You have been subscribed to a public bug:

Wifi hotekey (including LED lighting on/off) is broken on UX302LG with
default acpi settings.

*SOME* of the other hotkeys work :
- keyboard dim
- sound control 
- touchpad toggle.
- sleep hotkey 

not tested : external display hotkey.

Screen dim key does not work (probably due to Bug #1265544) but I'll
post a separate bug report for this (no known workaround).

WORKAROUND : using acpi_osi="!Windows 2012" as launch parameter, makes the key work correctly.
CAVEAT : Not in sync with the "soft" controls : when using the UI to switch on/off the wifi & BT, the LED stays ON on the keyboard resulting in a desynchronization between the wifi state and the keyboard LED. This is probably normal behaviour ?
