So I recently purchased an Airport Extreme to replace my POS Linksys wireless router. All was fine until today, when it stopped working. I came home and the Airport was hot... really, really hot, and the internet wouldn't work. I unplugged it to cool it down, and when I turned it back on the internet still wouldn't work. The green light comes on, says it has an IP address, but nada. I tried resetting it and creating a whole new network, and still nothing. What to do?
