Hi Everybody

I have a pc laptop thinkpad lenovo with opensuse gnome 13.1 onboard (64 bit machine).
When I get disconnected from the network for a while, disappear the wired interface enp0s25 and i have to restart my laptop to re-connect to the wired network.
This wired interface (I mean the enp0s25) is configured with “auto” startmode , maybe I have to set it to ifplugd mode?
Furthermore, there is a timeout that bring this interface down and consequently it forces the pc to restart?
Thanks for all your advices.

I’m using NetworkManager.

As far as I can tell, it is normal. NetworkManager deactivates interface on link down event and should activate it again on link up.
