Minim server regular crash

[TeeJayPee]

The connection to our router is via Devolo home plugs.

I had always assumed the Devolo home plugs were a passive network component.

For information, the router that manages our network is a Draytek Vigor 2120, so not a new device. It has been the router since the creation of our network. I followed the Linn advice of the time to employ a router cascade; intended to remove streamer troubleshooting from Internet provider troubleshooting, I believe.

We have used MinimServer for a long time, maybe since 2010 or so.
These crashes started sometime last year, then suddenly seemed to stop.
I did not manage to relate the start of crashes nor the apparent end of crashes to an update of MinimServer or NAS firmware.

Devolo home plugs have been in use since the purchase of the streamer and music NAS.
