Getting 3am notifications for auto reboots on modems etc is far better then a 7am "Our internet is not working" phone calls from clients.
One of my clients for some random reason that I cannot pin down loses internet access every morning. I have replaced the modem and router, neither fixed it.
So I set the Wattbox to reboot the modem and router every day at 4am. No more phone calls about outages.
I am a trained professional..... Do not attempt this stunt at home.
