Yes I guess my question is can I be sure it is trash because all the lights are still on
Before doing anything rash like throwing it away, I would check the AC adaptor. Just put your hand on it to see if it is getting overly warm while plugged in. It shouldn't be very warm at all. I'm assuming you should be able to get one of those from D-Link if it is in fact the adaptor. It ought to be cheaper as well.

My gosh, I hope mine lasts longer than a year.
