I work at home and fast, reliable internet access is important.
Create a seamless mesh network across multiple access points.
My Apple Airport Extreme (discontinued) couldn’t reach all the way across my house.
I use Google
188.8.131.52 for DNS currently.
I used Cloudflare’s
184.108.40.206 DNS for years because it was private and not feeding advertising algorithms, but in July 2020 frustrating 10s lookups caused me to switch back to Google.
I stopped using my ISP’s DNS long ago because it takes for ever for DNS propogations to clear their caches.
