Did something change or has it "always" been like this? What about other 
systems on the same network (if any).

How / where did you check? What is the difference in the logs between 
reboot and disconnect / reconnect?

In case it helps, 'journalctl --unit NetworkManager.service' will filter 
entries (need to be root or member of 'adm' or 'systemd-journald').

Is this with DHCP or static IP? If DHCP, can you tell us more about the 
DHCP server (device, software, etc.)? It might be useful to check the 
status / logs / etc. there if you have access.

Does it still happen if you switch to a static config?

Hope this helps,
