Here we go again. This time, the script revealed nothing that looked
interesting. Here are some extracts from logs:-

Attempting to wake inactive interfaces (which had seemed to work
previously) did not revive a connection, but there was success when
trying to revive the interface that should have been active (although it
was not the expected address), then another restart brought things back
to the norm:-
