Since updating the firmware version, the router won't let me update the Primary DNS server in "Network -> Internet" page.
I get the following error "Invalid Primary DNS Server. Please enter another one."
I am trying to use pihole server as the local DNS server.

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

@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.

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
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 101, they all throw the error alert.
This used to work in the previous firmware version, I made the mistake of upgrading it and now have this problem.

@knotmine Last thought I have, is your primary dns ip address allocated through the dynamic ip pool / reserved ip or is it statically configured?

@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.

@knotmine did you find a solution to this? Having the same issue on Archer A8.
