@Kevin_Z this is not a good feature. It is buggy and breaks my network. Please remove from all modems OR AT LEAST GIVE US AN OPTION TO DISABLE IT!

 Please remove this unprecedented feature from routers. Router should not change it's setting on its own.

Same problem. AX3000 or Archer AX50 but different LAN IP. The router won't keep the LAN IP. I want a 192.168.0.1 network, ninor devices (mostly WiFi connections use the router DHCP, the other have fixed IP and it keeps resetting to 192.168.1.1.

When I loose internet, the stupid router pop ups a warning "To avoid IP conflict with the front-end device, your router's IP addess has been changed to 192.168.1.1"

Is there a way to avoid this, it happens when I am transfering havy things on the net.

Thanks in advance.

@Kevin_Z 

hello, I am having this problem with my Archer C6 router changing its own IP address from time to time, and I did set DNS servers to be external. I used Cloudflare's 1.1.1.1 and 1.0.0.1, going to Advanced > Network > Internet.

My ISP is a coaxial cable TV operator and I've set their cablemodem to be bridged mode, thus my public IP address got fixed and I think it's binded to my router's MAC address, which was already connected at the time of setting the ISP's router to bridged mode. However the tp-link router is set to Dynamic IP. Could this be the problem? Everytime I reset it, it takes a while but it finally gets the same WAN IP address, but I would like to leave it as dynamic because I am not sure whether or not my ISP will ever change my public IP and default gateway.

Now I've read your post and I've set Cloudfare DNS servers also in Advanced > Network > DHCP Server, with Default Gateway being the router's IP address as set on the LAN page. Do you think it will be fine now?
