Booted up my PC this morning.
Noticed WIFI does not work. 🤔

`lspci -nnk | grep -iA 3 net` lists my network controller correctly...

`rfkill list all` ONLY shows hci0: Bluetooth

Turned out that the firmware entered an undefined power state ("latching up") and rebooting won't help.

To solve this, I switched off power and had to drain the capacitors by pressing the POWER button for like 60 seconds and power state resets.

Ah, computers :)

I am mostly curious what is causing the latch up... this happened before but went away on its own. Never had this with any other computer before.

@bitbraindev do you have dual boot with windows by any chance? I faced something like this before with dual boot. If I did a regular windows shutdown, the wifi interface would remain locked and not show up on Linux. The only way I could make it come back was by booting windows again and doing a restart instead of shutdown.

@thisisvini nah, I got rid of Windows for good. Scorched off the earth!
