Intel Wifi Card AX200 not showing up, but Bluetooth works

Hi,

so I have a very strange issue here with my Wifi card in a dual boot setup with 2 separate Arch Linux installs on the same machine, but on differend NVMEs.
One Arch can use the Intel Wifi Card without issues, it is there after login and can connect to my AP immediately. Bluetooth is on and can connect to any devices. All well and good.
The second Arch on a differend drive does not see any wifi device at all and Bluetooth is disabled at startup (rfkill softlocked but can be unlocked by pressing the FN + Wifi key or rfkill unblock)
It seems that the OS knows there is an intel wifi card in there, since it is being listed in lspci, but it can't figure out that there is an actual wifi device that can be enabled.

lspci

06:00.0 Network controller: Intel Corporation Wi-Fi 6 AX200 (rev 1a)

dmesg | grep wifi

Installed linux-firmware package

core/linux-firmware 20230117.7e4f0ed-1

I have nothing in /etc/modprobe.d/ so no blacklisting is at play here afaik.
I have never used Windows with this machine, so I guess it's also not FastBoot related (would be an issue for the other Arch instance as well I think).
Since the other Arch instance is having no issues using the device, I think it has something to do with configuration, but I can't figure out where else to look for a pitfall. Since dmesg isn't even showing the wifi device registering, I thought it might have been some udev rule, but /etc/udev/rules.d/ is also empty.
I would be happy for any tip on where to search next.

Kind regards

Re: Intel Wifi Card AX200 not showing up, but Bluetooth works

Funny enough, I just had this issue today and have an AX200. I have Arch and Windows on separate nvme. Arch is my primary system, but I occasionally need a Windows machine. I used Windows today for a couple of things and used the wifi, but I am usually always hard-lined. I went back to Arch, and the wifi adapter disappeared like yours. I tried a reboot and shutdown. The only thing that worked was shutting down the system, unplugging the power supply, flipping the switch for good measure, and reconnecting everything. After that, everything went back to normal.

3rd link below. Mandatory.
Disable it (it's NOT the BIOS setting!) and reboot windows and linux twice for voodo reasons.
