since yesterday I'm facing the problem that I can't use W-LAN or Bluetooth with my Laptop device. I was running several commands from other threads (see below), but none was helping. At the end I booted the system with a different Kernel I had installed and finally the W-LAN worked again.

Today, the yesterday's issue appeared again but this time I'm unable to figure out how to get along. Any help is appreciated.

Here, the error output looks similar to the one I've got, but execution of the commands rmmod and modprobe did not help. This did not help either.

System OS: Ubuntu 20.04.3 LTS with Kernel 5.4.0-89-generic x86_64

My device's network controller: Intel Corporation Wireless-AC 9462

lspci -kvnn | sed -n '/Network/,/^$/ p' gives some more details:

Update

Following Pilot6 advice to install HWE it still does not work. However the error message is more precise this time:

uname -r outputs 5.14.14-051414-generic.

dkms status outputs:

sudo dmesg | grep iwlwifi outputs the same output as before.

Update 3

Following @unbi-rabka answer did not solve the problem.I still do not have wireless connection.

sudo dmesg | grep iwlwifi outputs:

[    3.373741] iwlwifi 0000:00:14.3: enabling device (0000 -> 0002)

Also I tried to install a brand-new installation of Ubuntu-18.04 alongside my current installation. But it did not help either.

  • Try to switch to HWE kernel. – Pilot6 Oct 25 '21 at 17:28
  • Thanks for your quick reply, can you provide me some information on what its purpose is and how to switch? – angelogro Oct 25 '21 at 17:31
  • The purpose is to switch to the 5.14 kernel. Run sudo apt install linux-generic-hwe-20.04 and reboot. It will leave the existing kernel intact, you can switch back. – Pilot6 Oct 25 '21 at 17:33
  • But it it is a dual boot with Windows, it's another issue. – Pilot6 Oct 25 '21 at 17:34
  • My only OS is Linux - does this mean, your advice won't help me? What also confuses me is that until yesterday everything worked fine for almost two years without any change being made (up to what I've noticed)... – angelogro Oct 25 '21 at 17:40

    If it is NOT a dual boot, it's worth trying. Maybe firmware got an update and it's not good for the old kernel. – Pilot6 Oct 25 '21 at 17:49
  • Edit your question and show me ls -al /lib/firmware/iwlwifi*.p*. Start comments to me with @heynnema or I'll miss them. – heynnema Oct 25 '21 at 20:02

