I have a Belkins Play adapter -

Theres 2 L.E.D's on the adapter but only 1 lights up. I've contacted Belkin support but they tell me its fine... the thing is not only is the incorrect l.e.d on, the other doesn't light up which should. Seems a bit strange.

The L.E.D on mine that lights up is "B" according to the PDF file which is WPS/Security LED but "A" Power/Activity LED doesn't?
