What I have different from all other cases is that I have nothing on dmesg.

# dmesg |grep iwlwifi | wc -l

  • I have dual boot with Windows 10.
  • Windows "Fast Startup" is disabled.
  • Secure boot is disabled (I have it enabled when install the linux, but disable to fix nvidia).
  • Ubuntu 21 "Ubuntu 21.04.
  • The classic "Ubuntu Drivers" only offer drivers for NVidia

# apt info linux-firmware | grep Version
Version: 1.197.3

In launchpad it say that device [8086:2725] Subsystem [8086:4020] was added to linux-firmware 1.187.7. But lspic say mine is [1a56:1673], that I can not find anything in internet.

Edit:

This is what windows see, it come installed on from factory.

Trying to enable iwlwifi, still no logs:

# lsmod | grep iwlwifi
<emtpy>

modinfo iwlwifi | grep -i version


srcversion:     C4766991DE91166408C39CE
vermagic:       5.11.0-34-generic SMP mod_unload modversions


modprobe iwlwifi


<empty>


dmesg | grep -i iwl


<empty>

Edit 3

I enable panic mode and clone git://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git and copy into my /lib/firmware. Everything is the same with exception of

# lsmod | grep iwlwifi
iwlwifi               380928  0
cfg80211              892928  1 iwlwifi

  • Fast Boot is a UEFI feature; Fast Startup is a Windows feature and the one you should disable. – ChanganAuto Sep 18 '21 at 13:13
  • It looks like the driver for the wifi device did not load. Try powering the machine off and booting directly into linux without booting windows in between. Make sure you have installed the firmware for the wifi card. Find the name of the driver and try manually loading it with modprobe and look for errors in system messages (via /var/log/syslog or dmesg). – user10489 Sep 18 '21 at 13:15
  • @ChanganAuto sorry, I am talking about "Fast Startup" on window. I follow the guide using adm power and uncheck the feature. – Sisso Sep 18 '21 at 16:20
  • @user10489 I boot everyday directly on linux. I only login on windows few times trying to fix this.

    Both dmesg and syslog are empty by "grep -i iwl".

    Searching for the "8086:2725", the launchpad 1902848. It say that device was added on linux-firmware on version 1.187.7. Mine is 1.197.3. But, they say "Subsystem [8086:4020]". Where my lspci say "Subsystem: Rivet Networks Device [1a56:1673]", 1a56:1673 is non existent in internet :/

  • @Sisso that's because it's a subsystem of the Wi-Fi card. Your card is an Intel Corporation Wi-Fi 6 AX210/AX211/AX411. – galexite Sep 18 '21 at 17:20
  • There's a few cards that windows initializes in ways linux can't undo, which is why I suggested the power cycle -- but likely this is not one of them anyway. Do you know the module name for the driver this card needs? I didn't find it in a quick search. – user10489 Sep 18 '21 at 19:17
  • @user10489 I don't know what drivers. Honestly I barely know how to find it. I normally search for Ids and find enough information. This one is a bit differently. – Sisso Sep 18 '21 at 19:38
  • I'm not finding any information on this device, it is possible it isn't supported yet. It looks like it should be supported by the iwlwifi driver. If you run lsmod | grep iwlwifi is it loaded? If not, do you get any system messages from modprobe iwlwifi ? Can you give us the version number from modinfo iwlwifi ? And check https://www.intel.com/content/www/us/en/support/articles/000005511/wireless.html and see if your card is listed and if you already have the correct firmware. – user10489 Sep 18 '21 at 20:02
  • Intel's main support page for this is https://wireless.wiki.kernel.org/en/users/drivers/iwlwifi – user10489 Sep 18 '21 at 20:03
  • @user10489 added the lsmod commands you asked. – Sisso Sep 18 '21 at 22:31
  • About search driver. What botter me is why I don't find any from ID. And why the name on lspic don't match wtih windows. – Sisso Sep 18 '21 at 22:37
  • grep dmesg isn't gonna give you anything. Do a tail -f /var/log/syslog and then do modprobe iwlwifi and give us everything that came out of the tail in between. There's some reason the module isn't loading -- either it doesn't recognize the card or it isn't finding the firmware or some other error. – user10489 Sep 18 '21 at 23:53
  • It's at least helpful to be sure the module isn't loading (not in lsmod), and I'll have to backtrack the version and see when (if?) your card was added. – user10489 Sep 18 '21 at 23:55
  • @user10489 I try to add head of linux firmaware git and reboot. I have something in lsmod, but all others are the same. After this, I try again modprob tailing the syslog, still nothing, not a single line.

    Any chance that this driver could have being installed with secure boot on, and now that I have it disable fail? Odd.. but...never knows.

  • I don't have one of these devices, and when I modprobe iwlwifi I get 3 lines, none of which includes "iwlwifi" in them. If you are getting "nothing", either you are missing an error or you are missing the lines where it loads. – user10489 Sep 19 '21 at 12:14
  • Check /etc/modprobe.d/blacklist... files.
  • ... grep iwlwifi showing no lines is not a sign of problems. I get the same (and I also use iwlwifi).
  • Even if old, https://askubuntu.com/a/1052413/226614 ... check for firmware. Also https://www.dell.com/support/kbdoc/es-ar/000144425/killer-wireless-firmware-update-guide-for-ubuntu-systems and https://forum.garudalinux.org/t/intel-ax210-wifi-not-working-after-installation/7900/11
  • Your kernel version should suffice, https://askubuntu.com/questions/1301607/wifi-intel-ax210ngw-is-not-recognized
