I have the same problem on my desktop running Ubuntu 18.04, 18.10 and 19.04
with standard kernel and also in 19.04 with last mainline kernel. I don't have
windows on my PC but multi-boot with other Ubuntu partitions.

Title:
Intel I219-V Ethernet Interface on Ubuntu Linux Using e1000e Driver
keeps Dropping Internet Connection
Status in linux package in Ubuntu:
Confirmed
Status in linux source package in Bionic:
Confirmed
Bug description:
I've turned up many, many new server and workstation systems over the
years on both Linux and Windows. Never seen anything like this
behaviour I'm witnessing on Ubuntu Server 18.04 before where I simply
lose Internet connectivity while using a browser. Ethernet interfaces
usually either work or they don't work.
I've configured the Intel I219-V Ethernet interface (wired Ethernet
connection, there is no wifi on this system) using the e1000e driver
for Ubuntu. The Ethernet connection is configured to use
NetworkManager via Netplan on Ubuntu 18.04 LTS Server version. ASRock
Z370m Pro4 motherboard.
The Ethernet interface will drop the Internet connectivity when I'm
using either the Firefox or Chrome browser. It usually happens when
I'm using the search features of the browser. I can't figure out what
would cause this type of behaviour. When the Internet connection
drops, the only way to get back Internet connectivity is to disconnect
the wired connection using the Ubuntu features and then re-connect
(this restarts the NetworkManager service I notice).
In the NetworkManager logs I do notice an "auth" error about a file or
directory not found. I've never seen that before.
Note: The auth error does not coincide with the loss of Internet
connectivity, but it does proceed it. Often there can be many hours
between the auth error and the actual loss of Internet connectivity.
After I reconnect the connection (via re-starting the NetworkManager
service) all will be fine for up to a day or so, but then I stress
test it with a bunch of searches using the browser and usually I can
get the Internet connectivity to drop again. Repeat the disconnect
and reconnect process again (aka re-start NetworkManager) and the
Internet connectivity will be fine again. The longest I've seen it go
without an "Internet connectivity drop" issue is about 36 hours.
I notice that the e1000e driver does not list the I219-V as a
supported Ethernet interface in the Intel documentation for the Linux
version of the driver. I'm not sure why that is. The I219-V is
supposed to used another driver, but it's not clear there's a Linux
version for of the driver for the I219-V.
I'm really disappointed that I've run into this issue with Ubuntu
Server LTS 18.04 on this motherboard. I had CentOS Server 7.4 (my
standard server OS, a great Linux distro) on this same motherboard for
a week with no issues, so I know the motherboard and the I219-V
Ethernet interface are 100% good hardware wise and can work properly.
CentOS 7.4 uses NetworkManager as the default for managing the
Ethernet interface.
The only reason I'm using Ubuntu Server 18.04 on this motherboard is
because of a specific package that Ubuntu has a newer packaged version
than CentOS. CentOS is extremely stable when it comes to basic server
functionality.
Hopefully, this bug with the I219-V Ethernet interface using the
e1000e drive for Linux can be verified and a fix rolled out.
