Could not to use Intel Corporation Wireless-AC 8265 on Jetson device

[dandelion1124]

I tried to use use Intel Corporation Wireless-AC 8265 on Jetson device.

Jetson Linux 36.2(https://developer.nvidia.com/embedded/jetson-linux-r362) is based on Ubuntu 22.04.

$ lsb_release -a
No LSB modules are available.
Distributor ID:	Ubuntu
Description:	Ubuntu 22.04.3 LTS
Release:	22.04
Codename:	jammy

$ uname -a
Linux jetson-orin-nx01 5.15.122-tegra #1 SMP PREEMPT Thu Nov 30 10:30:37 PST 2023 aarch64 aarch64 aarch64 GNU/Linux

But, Wireless LAN does not work on this environment.

I checked "sudo lspci -vvv". It seems that system could recognize Wi-Fi module as PCIe device.

. But, system failed to load iwlwifi module.

$ modinfo iwlwifi
modinfo: ERROR: Module iwlwifi not found.

$ sudo modprobe iwlfifi
modprobe: FATAL: Module iwlfifi not found in directory /lib/modules/5.15.122-tegra

On the other hands, there is firmware in "/lib/firmware". Please give me advice.

$ ls /lib/firmware/iwlwifi-8265*
/lib/firmware/iwlwifi-8265-21.ucode  /lib/firmware/iwlwifi-8265-27.ucode  /lib/firmware/iwlwifi-8265-34.ucode

Hello, @dandelion1124  

Thank you for posting on the Intel® communities.  

I understand that you are having issues using the wireless card, I will do my best to assist you. 

• Is the Intel® Dual Band Wireless-AC 8265 the pre-installed Wi-Fi card in your system or is it an integration (upgrade/ not the original card)? 
• What is the specific model of your system? 
• Was it working fine before? 

Best regards,

> What is the specific model of your system? 

I used reComputer J4012.

> Is the Intel® Dual Band Wireless-AC 8265 the pre-installed Wi-Fi card in your system or is it an integration (upgrade/ not the original card)? 

"reComputer J4012" does not have wireless LAN module.

So, I have integrated Wi-Fi module(Intel Dual Band Wireless-AC 8265) to this board.

> Was it working fine before?

Yes. In previous version(Jetson Linux 35.4.1 https://developer.nvidia.com/embedded/jetson-linux-r3541), Wi-Fi module worked fine.

This OS is based on Ubuntu 20.04.

I have additional information. I downloaded backports-5.15.81-1.tar.xz from the following page. 

https://backports.wiki.kernel.org/index.php/Releases

And, I built iwlwifi module from this source. As a result, Wi-Fi module worked fine on Jetson Linux 36.2.
