning I updated the router to the latest firmware. Later in the day, Roon could not find the two Linn systems, although it had no trouble finding a Ropieee-based endpoint. Checking further, Linn Konfig could not find them either. Power-cycled both Linn systems, they are both back. I’m surprised that they could go AWOL this way, but I could have wasted a lot of time fiddling with Roon if I hadn’t tried Konfig right away. Beware…
