The soft wireless toggle LED/button is unmapped. Touching the LED is supposed to toggle the LED between orange and blue and turn the wifi on/off. The error:
[194089.737236] atkbd serio0: Unknown key released (translated set 2, code 0xf8 on isa0060/serio0).
[194089.737242] atkbd serio0: Use 'setkeycodes e078 <keycode>' to make it known.
The keycode needs to be 247 - which kills wifi and bluetooth.
