           Summary: NetworkManager does not reconnect if DHCP server
                    disappeared
    Classification: openSUSE

If the DHCP server disappeared for some time while the lease needs to be
renewed the interface is marked as failed.

I have a DSL router which acts also as DHCP server for the local clients.
Its lease time is set to a short renew time.
This DSL router is connected to a switch which has power all the time.
My laptop is also connected to this switch.

If the DSL router is powered off for a few hours, NetworkManager (or whatever)
marks the interface as failed even if the local link does not go down.
Even if I unplug the cable and plug it in again, the interface will remain
inactive.
I expected that on a replugin the interface can be used again.

In addition, instead of marking the interface as failed, there should be some
polling. Maybe the DHCP server will come back after a while. Then the network
connection can be reestablished and connectivity comes back automatically.


I will attach some logfiles.
