It is supposed to.

It is supposed to.

There were significant improvements to the connectivity checking
lately. The connectivity checks were previously rather rudimentary,
providing a simple connected/disconnected status, completely oblivious
to the device that's actually used for the check.

With an up-to-date NetworkManager we try to make the connectivity check
use a particular device that has came up and then adjust the route
metric accordingly. We also expose the result on the D-Bus. For this to
work robustly you need to have systemd-resolved available (not
necessarily default), otherwise we're not able to resolve names via a
particular interface.

I'm really really really not going to help you solve eventual problems
on a rather old version when we have a new one that is a drop-in
replacement. On the other hand I'm happy to help if something doesn't
work with an up-to-date version.
