Public bug reported:
>From time to time the wired connection is no longer accessible for a few
minutes while network-manager always sees it active, even when I
disconnect / reconnect from the applet. To recover the connection,
either I wait a few minutes, or I unplug and then reconnect the cable.
The other devices connected to the router have no issue and despite new
network cables, only the computer under Ubuntu is affected (the same
with the r8168 driver)
