[SOLVED] Router automatically changing its IP

[KillBot]

I just replaced my fios router with a TP-Link AX 1500 (ver1.2). I set the new router to use 192.168.1.1 as its ip instead of 192.168.0.1 (default). I also set the DHCP range from 192.168.1.3 to 192.168.1.99 so it doesn't conflict with static IPs on my network (100 up). Everything was working fine for a few minutes and then the router changed its IP back to 192.168.0.1 on its own. There was a message that it was changed automatically to avoid a conflict.

Any idea why it would change automatically? Its address (192.168.1.1) was the address the fios router was using so there is no conflict.. I am trying to avoid having to change the static IPs of a few headless raspberry pis on my network. (pihole, media server, security cams).

Thanks!

Any of these devices acting as DHCP as well? Check your PiHole, it has this option

No, no other devices are DHCP servers, including the piholes.

Run "arp -a" via the Command Prompt.

First when the router is 192.168.1.1 and then again after the router reverts to 192.168.0.1.

Compare devices, MACs and IP addresses (both DHCP and static).

Thank you. Will do if it does it again. I changed it back to "1.1" and its been fine for 12 hours. If it stays that's fine but it's still going to bother me not knowing the cause. Could the Verizon ONT have caused it to believe the "1.1" address was taken?

The ONT should be giving the WAN port a public IP address. This would be more if you left the verizon router in and then ran router behind router. They complain when the wan and lan are the same range.
