A fresh install of ubuntu 20.04.3 in a Razor Blade Pro 17 laptop, the wifi card never showed up.

uname -a outputs

 Linux Razor 5.11.0-41-generic #45~20.04.1-Ubuntu SMP Wed Nov 10 10:20:10 UTC 2021 x86_64 x86_64 x86_64 GNU/Linux

dmesg | grep iwlwifi outputs:

[    2.333506] iwlwifi 0000:3e:00.0: api flags index 2 larger than supported by driver <br>
[    2.333519] iwlwifi 0000:3e:00.0: TLV_FW_FSEQ_VERSION: FSEQ Version: 89.3.35.22 <br>
[    2.333790] iwlwifi 0000:3e:00.0: loaded firmware version 59.601f3a66.0 cc-a0-59.ucode op_mode iwlmvm <br>
[    2.607066] iwlwifi 0000:3e:00.0: Detected Intel(R) Wi-Fi 6 AX200 160MHz, REV=0x340

I also tried this Intel article without success...

After that, I tried Intel support, but they sent me here because it's not a firmware problem but a driver problem, and drivers are provided by Ubuntu...

There it is

[    2.498488] iwlwifi 0000:3e:00.0: api flags index 2 larger than supported by driver<br>
[    2.498504] iwlwifi 0000:3e:00.0: TLV_FW_FSEQ_VERSION: FSEQ Version: 89.3.35.22<br>
[    2.498780] iwlwifi 0000:3e:00.0: loaded firmware version 59.601f3a66.0 cc-a0-59.ucode op_mode iwlmvm<br>
[    2.678275] iwlwifi 0000:3e:00.0: Detected Intel(R) Wi-Fi 6 AX200 160MHz, REV=0x340

Same results!

It seems that I've already the last driver or it doesn't want to replace the old ones?!?

I updated to the latest kernel

wget http://mirrors.kernel.org/ubuntu/pool/main/l/linux-firmware/linux-firmware_1.187.23_all.deb

The problem persists.

As of 2022-01-18, the problem still on event if I update to the last kernel wget http://mirrors.kernel.org/ubuntu/pool/main/l/linux-firmware/linux-firmware_1.187.23_all.deb

Any clue now?

I suspect that a valuable clue is:

api flags index 2 larger than supported by driver

The firmware loads but doesn't activate the device; that is, no wireless interface such as wlp3s0 is created and Network Manager is not prompted to connect.

We see that firmware version -59 is loaded.

loaded firmware version 59.601f3a66.0 cc-a0-59.ucode op_mode iwlmvm

Newer firmware files are present in the focal-updates, appropriate for Ubuntu 20.04, version of linux-firmware.

Please do:

wget http://mirrors.kernel.org/ubuntu/pool/main/l/linux-firmware/linux-firmware_1.187.23_all.deb
sudo dpkg -i linux*.deb

Reboot and check the message log:

sudo dmesg | grep iwl

Is there any improvement?
