Intel Wi-Fi Ax201 driver

Post by bluforce » 2021/01/06 15:17:39

Do you guys have any idea how we can get a wifi driver for the Intel AX201 card installed? Our new Dell Latitudes are not recognizing the card.

Code: Select all

00:14.3 Network controller: Intel Corporation Wi-Fi 6 AX201
        Subsystem: Intel Corporation Device 4070
        Flags: bus master, fast devsel, latency 0, IRQ 16

Your output shows:

Code: Select all

Kernel driver in use: iwlwifi
The changelog for the kernel has:

Code: Select all

* Mon Sep 16 2019 Jan Stancek <jstancek@redhat.com> [3.10.0-1093.el7]
...
- [wireless] Backport iwlwifi driver from linux-5.3-rc5 (Stanislaw Gruszka) [1641110 1641098 1641096 1640935]
...
And finally, Intel says that official kernels 5.2+ support the AX201.

Thanks for the reply.
I'm not sure what I am doing wrong then. I can't enable wifi. CentOS says no wifi adapter found. Any idea how to enable?
Thanks

Is NetworkManager-wifi installed?

Looks like it is:

Code: Select all

$ yum install NetworkManager-wifi.x86_64
Loaded plugins: fastestmirror, langpacks
Loading mirror speeds from cached hostfile
 * elrepo: iad.mirror.rackspace.com
Package 1:NetworkManager-wifi-1.18.8-2.el7_9.x86_64 already installed and latest version

I double checked the BIOS settings and the wifi card is enabled.

I booted up to the CentOS 7 install disc as a test, selected "network and host name". It actually sees the wireless card, but when you try to flip it ON, it goes right back to OFF.
It says: Wireless (wlo1) Intel Corporation Wi-Fi 6 AX201 - Unavailable. "Configure" button is greyed out as well.

Code: Select all

You could try one of the elrepo kernels. If it works with them, RH messed up their backport.

I was able to get the wifi working with the elrepo kernel. However, we cannot use VMWare Workstation 16 with this kernel. We contacted VMWare and they do not support anything but the default kernel. Do you all know anything else we can try to get the 3.10.0-1160.11.1.el7.x86_64 kernel to see the wifi?

It looks like CentOS sees it according to /var/log/messages

But the settings still show "no wifi adapter found"

Thanks for any input!
