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
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.
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 below
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 NUC
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.
