The internet doesn't go down. (Knowing this will boost your tech savvy creds! ) However, your ISP's connection might drop, or your ISP's gateway may need to be rebooted. Does your internet connection go down often? If yes, then get a new ISP, or call them and tell them what is happening. Most ISPs can fix most issues remotely. If your gateway is more than 5 years old, ask for a new one. One of the top reasons for having Home Automation is to be able to control and monitor your home while you are away. If your internet connection is going down all the time, then your internet connection is the first thing to fix. I cannot even remember the last time my ISP (AT&T GigaPower) lost its internet connection. I do reboot the gateway about once a month (whether it needs it or not). I only use Wi-Fi, Echo, and a smartphone. I don't need a hub, nor does anyone.
