Wireless Interface not being detected [Solved]
I am running a windows desktop and trying to set up Arch linux as dual boot.
After installing Arch Linux I had Network Manager set up and connected correctly. After I installed and ran my desktop environment I lost connection and after rebooting I can no longer detect my wireless device.
#ip link
Only shows lo and Ethernet devices.
#ls /sys/class/net
Shows the same thing
#lspci -k
My device is an Intel Wi-Fi 6 AX200 with the iwlwifi driver
#dmesg | grep iwlwifi
Shows the firmware being loaded
So it looks like the driver and firmware are working properly but I still cant detect it.
Windows can still connect through the device but even when I reloaded the Live Environment it could not find the interface anymore.
I am unsure what the problem is or where I can look for a solution.
Any help would be appreciated.
Thank you

Re: Wireless Interface not being detected [Solved]
Could you show output of:
ls -al /usr/lib/modules/
uname -a?

Please also post the complete system journal.

This user tried to mitigate a Lenovo related issue w/ S3'ing during the boot, causing the chip to fail

If there's a windows installation, disable windows fast boot (link in my signature)

Re: Wireless Interface not being detected [Solved]
Sorry for the late response, the firmware crashes links you posted helped me solve the issue. I thought I had windows fastboot disabled but after removing power completely then resetting the bios it worked again. Thank you both for your help.
