CentOS

Hi,
I am fairly new to centos and recently upgraded my motherboard to an MSI pro carbon wifi motherboard which has an ax200 intel wifi 6 modem. Now centos does not detect the wifi hardware and thus I can't use the wifi. Using lspci command returns "intel corporation device 2723 (rev 1a)" for network controller. My centos is fully up to date (kernel 3.10.x) but I found that official support for ax200 is only included with the linux kernel 5.1 or later. Is there any way I can make the wifi modem work with centos? Either through manual installation or updated drivers? Help is much appreciated and thank you in advance.

Most likely solution I can think of is to use a replacement kernel like kernel-ml from ELRepo. The copy of iwlwifi in kernel-ml 5.2.5 says it supports 8086:2723. It might also be added to the CentOS 7 distro kernel, maybe at 7.7 which should be along in the next month or two at which point you may be able to flip back to the distro kernel.

Sorry for responding so late; I updated my kernel to kernel-ml 5.2.9 (also updated my Nvidia drivers to have a working gui) but in the settings it still tells me "no Wi-Fi adapter Found / Make sure you have a Wi-Fi adapter plugged and turned on". Did I miss something or do I still have to enable a setting?

(Not sure if it was the case before updating my kernel, but it seems that my bluetooth is now working (which is integrated in ax200 I think). Not sure if that fact can help))

Just to give a bit more info:

This iis what I get when running:

Everything is working now!

After updating to the new kernel I also had to add the ax200 device firmware, which can be found here: https://www.intel.ca/content/www/ca/en/ ... rking.html

I followed the readme instructions and placed the iwlwifi-cc-a0-46.ucode in /lib/firmware. After rebooting the wifi adapter was recognized and I could connect to my router

Hello!
I'm taking the liberty of bringing up the subject again because I have the same concerns.
My intel ax200 wifi card doesn't work.
I followed all the previous step in the topic, but still doesn't work.
If you could help me, that would be wonderful.
Here my previous step:
- Update kernel : - download firmware iwlwifi-cc-46.3cfab8da.0.tgz from https://www.intel.ca/content/www/ca/en/ ... rking.html
- copy iwlwifi-cc-a0-46.ucode in /lib/firmware folder
- active firware with : - reboot

and no wifi

Thanks for your help!


lastly the harware status:

Hey!
Finally my wifi card works!
The main issue is that a double window boot, and windows was in fast startup mode which block the firmware upload.
So I fixed the issue by disable the fast startup and done all the previous steps.
