Thank you for contacting the Intel community.
Make sure the LAN option is enabled in the BIOS, you can just access the BIOS and press F9 on your keyboard to set the BIOS to default settings and then press F10 to save the changes.
If that does not work, try reinstalling the LAN driver manually, you can follow the steps how to do it at the following link:
I suggest you to download the driver again; you can download the driver here:
I hope this can help.
Thank you for your reply, even though I've tried most of that already, I attempted your procedures and got no love from the NUC.
Tried resetting BIOS, no go. Even pulled the battery for a half hour with unit unplugged. Plugged back in, said CMOS time was reset, but curiously fixed itself in a minute or two.
Tried uninstall Driver with removing software, it installed Microsoft Driver, no go.
Manually installed new driver 21.1, no go.
Still says the same thing: Cannot Start This Device (Code 10)
Sadly, I think this network jack is a goner.. any other suggestions would be greatly appreciated, otherwise, it might be warranty time.
At this point, if you reinstall the operating system and you did BIOS update, reinstall the driver manually and if the problem persists, then this is most likely a hardware issue.
I have sent you a private message to help you evaluate your warranty options.
I’m glad that this issue has been resolved and thank you for taking your time to share with us that the replacement solved the problem.
