If I were going to be streaming all my TV services and was worried about 4K , I would upgrade to an XR500. Right now with 50/50 fiber from my ISP and a Netgear router in AP mode doing my wifi connectivity, I'm content with the R1. I don't really have a complicated home network, but I do have many wifi connected devices. I seldom think about my routers except to game. As long as everything stays that way, I'm sticking with the R1.
