In 12.04, this function key didn't work. In fact, it wasn't even recognized as a keypress (details on my old post here).

After upgrading to 14.04, it works. Great!

Only problem is that this key also has an indicator light. It toggles, but is out of sync with the state of wifi (i.e. if wifi is on, the light is out, if wifi is off, the light is on).

Can I change this somehow?
