I used to run an ASUS GT-AC2900 router on my Frontier fiber without issue. I eventually loaded it with Asuswrt-Merlin firmware to get more functionality out of it such as ad blocking and IP blocking and that worked pretty well. But, it was pretty easy to overload it with too many feature if you were not careful with what you enabled with that particullar router. The newer ASUS routers could handle all that now I'm sure.

I have since moved to a NanoPi R4S running OpenWRT. It's a 6 core ARM CPU so you can do what ever you want with it. I like that I am all modular now. R4S is the router which connects to a switch, which has two wireless access points connected to it. So now I can upgrade my wifi without having to replace my router and vice versa.

If you are technically inclined I would recommend running a device with OpenWRT as your router. They now have an official OpenWRT router that is ready out of the box.
