If a network message pops up regularly notifying that no connection could be established, then this can be mitigated by disabling the ipv4 connection and setting the ipv6 connection to local only.
Open the settings from the system drop down
Then select the network settings tab
Select the USB network adapter called "enx..." The image is missleading as it was taken on a VM with no such (USB) device.
Disable IPv4 in the IPv4 Tab
Set IPv6 in the IPv6 Tab to Link-Local only
