DNS server set to Pi-hole IP works for wired but not Wifi devices

[mak1]

I changed my T3200 router to static DNS for DNS Server 1 and DNS Server 2, using the IP address of my Raspberry Pi. Add blocking works for wired devices on my network but not for WiFi devices. I cannot find a setting in the router that would address this situation.

What do the WiFi devices show for DNS servers?

They list two IPv6 address, which I haven’t figured out who they are and then the two correct DNS IP addresses.

Does the Pi-hole have an IPV6 address? Maybe you need to set that on the T32000M as well as the IPV4 address.
