Hello, sorry for the late reaction.
We have discovered, in many attempts, that when you connect the laptop to the docking station, an extra USB-C connection appears. It is this connection that causes problems. You select it and open it with admin rights. You will discover that the power modes are on Idol. That must both set to off.
We did it some week ago and everything is running good.
I'll try to make some screenshots today.

We have the same issues here in the office with all of our new EliteBook 840 G8:
- already did BIOS Updates
- updated all available drivers via HP Support assistant
- issue still exists as connected Ethernet via USB-C Dock G5 AND USB-C to Ethernet Adapterts
- there are no entries in the Windows-Eventviewer
Looking forward for some screenshots of the solution 😃

Hello ICTESS thank you for that however that option Idle Power Saving is already set to disabled Or (Uitgeschakeld) and we are still having the issue with the network dropping. We have found that this is also not just the USB-C dock in the Monitors it also happens with HP's G5 Dock

Thanks for the Screenshots, we did this here exactly as proposed an it works.
As a test, I ENABLED this Power Saving and had the drops again.
It makes sense: It occurs only with the Realtek GbE Chips that are build in the HP G5 USB-C Docks & USB-C Ethernetadapters.
We used an old USB-Ethernet-Adapter from a MacBook Pro with the HP EliteBook G8 and this also worked because it has another Chipset.

The best "solution" I have found for this issues is:
Go to Device Manager > Realtek USB GbE Family Controller > Driver > Update Driver > Browse my computer > Let me pick from a list of available, the top option will/should install v10.5.920.2015
When using the driver from 9/2015 all ethernet issues stop and the dock seemingly works as expected.
We have 300 HP USB-C G5 docks used with ProBooks 450's G7 & G8's and 650's G4, G5 & G8's.
After making the driver change, it just works. The only issue we have on occasion is the Realtek USB Gbe driver will disappear completely and wont show up again leaving the user to wireless or plugging in ethernet directly to the laptop. This has happened on maybe 5 of the 300 we have in use. In those instances, we found the driver showed up again after a couple days. No idea as to why. We reboot, install updates and drivers but it just does not show. Again, this has only happened on about 5 machines.
For the display issues, make sure the dock firmware is up to date and BIOS is up to date. If issues still persist, turn off the laptop then press and hold the power button and F6 for 30 seconds and release. Wait another 15-30 seconds and power back on. That has cleared up any display issues we have had.

So far, on a very limited test, the power settings seem to be helping. Of course, making these changes across lots of devices manually isn't going to fly, so I was able to script it in Powershell - hope this helps someone
Get-NetAdapter | Where { $_.InterfaceDescription -like "Realtek USB GbE Family Controller*" } | % {
Set-NetAdapterAdvancedProperty -Name $_.Name -DisplayName "Energy-Efficient Ethernet" -DisplayValue "Disabled"
Set-NetAdapterAdvancedProperty -Name $_.Name -DisplayName "Idle Power Saving" -DisplayValue "Disabled"
Set-NetAdapterAdvancedProperty -Name $_.Name -DisplayName "Selective Suspend" -DisplayValue "Disabled"
}

I can confirm the very same - its like a "carbon copy" in our case.. New HP EliteBook 840 G8 (product number 3G2Q9EA) - first day out of the box, fresh installed Windows 10 Pro , given to users with new G5 docks (both 26D32AA and 5TW10AA) and it behaves EXACTLY the same - unexpected random disconnecting from Ethernet LAN, sometimes three times within an afternoon, sometimes once a day. All possible updates installed. At first we thought that it is the dock (with the first user), so we replaced it for another.. but no.. then other three reported the very same behavior. It cant be even patch cables or wall sockets because a) iits too many users at once b) in the morning they worked fine on the previous laptpos, get the new ones in the afternoon and after couple of hrs report LAN connectivity issues??
we even tried a G5 dock like a year old just in case that its not a bad manufacture batch od docking stations. The same - random disconnecting from the network. Since HP EliteBooks 840 G8 do not have built-in LAN port can not test it without a dock.

HP released a firmware for the G5 which should help with the issue. As they confirmed, this is just for the G5.
