Netgear Nighthawk wrong IP address being assigned
Disclaimer: I'm not very familiar with tech terminology so please bear with me. I am having an issue with my Nighthawk routers. I have an R7000 and as of today, 2/15/23, I have an AX12. I've...
I am on a fiber optic network. The ethernet cable from the ONT box connects directly into the R7000 and now the RAX120. Yes, the AX12 I referred to is the RAX120 (sorry the box was confusing and the AX12 was far more visible than the RAX120 label). I do not know what model the ONT is as it is hard to access. If it is of any help, I am on the Frontier FiberOptic network in California. They changed out my ONT box not long ago (around 6mo ago) and supposedly I have their most updated box as of that time. If it is essential to know the model of the ONT I try to access it later to see if I can find a model number.

The biggest question about the ONT is whether or not it is a combination device that is also a router. Does it have the ability to broadcast Wi-Fi? Does it have more than one Ethernet output port? If the answer to either one is yes, that is a big part of the problem. Two devices on the same LAN trying to perform routing functions is problematic. The model number for the ONT would confirm the answer to the question. Your IP address issues and lack of access to the internet are classic symptoms.
So you have set the R7000 aside and now have the RAX120 connected in its place?
As I understand it the ONT is not a router. It does not appear to broadcast its own wifi signal. I know this because even if I pull the plug on the ONT box, all the wifi signals I can connect to are the same so should either be that it is not capable of wifi or that wifi is not in operation. As far as I know, the ONT only has a single ethernet output port. If there are more, then only one had been in use and it had been connected to my router.
I have set my R7000 aside and am currently using the RAX120 connected in its place. As additional info, I also run a Linksys switch for additional LAN connections but even my PC LAN connections that are connected directly into the RAX120 are getting incorrect IPs. The switch does not have wifi capability and can only do LAN connections. I have already tried disconnecting the ethernet for the switch while connecting my other LAN connections to the RAX120 and it does not solve the issue.

As long as your switch is connected downstream of the RAX120 it should work fine. What is the brand name and model number of your switch?
Your Ethernet connection should run through a single cable from your ONT to your RAX120 then to a computer if possible. Using DHCP your RAX120 should assign IP addresses to all devices downstream from a pool of addresses. Your RAX120 configuration sets the IP start point, such as 192.168.2.100 through 192.168.2.200.
The ONT replacement a few months ago is still a possible start point. There is a chance the ONT itself reserves a LAN address for itself that is in conflict with the RAX120.
It is becoming more important to know the details of what is on the label on your ONT. In fact a cell phone picture would be helpful.
How long has it been since your powered down your whole network and did a sequential start? The sequential start begins at the outside and works its way in. Power down does not mean just shut off the switch, it means pull the power cord. Pull the power cord to your ONT, disconnect the output Ethernet, pull the power cord on your RAX120 and disconnect all the Ethernet connections. Power down the remainder of your network devices. Go back to your ONT, power it up and give it ample time to start and stabilize. Connect the Ethernet to your RAX120 and power it up. Give it plenty of time to boot and stabilize. One of the last indicators to illuminate should be your internet connection. Connect an Ethernet to a computer and boot it up. Access your RAX120 user interface and check the IP addresses and run a throughput capacity test to the internet. If you don't have a computer with an Ethernet port input, you can connect via Wi-Fi from the RAX120 and do the same thing.
Connect and power up the remainder of your network devices. The IP addresses should all be within the range you set in your RAX120.
Does your ISP support IPv6? If it does, you should enable IPv6 support in your RAX120 configuration.
