How’s the router working for you?
I eventually purchased two routers, a Netgear and an ASUS router. The Netgear, while older, works better than the ASUS router on the Comcast connection. I think that's because Comcast, at least in this region, interfaces better with it. I still have the ASUS router, and I may use that in the future when/if I make the switch to the fiber optic provider out here so I can run both side by side and see this one works the best, but so far I'm sticking with the Netgear router.
I also had to upgrade my cable modem because my old one was a DOCSYS 3.0 modem, and Comcast would no longer support it. So I had to upgrade to a DOCSYS 3.1 modem, another Netgear product.
