I am using 3x MA2500Ds (v2.0.16) on the trunk of a Unifi network between 2 managed switches and an AP.
The MoCA adapters were assigned DHCP leases, and their management pages are accessible, but my network controller shows them as "offline".
When power cycled, they will be "online" for about 5 minutes, then appear as "disconnected" again.
Sometimes (1-2 times per day), they will appear "online", but appear as "disconnected" after ~5 minutes.
Their connected devices can communicate, but it's concerning that the adapters themselves are not "online".
Perhaps there's a bug in their ARP implementation, or something else?
