Intel 6 AX 200 Wifi not working in Manjaro KDE after first restart

Hi everyone.
I installed Manjaro KDE a couple of hours ago and everything works perfectly… except for the wifi.
After my first boot I was able to select my network and connect to it. But since trying out to boot back into Windows 11 it doesn’t work anymore. I have secure boot disabled for that and have no issues with my wireless connection in windows.

According to:
inxi -Nazy
I get:

  Device-1: Intel Wi-Fi 6 AX200 driver: iwlwifi v: kernel pcie: gen: 2
    speed: 5 GT/s lanes: 1 bus-ID: 02:00.0 chip-ID: 8086:2723 class-ID: 0280

so the device seems to be correctly connected. Also, Bluetooth works flawlessly.

I tried updating everything and installing the headers for my kernel, but no luck there.

If anyone has any ideas on what to do next, it would be highly appreciated. Please simply ask me for any extra information you might need.

can you add another kernel ,
linux 5.15 lts
and reboot

sudo mhwd-kernel -i linux515 

see this for seeing menu grub

Did you also disable fastboot in UEFI?

Thanks so much for the quick answers
I’m already using 5.15
And I did disable fastboot right at the start

In Windows or UEFI? You need to disable it in Windows.
Windows doesn’t shut down properly but uses some kind of hibernation and doesn’t release the wifi device.

Thanks a lot, that did it. I only disabled it in UEFI :man_facepalming:t3:
