My WiFi keeps shutting down periodically throughout the day. I get notified my cameras go offline while I'm at work then I can't stream when I get home until I unplug the modem and router. Once I do that, it works for the rest of the night. Spectrum said they think it's from the router and not on their end. We bought this router about 2 years ago. Would the router be going bad that soon? Any advice or tips? Thanks!
