NUC7PJYH BIOS [JYGLKCPX.86A] 0037 broke my ethernet card

Hello

I just wanted to warn you that the bios 0037 doesn't run the network adapter.

I put the 0027 and works well as before

Someone with my same nuc (NUC7PJYH) could give me confirmation of what has been said?

This is for the NUC7CJYH, NUC7PJYH, and NUC7CJYSAL, for those that do not recognize the bios string.

I've downloaded from here :

https://downloadcenter.intel.com/download/27771/BIOS-Update-JYGLKCPX-86A-?v=t Download BIOS Update [JYGLKCPX.86A] the JY0037.bio file and in release notes says : PRODUCTS: NUC7CJYH, NUC7PJYH, NUC7CJYSAL (Standard BIOS)

And i can confirm that the ethernet doesn't work.

Downgraded from here https://downloadcenter.intel.com/it/download/27563/Aggiornamento-del-BIOS-JYGLKCPX-86A-?product=126137 Download BIOS [JYGLKCPX.86A] the JY0027.bio and now my ethernet card still working fine.

So i repeat : I have the NUC7PJYH2 (2=European) and with the bios 37 the ethernet card is broken.

Stefano,

I just upgraded to BIOS 37 on my CJY and I am having absolutely no issues using either the Ethernet or Wireless interfaces. You need to look into what Ethernet package is installed under Windows and upgrade if necessary. Here is link to latest package: https://downloadcenter.intel.com/download/27467/Realtek-Gigabit-Ethernet-Network-Driver-for-Intel-NUC-Kit-NUC7CJY-NUC7PJY?product=126137 Download Realtek* Gigabit Ethernet Network Driver for Intel® NUC Kit NUC7CJY, NUC7PJY.

Hope this helps,

I can confirm that BIOS 37 breaks ethernet on my NUC7PJYH running Ubuntu 18.04. After updating the BIOS, the ethernet entry is gone when executing ifconfig on the command line. Pulling and reinserting the connector does not help. Neither does disabling and then enabling ethernet i BIOS.

I'm going back to BIOS 27.

EDIT: Ethernet is back in working order now after downgrading to BIOS 27.

Have any of you tried the driver Scott provided the link to?

No, sorry. I'm running Ubuntu 18.04, so that's not going to work. I know you don't officially support Linux on this thing, but it's still rather unusual to have a BIOS update break functionality in this way.

And how about you, fatez? Windows or other?

You will note that only windows 10 is supported: https://www.intel.com/content/www/us/en/support/articles/000005628/mini-pcs.html Supported Operating Systems for Intel® NUC Products

I just finished installing windows 10 on a second ssd and confirm that the network is not seen.

Hhmmm, as I said, I updated the unit I have access to and it didn't effect LAN or WLAN access at all; both are working just fine.

Look, you shouldn't have to do this, but over the years I have seen issues where the BIOS configuration does not work as expected after upgrading the BIOS. Try doing the following:

  1. At the BIOS splash screen, use F2 to enter BIOS Setup (the Visual BIOS program).
  2. Use F9 (followed by Y) to reset the BIOS Configuration to defaults.
  3. Use F10 (followed by Y) to save this configuration and exit BIOS Setup.
  4. At the BIOS splash screen, use F2 to again enter BIOS Setup.
  5. Make any changes to the BIOS configuration that you require (boot order, NUMLOCK state, etc.).
  6. Use F10 (followed by Y) to save this configuration and exit BIOS Setup.
  7. Boot into Windows (or Linux) and see if the Ethernet solution is recognized.

Hope this helps,

Scott,

Did you run the Windows BIOS update utility or use the F7 method? Just got confirmation from another NUC7PJYH owner that his ethernet works fine after updating from Windows, even without loading default settings afterwards. Both me and fatez have used the F7 method and can't get it to work.

I may be able to attempt updating from Windows on Friday. Fatez, maybe you can try the Windows method and report back?

I never, ever, ever use the Windows-based BIOS Update utility -- and I recommend that you do not either! I have seen it brick units, so I do not trust it at all.

I updated my BIOS using the F7 method. If it does not work after doing it via the F7 method, reinstall the BIOS again, but this time use the jumper-based BIOS Recovery method.

So, it is safe to say you are not a fan of the Windows-based bios update?

Doc (who does not use the Windows method)

Yeah, I stay away from Windows based BIOS flash utilities for the same reason.

Okay, then I can spare myself installing Windows. I'll report any progress (or lack thereof) on Friday.

@brunnis, just reflashed the bios and the networks works fine now... try this : /etc/netplan/01-netcfg.yaml

network: version: 2

renderer: networkd

ethernets: eno1:

dhcp4: yes

sudo netplan apply absurd that intel has changed device from enps0 to eno1

See here :https://wiki.ubuntu.com/Netplan/Design https://wiki.ubuntu.com/Netplan/Design

Discovery (Subiquity)

Cathy boots the latest Ubuntu Server Image on her Intel NUC via USB key. The NUC has both a wired ethernet port and a wireless NIC builtin and has added a third USB-NIC as well, though it's not currently connected. During the installation, the installer presents Cathy with the 3 interfaces. Cathy selects the wired ethernet device; it was the only one with an IP configured via DHCP. After the installation is complete Cathy reboots her NUC and finds the following in /etc/netplan/01-install.yaml:

network: version: 2 ethernets: # configured by subiquity eno1: dhcp4: true

The installer wrote out a config which included elements for the explicitly chosen/configured wired device. The other NICs are unconfigured, as the installer should not make any assumptions about their future usage or configuration.

Wow fatez! That actually worked! That would have taken me a while to solve... :-D Thank you so much!

Just a note: It's important to get the contents of 01-netcfg.yaml just right. At least it seemed a bit picky to me... Here's a shot of exactly how mine looks. Use space for indentation instead of tab. Note that I used "true" instead of "yes" after "dhcp4". Not sure if it matters, but I saw "true" was used on the wiki link you provided.

You OP could have mentioned that you use Linux in your original post.

I gave instructions to my shop not to upgrade the BIOS of my new NUC because of this issue. Now I'll have to undo that (Windows user here).
