Auto reboot or 3rd party firmware

I've other thing to note, my connection is a 300 mbps down / 40 Mbps up connection. No extra equipment (just the Orbi of the cable modem). No kids streaming, and even with that said, it's only the wife and I streaming together on a single device. The issue happens too frequently to be sure device updating (there are literally 5 devices, of which one is a laptop, 2 phones, and 2 roku's).
