This morning my C510W was offline even though it was still on and patrol mode was working.  Since I couldn't connect to it from the app I had to go outside and unplug it and plug it back in, then it reconnected.

I thought about setting up a daily auto-reboot time so that if it happens again it will only be offline until the next reboot time, then it will reconnect without me having to go out and unplug it.  But then I realized that if this setting is not stored on the camera itself but triggered by the app, if the camera is offline it won't reboot.  

So does anyone know if this setting is stored on the camera itself or will it not work if the camera loses its wifi connection?
