Public bug reported:
I just upgraded from Kubuntu 16.04 to 18.04 and it is most everything
Ok, but -I think that- the network-manager has a problem now.
In the last LTS version I never lost connection through Ethernet (the
only Internet connection with our desktop PC), but the Bionic Beaver
loses the connection every now and then, perhaps within few minutes or
hours, but several times per day.
Only restarting the PC makes the connection to work again.
When the connection is lost, I note that it disappears any info even
mention to any network into the network window and the network manager
icon becomes red color.
