What have the system logs (dmesg, /var/log/syslog, /var/log/messages --
or whatever equivalent there is in the systemd world) to say?

Perhaps you can find a correlation between the (dis)connects and some
log activity?

Sometimes a flakey cable (they *do* exist) or flakey network hardware
show such symptoms. To give you an idea of what to watch out for, I
just did

  tomas@rasputin:~$ sudo tail -f /var/log/messages

and then pulled my eth cable out of the laptop and re-inserted it. This
is what the log shows:

  Jan 21 12:59:44 rasputin kernel: [14423.324311] r8169 0000:02:00.0 eth0: link down
  Jan 21 12:59:47 rasputin kernel: [14426.188524] r8169 0000:02:00.0 eth0: link up

But of course, NetworkManager has been seen acting up too, from time
to time (the last time it did it for me it got a perpetual ban from
my boxen, but that's a while back. Reportedly, it got better).
