Hello, we are asking for help in solving problems with:
INTEL NUC:  NUC11TNHv70L0, purchased on 2/1/2022 from fabrizio orlando, Italy
OS WIN 11 Pro 22H2 - clean installation, BIOS latest - 69, Ethernet Controller latest release 27.8.
We used the NUC unidirectionally - the NUC was connected to the server. There wasn't and isn't a problem with connecting to the server.
By purchasing the monitor, we wanted to use the second LAN port. It is enabled in BIOS. The lower port does not work - after connecting the LAN cable, there is information in the network connections - the network cable is disconnected and the network does not connect. When we connect Lan to the upper port, a connection is established in a few seconds. Win 11 Pro is after a completely clean installation. Before installation, we didn't realize if the lower LAN port worked.
1) we ask for information on how to find out if the problem is in the hardware or in the drivers or in the BIOS

We repeat, Windows is a clean install, without any problems.
Thanks for the solution suggestions.

Dobrý deň, prosíme o pomoc pri riešení problémov s:
INTEL NUC: NUC11TNHv70L0, zakúpené 2.1.2022 u fabrizio orlando, Taliansko.
OS WIN 11 Pro 22H2 - čistá inštalácia, BIOS posledný - 69, Ethernet Controler posledné vydanie 27.8.
NUC sme používali jednosmerne - pripájal sa NUC na server. S požadovaným serverom nebol a ani nie je problém.
kúpiť sme monitora sme chceli využiť druhý port LAN. V BIOSE je povolený. Dolný port nefunguje - po pripojení siete LAN sieť je v sieťových prípojkách informácia - sieťový kábel je odpojený a nepripojí sa. Keď Lan pripojíme do horného portu, za pár sekúnd sa vytvorí spojenie. Win 11 Pro je úplne čistý Stačí. Pred inštaláciou sme si neuvedomili, či dolný LAN port fungoval.
1) prosíme o informáciu ako zistiť či je problém v hardvéri alebo v ovládačoch alebo v BIOSe

Opakujeme, Windows je čistá inštalácia, bez akýchkoľvek problémov.
Ďakujeme za návrhy riešení.

When you say 'clean install', what do you mean? Did you install all of the drivers (except Intel RST) that are provided via this page:


Yes, all drivers installed except RST.

We need more information on the environment. Please download and run the Intel System Support Utility for Windows. When you start the tool, select Everything and then click on Scan. Once it completes the scan process, click on Next and then Save. Pick a name for the text file to create and click on Save to create it. You can then close the app. Finally, open a response post here and then, using the Drag and drop here or browse files to attach dialog (below the edit box for the body of your response post), upload and attach this text file to the response post.

Also, are you seeing the LEDs on the LAN port turning on when a cable is plugged in?



Hi, Scott, yes, the LEDs flash both in the upper port and in the lower one, after connecting the LAN cable. I also noticed that the new BIOS is 70. I'm going to install it and report back. Thank you for your willingness and understanding. Best regards Jana


BIOS new 70, did not help. The LED flashes, but the port is not found in the control panels. It's only the upper one and it reports a disconnected cable - which is true, because the cable is in the lower port. Once we switch the cable to the top port, the network works fine. Jana


Hello JAGUAR2,

Thank you for posting on the Intel® communities.

I am sorry you are having issues with your Intel® NUC11TNHv7. I will be glad to assist you.

We appreciate the troubleshooting steps already performed as well as the information provided. In order for me to investigate about this issue, please uninstall the current Ethernet driver and re-install the driver version 27.4 ( and let me know if the issue persists.

Best regards,

Steven G.

First of all, if there is no cable plugged in, it is normal to see the error message in the Network Status.

As for the lower connector, it feels to me like you have a failure occurring on the Secondary Network adapter card. Since you purchased the NUC with this card installed, you should look at having the entire unit replaced. You can attempt this through the storefront where you purchase the unit or, of not possible, via Intel's RMA process.

For the RMA process, after verifying that your warranty is still active (here: Determine if Your Product Is Still Under Warranty), you need to directly contact Intel Customer Support to initiate the RMA process (you cannot do this through the forums). You can start here: Contact Intel Support or use this page where you can directly look up local/country phone numbers: Intel Support Phone Directory.

You can also use the online forms service or email, but I actually recommend calling Intel directly. The above link provides local or toll-free numbers for most countries and these numbers support most local languages. You could also use the chat service (start here: Intel Customer Support Chat), but understand that this service is offered only in English and is subject to the normal (9:00-5:00 M-F) office hours in the Pacific (UTC-8) time zone.

Hope this helps,
