Ethernet port broke?

Intel NUC NUC8i5BEK Mini PC/HTPC, Intel Quad-Core i5-8259U Upto 3.8GHz, 16GB DDR4, 1TB m.2 SSD, WiFi, Bluetooth, Thunderbolt 3, 4k Support, Dual Monitor Capable, Windows 10 Pro (16GB Ram + 1TB SSD)

Bought new, Jan 2019

1. Wired connection stopped working two days ago (Ubuntu 18.04) Box has just been sitting there.

2. Booting into Windows, still broken

3. Connecting another computer to the Ethernet cable, works.

If this means the Ethernet port broke somehow, can I 

1. Fix it with a part?

2. Find another way to fix it.

Don't really want to do a USB to Ethernet adapter as I have no free USB ports.

Other thoughts? Thanks

Hello Ophitoxaemia

Thank you for posting on the Intel® communities.


In order to try to fix this issue, please check that Ethernet LAN is enabled in BIOS:

  1. Press F2 during boot to enter BIOS Setup.
  2. Go to Advanced > Devices > Onboard Devices.
  3. Check the box to enable LAN.
  4. Press F10 to save and exit BIOS.

You might see this as Primary LAN and Secondary LAN on some Intel NUC models.

We undestand you tested the cable on another computer; however, just in case, please try to test the Intel® NUC with different Ethernet cable.


Since you already tested Windows® operating system, please install the latest Ethernet LAN driver available on Download Center for the Intel NUC, Version: 24.3 >> https://downloadcenter.intel.com/download/28965/Intel-Gigabit-Ethernet-Network-Connection-Driver-for...


For UBUNTU® drivers, please kindly refer to the UBUNTU® community or Operating System provider to get the most updated drivers.


If the issue persists, please install the latest BIOS available on Download Center for the Intel NUC, version 0083 >> https://downloadcenter.intel.com/download/29798/BIOS-Update-BECFL357-86A-

Please see BIOS Update and Recovery Instructions for Intel® NUC with Visual BIOS for instructions, we recommend using the "F7 Update" method:

https://www.intel.com/content/www/us/en/support/articles/000005636/intel-nuc.html


If the issue stills persists, try a BIOS recovery using the BIOS Recovery by Security Jumper method. The instructions for this process are included in the BIOS Update and Recovery Instructions link above.


If none of the previous steps solves the problems, this most likely means that the hardware portion of the LAN Subsystem (Ethernet controller and RJ-45 LAN connector) has failed. The components are integrated/soldered to the motherboard and they are not available as a spare part/fulfillment.


In that case, our recommendation is to contact your place of purchase or to reach out Intel® Customer Support through phone or chat and review warranty availability for your Intel® NUC. Here is the "Contact us link": https://www.intel.com/content/www/us/en/support/contact-support.html#@7

Please make sure to select your country or region and to contact us within your local business Support hours and to make reference to this thread.
