Pihole not blocking any/very few ads.

[jfb]

You have several choices:

1. Use Pi-Hole as your DHCP server, and turn off the DHCP on the router (not all routers support this option):

How do I use Pi-hole's built in DHCP server (and why would I want to)?

Using Your Existing Router For Network-wide Ad Blocking You might not need to use Pi-hole's DHCP server: In many home environments, your router also functions as your DHCP server. In this case, you can often set Pi-hole to be the DNS server for your network clients in the router's DHCP (or LAN) settings page, which allows all of your network clients to block ads simply by connecting to the network. Setting it up this way is also what makes Pi-hole very powerful for network-wide ad blocking. …

2. Manually map clients to Pi-Hole (you can't do this on some clients like IOT devices).

3. Figure out the settings on your router, or even put your current router in bridge mode and put a different router on the network to run NAT and DHCP services.
