I'm just trying to figure out the simple case for now: single user who is an admin. I'm experiencing undesirable behavior. If this simple and common case isn't working out well, then I don't expect the more complex cases to work out much better. And as an ape who wears pants, I try to limit how confused I get in a given time frame.

Is Gnome > Settings > Network leveraging Network Manager? If so, it's using a different naming convention than systemd, and it seems the two are involved in some non-deterministic confusion.
