long story short afaik: if the networked connection went away (hibernation, modem/router/lan fault, etc.) the machine is unable to connect again unless it's been rebooted.
Usage / Scope of the machine: pi-hole + torrent box.
The machine: I've done a fresh install on a not-so-new small laptop/netbook with a new ssd drive, because the old hdd with win7 and deb9 went away; with deb9 I didn't have such problem, I'd like to use deb10.
Linux / Debian know-how level: borderline beginner, search engines friendly, I put random command on the shell hoping not to destroy the world.
