@SDHINESHKUMAR

What is the network layout? Is there another DNS server in your network?

You can try to set the DNS servers in the WAN/Internet page instead of the DHCP server, will it also reset?

@Liverpool20

What is the network layout?

TP Link Archer C80(WAN) is connected to my Physical Server Secondary NIC(which go through Pfsense(VM)) and Primary NIC is connected with Internet.

Is there another DNS server in your network?

Yes, I have my own Windows DNS Server(VM)

You can try to set the DNS servers in the WAN/Internet page instead of the DHCP server, will it also reset?

WAN/Internet page set DNS Servers are working fine, I dont have any issue.

Primary DNS Server Set is : 192.168.X.X(My Own Windows DNS Server)

Secondary DNS Server Set is 123.X.X.X(My ISP DNS Server)

Pls make note it was work fine before the Firmware Version: 1.12.0 Build 221010 Rel.35508n(5553) upgrade.

@Kevin_Z

I'm having the exact same issue as @SDHINESHKUMAR, with the exact same firmware version, but for a different model --- here's my info:

Firmware Version: 1.12.0 Build 221010 Rel.35508n(5553)

Hardware Version: Archer A8 1.0

So while he has the Archer C80, I have the Archer A8, with the same firmware versions and the same exact problem -- when I set the Primary & Secondary DNS to my local DNS server and save it, everything works like a charm....

...until I reboot the router, and then the DNS setting reverts back to the gateway IP.

Any chance the developers have a firmware fix for my model as well? I just purchased this router and love it except for this one big problem.

@ThereIsNoSpoon We will soon check with the developers to see if they can provide a beta firmware for Archer A8 as well. Please wait.
