Disable auto change IP address

In an earlier post, we talked about a tracert test to demonstrate where the public and private IP addresses started and stopped... that may be useful here.

Can you try and tracert a site, say microsoft.com and post the results here?  It may show that double NAT condition.

Yes, let's assume I've got no idea what I'm talking about. Here's your traceroute. No, there is no double NAT.

Please, read my actual posts. I get a private IP while the cable modem is connecting. This IP is 192.168.100.0/24. That does not conflict with my Orbi internal network of 10.99.99.0/24. Orbi still loses its mind every month when my cable modem resets and grabs a new IP. The RFC 1918 address is assigned - again, always 192.168.100.0/24 and never conflicting with 10.99.99.0/24. After that, the link is dropped and brought back up and the Orbi is *OFFERED* a public non-RFC 1918 address which it does not take. Still, Orbi loses its mind.

Eventually it appears the Orbi itself goes into bridge mode and I end up with a public IP in the 45.36.x.x-45.37.x.x range on the INSIDE OF MY NETWORK. This means only a single device in my house among a hundred or so devices gets to use the internet. Nothing else gets an IP because my ISP only allows a single public IP.

This is even more confusing because the Orbi still sits flipping between RFC 1918 addresses as if it is detecting a conflict while in bridge mode.

Often times I have to unplug the Orbi from the cable modem and reset the Orbi router to get it to stop flipping IPs. After that, it still comes up one last time with the IP conflict detection page, then I'm able to change it because it stopped running from imaginary conflicts.

No, I won't take a picture of my cabling. There are no devices besides the cable modem plugged into the Orbi (this is the purpose of wireless mesh, no?). Yes, it is in the correct yellow internet port.
