wireless - Can't unblock rfkill internal wifi, but usb wifi doesn't work either

Sometimes the internal wifi on my Amilo Pi 2515 is disabled and can't be enabled using the hardware switch (in BIOS too), since the device is a bit dated and this only occurred recently, I'm assuming a hardware issue.

So I tried using a USB wifi dongle instead, but that gets disabled too.

rfkill unblock all does not change anything.

Is there some way to ignore rfkill altogether?
