Ubuntu 20.04 not recognizing Intel Wi-Fi 6 AX200

Howdy,

New PC build: TR 3960X with a GB TRX40 Aorus Xtreme mb.

I’ve got both Windows 10 and Ubuntu 20.04 installed. I noticed that linux isn’t working properly with the built in Intel Wi-Fi 6 AX200: no wifi options are presented, although it is interesting to note that bluetooth seems ok.

  • Linux 5.4.0-42-generic

$ lshw -c network

Any suggestions?

thanks in advance.

If you have any fast boot options, try disabling them… dual booting can be tricky with sucky firmwares of new motherboards/devices that take forever to fully initialize, and therefore they don’t really reboot fully when you think you’re rebooting.

Also, what does dmesg tell you about firmware versions being loaded?

Thanks for responding. In fact I wasn’t using fast boot.

Here is the output:

strangely – I did two things and we seem to be BACK! Wifi recognized ok now. One, I removed the antenna that was plugged in; and 2) I unplugged the ethernet that was also being used.

I wonder if there is some strange conflict with the ethernet? when I get a moment, I’ll try a few experiments to see if I can isolate what was causing the problem.

Regardless, I’m presently up and running – but will watch it.

Have you tried upgrading to a newer kernel?

5

No. I thought this might be needed. I suspect there is some odd interference when also using ethernet.

Hmmm, I know this reply will probably not help, but I am intigued as I am using the same CPU, same MB, Win10Pro and Ubuntu-Mate 20.04.1.

FWIW, my system finds all of my wifi ssid’s, and can attach to any of them successfully.

I am also attached to the two ethernet ports, and my BT is also working.

So, though I am not presenting a possible “fix” for you, I CAN confirm that it could work, and is not a general hardware/os incompatibility.

If you want any specific settings I am using, or contents of any conf files, please just ask.

Good luck,

It shouldn’t be. The ax200 got support in 5.3 iirc. Ubuntu 20.04 should be on 5.4

You can always try a newer mainline but I doubt this will fix it.
