I have a love/hate relationship with the Linux NetworkManager daemon.  It usually works and keeps your laptop PC network connections going smoothly when you move around, but it gets in the way when one does network tests and system integration using a laptop PC.

This is especially important in small countries which are subject to the political whims of the big five, who can make you wait indefinitely f
