I don’t think that’s necessarily true at all. I just replaced my mid-grade router at home with an enterprise level router and all 10 of my Hikvision cameras and three Wyze cams stopped dropping. Packet congestion is a real thing on routers that aren’t made to handle it. In a connected world people have more IoT devices on their LAN than ever and the same [mod edit] old routers.
