I first started creating these connections by reading a page on
freedesktop.org that had the same info as what you now get with "man
nm-settings". The latter might even have existed at the time...

I haven't tested this in a while but in the past you needed one of id and uuid.

The uuid is easily generated with "uuidgen".

There's a famous rant by Linus about having to provide the root
password in order to join a network.

I've never used KDE so I have no idea about which gui applet to use
and how/why settings are saved and I've never used nmtui but I suspect
(unless it was a specific NM bug at the time) that it was a problem
with the polkit settings like Linus' problem.
