WiFi card not showing up

I'm on an HP laptop (AMD) and my Wi-Fi isn't showing up. It used to work fine before I tried deleting network manager to switch to netctl (network manager was buggy such that it randomly stops working until I reboot), now I can't see any WiFi networks when I run `lspci` or `ip link`. Bluetooth still works (Realtek `0bda:b85c` on USB idk if this is important I'll just leave it here just in case).

I've tried disabling `netctl` and re-enabling NetworkManager, installing Realtek drivers from AUR, updating firmware, checking the BIOS to see if my wifi was disabled (it's not), checking `rfkill`, power cycling—nothing worked. Ethernet is fine, but the Wi-Fi is just gone. Any ideas on how to fix this I've been at it for hours now. Sry if this que is stupid, I'm still new nd idk what to do.

Re: WiFi card not showing up

The device presence (esp. in lspci!) doesn't hinge on some userspace network dameon.

lspci -nn
lsusb -tv
uname -a
pacman -Qs kernel

Is there a parallel windows installation?
=> 3rd link below. Mandatory.
Disable it (it's NOT the BIOS setting!) and reboot windows and linux twice for voodo reasons.

Edit, also

rfkill
