I just came home for winter break and attempted to plug in a linksys WRT54G router I was using before I left. So I plugged the power adapter in and the router started crackling and I unplugged it and could smell smoke. 8O SO...what just happened? Did I happen to pick the wrong power adapter? It looks like the same one I used before, and is my router completely dead now, and I just have to buy a new one? Thanks.