  • Rename those two files to add .HOLD to the end of their names. Reboot. Retest. Report back. – heynnema Oct 25 '21 at 20:11
  • Also show me dkms status... and put that output into your question, not the comments please. – heynnema Oct 25 '21 at 20:13
  • Question is edited @heynnema. This comment is to make sure you noticed I have answered already... – angelogro Oct 25 '21 at 20:35
  • Did you rename the files and test yet? Which kernel are you running on right now? 5.14.14-051414-generic? – heynnema Oct 25 '21 at 20:43
  • @heynnema The files names are /lib/firmware/iwlwifi-ty-a0-gf-a0.pnvm.HOLD and /lib/firmware/iwlwifi-so-a0-gf-a0.pnvm.HOLD at the moment. I am running 5.14.14-051414-generic. – angelogro Oct 25 '21 at 20:47
  • Good. Now reboot and test wireless. – heynnema Oct 25 '21 at 20:49
  • @heynnema I rebooted. It is still not working. The error message when running sudo dmesg | grep iwlwifi is the one shown in the question. – angelogro Oct 25 '21 at 20:54
  • Download https://wireless.wiki.kernel.org/_media/en/users/drivers/iwlwifi-9000-pu-b0-jf-b0-34.618819.0.tgz, uncompress it, put the file into /lib/firmware, reboot, retest. – heynnema Oct 25 '21 at 20:58
  • Oh, here's a much never version of the firmware file... https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git/tree/iwlwifi-9000-pu-b0-jf-b0-46.ucode – heynnema Oct 25 '21 at 21:07
  • @heynnema The error remains the same. Just to be sure: there are a lot of iwlwifi*.ucode files in /lib/firmware. However the system apparently tries to load the ones starting with iwlwifi-QuZ-a0-jf-b0-[number].ucode as (as I understood it) they correspond to my device's wireless module, starting with the highest version number, which seems to be 64 and - when not finding it - looking for the next one which is 63. (see error message in the question) – angelogro Oct 25 '21 at 21:11
  • You have an Intel Corporation Wireless-AC 9462, according to your info. Did you try the newer .ucode link that I gave? – heynnema Oct 25 '21 at 21:14
  • See https://www.intel.com/content/www/us/en/support/articles/000005511/wireless.html to find the filename, and then go to https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git/tree/ to get the newest version. – heynnema Oct 25 '21 at 21:15
  • @heynnema Yes. The file is inside the folder. However the system seems to always open the file iwlwifi-QuZ-a0-jf-b0-[number].ucode which does not correspond to Wireless-AC 9462. Is the firmware file name which is loaded (e.g. using modprobe) maybe saved in some config file? Do you know how to explicitely tell the system to use this specific firmware https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git/tree/iwlwifi-9000-pu-b0-jf-b0-46.ucode? – angelogro Oct 25 '21 at 21:31
  • Have you tried backport-iwlwifi-dkms? – heynnema Oct 25 '21 at 21:49
  • @heynnema Actually I tried what is propsed in this thread https://askubuntu.com/questions/1046589/backport-for-iwlwifi but the error message remains the same. – angelogro Oct 25 '21 at 22:40
  • I'm at a loss then. Sorry. – heynnema Oct 26 '21 at 02:30
  • Wait, you say this isn't a dualboot, are you in a VM? Is this adapter directly passed to the VM or no? The VM should not have any access to the host system's hardware unless USB or PCI passthrough is done (and that'll break things if your host system is using the hardware) – Thomas Ward Oct 26 '21 at 12:55

    @ThomasWard It is not a dualboot. I am not using VM. – angelogro Oct 26 '21 at 13:01

I just had the problem recently (August 2022) after years of no problems with an Intel 3160 wlp2s0. One of the incremental upgrades to 20.04 I suspect. I solved it by upgrading to 22.04

i use kubuntu 20.04 and Wifi 6E AX210

i have same issue after update os, so i try this on my pc and its works

mv /lib/firmware/iwlwifi-ty-a0-gf-a0.pnvm /lib/firmware/iwlwifi-ty-a0-gf-a0.pnvm.bak

after rename, you must restart your pc

For anyone else arriving here looking for a solution, I've had a similar issue with a laptop on 20.04, with an Intel 9461 adapter.

It appears to me to be a kernel/driver/firmware mismatch. I was able to resolve by upgrading the linux-firmware package. To do this, I looked at this page to see the available versions of this package for 20.04 and newer releases.

I downloaded the newest, but that did not change the problem, so next I tried the next-newer than what is available on 20.04, which is from 21.04 (hirsuite) and is version 1.197. This fully resolved the problem, and should not be broken by an update, assuming any linux-firmware updates to 20.04 maintain their version scheme. Any updates to this package in the focal repository would be versioned 1.187.x > 1.187.29, which would be greater than the current version, but always lower than 1.197...

Here is a link to the mirrors page for a direct download to version 1.197 of the linux-firmware package.

EDIT: Scratch that! Looks like wpa-supplicant.service was restarted during the apt installation of 1.197, and it just happened to do so when a working firmware file was the only one present in /lib/firmware/. Subsequently, downgrading to version 1.187 is giving a working combination.

I've pinned that package to the 1.187 version and now it is actually working, even after a reboot.

This is what I did on 20.04:

user@computer:~$ cat /etc/apt/preferences.d/linux-firmware-iwlwifi-on-5-13-0-fix 
Package: linux-firmware
Pin: release a=focal-updates
Pin-Priority: -10

Package: linux-firmware
Pin: release a=focal
Pin-Priority: 1001
