@terziyski for some reason, it only worked intermittently for me. Don't know if the router falls back to DNS servers on the "Internet" page to resolve

@Kahakqnj I disabled the DHCP server on the router and using the one on pihole in raspberrypi.

@eousphoros It's a reserved IP. (I changed it back to 192.168.0.100, so it looks different from original screenshot) Still, only reaches out to local DNS intermittently.

@eousphoros You can see the subnet mask in the "Internet" page on first post LAN settings: IP Address: 192.168.0.1 Subnet Mask: 255.255.255.0 I have tried different numbers from 192.168.0.1 through...

This obviously looks like a bug introduced in the new firmware update. Can someone acknowledge or add to your bug fixes? Meanwhile, which version can I safely go back to for this router?

@eousphoros I tried blank as well. The problem is always that primary DNS field is not valid. It works fine if I put 8.8.8.8 in the primary field. Seems to not like local IPs.
