After google, https://www.intel.com/content/www/us/en ... rking.html

probably in the future you´ll find a driver. CentOS comes with good support for server hardware...

if you want to use it as a desktop now, buy a 15 buckazoids simple usb adapter or upgrade your kernel

I would suggest checking ELRepo to see if they have a kmod package for it. If they don't then they have a bug tracker you can raise an RFE on to request it.

It might also get added to the RHEL kernel at some point but in 8.0 it doesn't seem to be there.

CentOS 5 has been EOL for nearly 3 years and should no longer be used for anything!

Reply from ELRepo (https://elrepo.org/bugs/view.php?id=961)
The kmod-redhat-iwlwifi package that has just been released today from Red Hat (kmod-redhat-iwlwifi-4.18.0_107_dup8.0-5.el8_0.x86_64.rpm) has the ID pairing of your device.

I suppose CentOS will rebuild and publish it soon. Or else, you can install the kernel from CentOS Stream (4.18.0-144.el8 or 4.18.0-147.6.el8) which has the same support.
Does CentOS has a plan to rebuild and publish it.

Hi
I have installed that and can confirm it works well
But did you experience a battery drain
I have RHEL8 installed on precision 7540 and the battery just drains fast
Powertop reports minimal of 22w power consumption at blank desktop and goes to 30w with just firefox opening

Did you use tuned-adm to set the powersave profile?

Yes I have tried that
It did not help really much

rhel 8.1 supports the wifi card out of box without the need of kmod

I believe that CentOS built and shipped kmod-redhat-iwlwifi recently that should support those cards on 8.0 while CentOS 8.1 is in progress.
