EasyOS Kirkstone v 5.2.3 - wifi not working - [solved]

[stuff79]

I uses Acer Aspire 5 labtop. The wifi hardware is "Intel WiFi 6 AX201 160 MHz". The EasyOS Kirkstone v 5.2.3 does not work with that.
---------- Some analysis output as belows: -------------------

1) Though my laptop dual boots with Windows 11, I have already disabled thw Windows Fast Boot.
2) dmesg | grep iwl , gives :

=> there is problem "no suitable firmware found!", but I don't know how to solve it.

Be grateful if anyone can help?

Missing firmware - but you knew that already.
It looks like the answer may be here: https://www.intel.com/content/www/us/en ... eless.html
It is too large for me to upload to the forum, even the indvidual blobs.

Download the second one in the list (Intel® Wi-Fi 6 AX201 160MHz).
Extract the contents and copy them to /lib/firmware
Reboot to make sure they get loaded.
Hopefully that will work.

EasyOS does not have the firmware for my own iwlwifi card (different model) but I knicked it from FatDog and it works fine.
Good luck.

If that doesn't work you may need to download the whole firmware package. However there is not one matching the list in the current package, but I found one (iwlwifi-so-a0-hr-b0-64.ucode)in this slightly older version: https://git.kernel.org/pub/scm/linux/ke ... 815.tar.gz

Thanks a lot.
It works.
By the way, my typo error : the version I installed is 5.3, not 5.2.3
