Have you tried resetting the BIOS to defaults?
Is the BIOS the latest version?
If you do a System Restore back a week or so, does that resolve the issue?
BIOS is on default and updated (51) - I doubt there's something wrong at this stage since it stopped working while the computer was running. The computer is less than a week old so I don't have any restore points yet short of going back to square one...
Thanks for your advice!
I have this exact same problem. Yesterday the NUC ran all day without hitches. Today, the LAN disconnects every now and then. Same error message "network cable unplugged". The wifi icon also gets a red mark even thou I do not use it.
It's a very new NUC 6i5SYH with BIOS 0051.
I discovered this at MS forum:
Turning off quick boot (or fast startup)
1. Open the control panel and go to power options.
2. In the left pane, look for the "Choose what the power buttons do" option and click on it.
3. At the top of that page, look for the "Change settings that are currently unavailable". You will need administrator access to do this.
4. Under shutdown settings, uncheck the box where it says "Turn on fast startup". Make sure to click on save changes at the bottom.
To apply this setting you have to shut down the computer and boot it up again. Restarting will not do anything.
This is known as a cold boot.

So far my internet has worked since doing this. Would you mind giving it a try and see if this also solves your problems?
Try to reset your home internet router.
Tried turning off fast startup, unfortunately that did not help.
Can't say 100% that this fixed it for me, but I have not had the network disconnect yet since I did it.
If it continues to happen, check the pins in the LAN connector as they can get pushed down and make bad contact.
You can use a dental tool or tweezers to lift them up.
I doubt this is the problem, at least for me, as the wifi disconnects at the same time.
Did you check internet at your home on other computer? Did you reset you router? Because both the wifi and the Ethernet is going off, looks that this is internet reception problem rather than Nuc problem.
This is not a general network problem. All other devices work just fine - ipads, phones, wifi speakers etc. No disconnections.
I'd say a NUC problem or a Windows 10 problem. My fix still works for me at least. No disconnections since last night.
Phone and ipad (if equipped with sim) can get internet connection from mobile data. WiFi speakers are not connected to internet. I don't see any connection to fast startup turned to ON and internet fail (both simultaneously - Ethernet and WiFi).
I see. So your conclusion is: the NUC works fine, everything else is the issue?

If you access the device manager do you see any exclamation marks there?
Does the same cable work OK with other computers?
