Router is answering DNS queries instead of selected DNS provider

[RamSet]

Looks like your clients are not using the Pi-hole IP as their DNS server.

You can do any of the following:

1. Setup the DNS manually on the clients to the IP of your Pi-hole (192.168.1.132)
2. If your router lets you set-up DHCP related parameters, set the Pi-hole IP as your LAN DNS.
3. Setup the same Pi-hole IP in your router as your WAN DNS.
   Also keep in mind this:

Why should Pi-hole be my only DNS server?

Reduced Ad Blocking Capability The main reason you should Pi-hole as your only DNS server is that you will see increased performance in the blocking of ads. If you have two DNS servers (Pi-hole and something else), your network clients may not always query Pi-hole for name resolution. If a query happens to be answered from a non-Pi-hole DNS server, your block lists will not apply (since that DNS server doesn't know about them). All Queries Need To Go Through Pi-hole First Since other DNS serv…

4. Disable the router's DHCP and use Pi-hole as your DHCP server.
   This is by far the easiest and cleanest method (I run it like this with over 60 clients).
