If a machine is upgraded to 16.04 (rather than fresh install) then I
believe that it stays with the ethn device names (at least that is my
experience).  Also the fact remains that if all works well when the
router is in a known good state but problems start when the router is
in a known (but unknown) strange state then suspicion must surely fall
primarily on the router. It appears to me that there is no evidence
that there is anything wrong at the PC.
