That's the right driver. One thing you could try is after removing the
module, try "modprobe r8169 debug=n" where n is a number up to 16. That
will give you more debugging info in the log. Careful, 16 might really
spam the log, so maybe start at 8 and work your way up.

The driver is saying that there is no link detected. Are the lights on?
What does "ethtool enp4s0" tell you?

This one looks like your network card, but you don't want ModemManager
doing anything with it anyway.
Looking further into the log files, I don't seen any mention of r1869
before March 17 when I tried to make a change to the boot parameters
from something I found on the net which was almost a month after the
problem started.
pci=nomsi,noaer
I would suggest removing this.
My guess, given that reloading the driver makes it work again, is that
after resume, the driver is not turning some part of the chipset back
on. Maybe the interrupts are getting turned back on.

What does "grep r8169 /proc/interrupts" give you when the interface is
working? Try it a couple of times and see how the numbers change. Then
when it's not working try it again a few times and see if the numbers
are still changing.
