Description Edmund Laugasson 2017-07-17 00:22:09 UTC

Using Intel 8260 (rev 3a) controller
Installed amd64 kernel from http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.12.2/

When loading iwlwifi module, kernel claims that firmware modules iwlwifi-8000C-{22..30}.ucode are missing. When to look at firmware folder /lib/modules/4.12.2-041202-generic/kernel/drivers/net/wireless/intel/iwlwifi then really these files are missing.

Also log says that:
minimum version required: iwlwifi-8000C-22
maximum version supported: iwlwifi-8000C-30

Found some modules from:
https://github.com/NetBit73/NeteXt73_pakiety/tree/master/iwlwifi
https://git.kernel.org/pub/scm/linux/kernel/git/iwlwifi/linux-firmware.git/plain/

Downloaded, added to /lib/modules/4.12.2-041202-generic/kernel/drivers/net/wireless/intel/iwlwifi folder and reloaded iwlwifi module (sudo modprobe -r iwlwifi && sudo modprobe iwlwifi) and it works for now, seems to be stable so far.

When loading iwlwifi with manually added modules, log says:
loaded firmware version 27.455470.0 op_mode iwlmvm
Detected Intel(R) Dual Band Wireless AC 8260, REV=0x208
etc - see included files

Comment 8 Emmanuel Grumbach 2017-07-17 05:17:35 UTC

This bug is not relevant for this bugzilla.

Intel has released all the firmware files you need and pushed them upstream.
Ubuntu hasn't integrated them to their distribution, there is nothing we can do about this.
You can open a ticket on Ubuntu on link it to this issue if you want.

I am closing this.

Well I got response that this firmware did not work properly and they had to remove it - https://lists.ubuntu.com/archives/kernel-team/2017-July/085667.html
