Can't change DNS server to Pi-Hole

Can't change DNS server to Pi-Hole

Can't change DNS server to Pi-Hole

Model: Archer C80  
Hardware Version: V2
Firmware Version: 1.13.15 Build 240812 Rel.53972n(4555)

Pi-Hole (6.0.6) installed on Debian 12 at 192.168.1.14 (static ip). Confirmed working with `nslookup google.com 192.168.1.14`.

 

On the Archer C80 Network > Internet > Advanced Settings page, if I select "Use the following DNS address" and enter 192.168.1.14 as Primary DNS and leave 0.0.0.0 as optional Secondary DNS, I get: "Invalid Primary DNS Server. Please enter another one."

 

Why is this happening?

 

Thanks.

Hi,

 

The settings in the menu "Advanced" -> "Network" -> "Internet" relate to the network that is connected to the router's WAN port.

 

If you have the Pi-Hole connected to your router's LAN network, then all you can do is to enter it's IP address in the "DNS" field(s) under "Advanced" -> "Network" -> "DHCP Server".
Client devices on the router's local network that obtain their IP configuration via DHCP will then be assigned that DNS server.

Hi@trivial_factor,

Thank you for reporting your issue to our community.

Please go to the DHCP page to modify the DNS, and then fill in a meaningful DNS such as 1.1.1.1 as the secondary DNS.

Thank you.

  @trivial_factor Thank you. Does this mean I have to enable DHCP server in Pihole and reassigned all static IPs (already done so in the C80)?

Hi@trivial_factor,

As long as you have DNS setup correctly on your router, you don't need to modify the settings.
