OpenWrt is a great router firmware with lots of features, flexibility and security updates. It is basically a small Linux distribution and does a smart job at adding enhancements to any “supported” router. One can read more about it here.

I have been using Google Wifi for a while now and it has been a great experience. It has an amazing HW (4GB of storage and 512MB of RAM). Google SW can be controlled using Google Home but privacy, DNS, parental controls, firewall, ad-blocking and other features are either not supported or are not as good as I would like them to be. And also my version of the Wifi AC-1304 does not receive any new features.
