2cents FWIW.....Another of a hundred ways....
I also use a radio internet provider. They can be flaky. Nothing else where I am at and I don't trust them.
I use pihole as an dns server for my network.
TL;DR
It has the option of using unbound as it's upstream server or any other DNS server you like. It caches your DNS requests so they (computers) are not constantly looking out in the I-net.
It can be set to serve DHCP for the network all the while blocking ad sites like google anaylitics, etc. setting itself as the dns provider. Right now I have 102K different ad sites it blocks from it's own list. Simple to set up.
You would be surprised at the amount of blank spots that used to be ads on a webpage. Or rather you would be surprised at the amount of ads you would see when you are somewhere else not blocking ads.
My setup = radio modem > opensense firewall > Pihole > Open-WRT router > LAN
