I purchased a WAP54G in the US last year, which I've extensively used there and it works fine. However, here in the Netherlands I can't get it to work. I have a 220V --> 12V adapter, but when I plug it in the Power (red) and Act (yellow) LEDs light up for several seconds but then gradually fade out. It can't be a 50/60 Hz issue, because it runs on DC -- or could it? What else could it be? I am most perplexed.
