I have a couple ap700 and recently one has gone out, actually the newest one I have. The leds on the side that indicate power is on and wifi connectivity are working properly. It shows that it connects to the app and is on the same program as my other one. I can control the other one no problem but this one just doesn't work anymore. Is it roasted? I can't see that both sides would go out at the same time. Also the highest setting I use is 80 percent. I would be guessing at how long I've had it but probably a minimum of 3 years old. I've gone all through the app trouble shooting and haven't found anything useful. Disconnected and reconnected multiple times. Also cut power to it several times. No luck.
