Power On wifi issue on NUC7i3BNH with Multiple different Linux OSs

I have a Ubuntu Forum post: https://ubuntuforums.org/showthread.php?t=2414499&

 

I have found a very odd issue that when I turn on my NUC from a Powered Off state (Plugged in but shutdown/off) where the wifi chipset (Intel 8265) is not see on boot. If I log into my account then do a reboot the wifi works fine. This is very frustrating. I have been working with the Ubuntu forum for a couple of days now, but I wanted to see if there was help from anyone over here.

 

Things I have done

  1. Tested with Ubuntu 18.04, Ubuntu 18.10, Fedora 29 - similar results on all. There are a lot of notes in the Ubuntu case.
  2. Reset BIOS settings - did not fix it - Fast Boot is off FYI
  3. Checked for newer releases of BIOS - I am on 76 which is the most recent

Because this is happening on multiple OS versions and different platform (Debian vs RHEL) types I believe this is a BIOS issue.

If anyone has ideas of what other things to try please let me know.

Hello PPeas, Thank you for posting on this Community. These operating systems have not been validated for Intel® NUC products. However, we would like to gather more information to troubleshoot this issue in case it can be fixed through BIOS. 1. Does "Powered Off state (Plugged in but shutdown/off)" mean stay off after power failure? > BIOS > Power > Secondary Power Settings. 2. Is WLAN enabled in BIOS? Wanner G.

Powered off means plugged into an outlet but not turned on.

WLAN is enabled in BIOS or I would not ever see wifi but I do after a reboot.

Hello PPeas, I am writing to let you know that we were unable to replicate this issue. We tried both a wireless and a wired connection. We installed UBUNTU* 18.04 in one of our units. In this scenario, we would like to know if you could replicate this behavior one more time and attach a picture showing that the wireless or wired connection is down (e.g. ip-br a) Wanner G.

Here I reinstalled Kubuntu 18.04 to my NVMe during the install the Wifi is seen. I rebooted the system and wifi is still good. See this picture belowIMG_20190320_162636.jpg

 

I then did 'sudo shutdown now' waited 15 to 20 seconds and powered my NUC back on. The wifi doesn't just not connect. there is no device in lspci and there is no adaptor. All of this information is very much detailed in the Ubuntu Forum case I put in my 1st note. See the picture here

and just for fun, here is a picture of my current BIOS version which I believe is still the latest for this model of NUCIMG_20190320_163036.jpg

 

My next thought is to do a BIOS downgrade, but I am not sure I want to do that yet. Please let me know what is found.

Hello PPeas, Thank you for the update. The latest BIOS firmware available for Intel® NUC Kit NUC7i3BNH is Version: 0076. There is not really a fix included these types of connectivity issues, but you may also install it. v. 0076 https://downloadcenter.intel.com/download/28640/BIOS-Update-BNKBL357-86A-?product=95066 We have not been able to replicate this issue. We shut down the unit using the Graphical User Interface and the command line. 1. This behavior could be caused by a hardware failure. To address it, we recommend contacting Intel Customer Support in your region for warranty options. Intel Customer Support Contact Information for US and Canada https://www.intel.com/content/www/us/en/support/contact-support.html#@11 Intel Customer Support Contact Information for Europe, Middle East and Africa https://www.intel.com/content/www/us/en/support/contact-support/emea-contact.html Intel Customer Support Contact Information for Asia-Pacific https://www.intel.com/content/www/us/en/support/contact-support/apac-contact.html Intel Customer Support Contact Information for Latin America https://www.intel.la/content/www/xl/es/support/contact-support/lar-contact.html 2. This could also be caused by your system configuration although it happens while using different distributions. 3. If you would like to replace the unit, and the issue persists, then we recommend continue working with your distro's support channels to find out if there are any known connectivity issues that can be addressed with a driver reinstallation or update.
