NUC8i7HVK - ethernet adapters disappeared (not in device tree as disabled, but completely gone)

Hi,

Shortly after a BIOS update that removed legacy boot, my ethernet adapters disappeared from the device tree. The driver install does not detect them, they do not show up as other device, and I do not get a link light when I plug a cable into either jack (which is connected elsewhere). They are enabled in the BIOS. I tried clearing the CMOS battery and also resetting the BIOS by removing the jumper. When I remove the jumper and boot, during the 'reset' I get activity lights back on the ports for a short moment, then the BIOS is reset and they turn off. Even while I am in the BIOS I do not get activity lights, and the ethernet adapters are clearly checked as on in the bios. Any ideas?

1. Enter BIOS (press F2 while booting). Press F9 (confirmed by "Y") to set BIOS to default settings. Now press F10 (followed by "Y") to save the settings and exit to Windows.

2. In the search box on the taskbar, type Network troubleshooter, and then select Identify and repair network problems from the list of results. Follow the steps in the troubleshooter and see if that fixes the problem.

3. If that doesn't fix your connection problem, try these things: https://support.microsoft.com/en-us/help/10741/windows-fix-network-connection-issues https://support.microsoft.com/en-us/help/10741/windows-fix-network-connection-issues

Hi Leon - I should have mentioned I'm an engineer on the Windows OS - I've tried all three. The devices aren't being enumerated by the OS.

Thanks

Here's some info about the PCI bus:

I can't see, for example, 8086:15d5 which would be the I219-LM. I think it might be an issue under the PCH?

Hi ianhan ,

Probably in Windows you are expert more than I'm. I've have long experience in RT S/W. So, I understand that you know how to fix network problems in Windows. I've some other suggestion to try:

1. Enter Bios Advanced>Devices>Onboard Devices and remove the check mark (disable) LAN.

Press F10 to save the setting and reboot the NUC to Windows.

Shut down the NUC.

Switch the NUC ON and enter Bios Advanced>Devices>Onboard Devices and check (enable) LAN.

Press F10 to save the setting and reboot the NUC to Windows.

2. I assume that you have updated Bios by pressing F7 key. If I'm right, please try to update Bios using Bios recovery method - with Security Jumper removed: https://www.intel.com/content/www/us/en/support/articles/000005532/mini-pcs.html BIOS Recovery Update Instructions for Intel® NUC

3. If the above suggestion will not help please download Intel System Support Utility: https://downloadcenter.intel.com/download/25293/Intel-System-Support-Utility-for-Windows- Download Intel® System Support Utility for Windows* , Run it, and save the generated by this tool report. Attach this report (press Attach in the right bottom corner) to your post. Intel support agent will always ask for such report. This will save your time for getting support from Intel.

Hi Leon,

Tried:

- Update from within bios UI

- Running BIOS update .efi from UEFI shell

- Removing jumper and updating using text UI

- Using the auto-flash from USB method

Unfortunately no luck. I also tried disabling nic, shutdown, enable nic, and boot to Windows. No luck. I kind of wonder if I messed up much earlier somehow.

EFI shell can't see the devices matching the nics vid/pid via pci/device lists.

Report attached.

Thanks for your help Leon!

Hi,

I was looking into the report you sent. I see that you have active an TAP-Windows Adapter V9. I think that after disabling/removing this adapter your network adapter should work again.

Hey Leon - I can't find that in the adapter list or the log - can you check the log again, or paste the part that has it?

Thanks again

Hi Ian,

Sorry for misleading you. I was looking in somebody else report. saved on my computer. You are right, in your report there is no network adapter (have to be two adapters). The best way to see this report is not in editor, rather open the text file in the SSU (the Intel tool). You shall use the Detailed View. You can download such report send by other NUC8i7HVK user and compare to yours (see the Networking section).

In my opinion, the network adapter in your NUC failed and you shall replace your NUC. You can do this in the place of purchase or issue request fir RMA to Intel: https://supporttickets.intel.com/warrantyinfo?lang=en-US Warranty Information

https://www.intel.com/content/www/us/en/support/articles/000005679/mini-pcs.html Warranty Information for Intel® NUC Products

Any way, today may be you will have some other advice from Intel Support Agent.

Leon
