Why are these numbers in Russian? Tell me a joke!

You want 3 features, and then you can decide which product(s) satisfy them:

1. A router

2. A wireless access point (often included with the router for consumer stuff)

3. A DNS server that can block ads.

A good cheap set of options that would set you up to play and grow would be:

1. UBNT ERX for $60: https://store.ui.com/us/en/products/er-x

2. A UBNT Wifi 6 lite AP $100 https://store.ui.com/us/en/products/u6-lite

3. A pihole (if you have a Microcenter nearby you can grab a Pi 3 for like $25, if you want a case it’s probably $10 more).

You can run the pi-hole software on a lot of other things too https://docs.pi-hole.net/main/prerequisites/.
