RAX45 "The IP address conflicts with the WAN IP subnet. Please enter a different IP address."
I am trying to add a Netgear Nighthawk RAX45 WiFi-6 to my network My modem is a Modem/Router Netgear N450 (Cox) There is also a Router Belkin 54G F5D72304 When I get this working, I want to repl...

Nothing I can do about that, whatever it means.

Not much meat on that bone.

That's typically a good way to restore normal operation after
misconfiguration.

You, personally, are "connected" to what? Some computer or other is
connected to a LAN port on the RAX45, or the CG3000Dv2, or what,
exactly? Wireless devices are on your LAN, too, but I'll take that as
meaning an Ethernet connection between something and something else.

Which one? A router has two: LAN and WAN/Internet.

"Netgear" is a corporation, not a web site. Actual URL? And this is
with what as a modem, and what as a router, connected how?

Doing what? Connected to what, how? (Hint: If a device has
different types of ports, then "connected to device" is not enough
detail.)

The "fix" is not to try to configure the WAN/Internet interface of
the router on the same IP subnet as its LAN interface.

I'd say that the bad idea was trying to use a CG3000Dv2 as a cable
modem-only when it apparently has no such mode of operation.

If I wanted to make the RAX45 work, then I'd get a cable modem which
will work with your ISP. If they can't puzzle out the CM1100, then I
might try a different maker and/or model.

What's to "build up"? With a working router, you should be able to
set the router's LAN IP address as you'd like it, and the wireless stuff
(SSID(s), passphrase(s)) to what you had before. Then, with a working
modem, I'd expect all your client devices not to know the difference.
I see that I overlooked this earlier:

Every network interface has a MAC address. A router has two network
interfaces, LAN and WAN/Internet. Which MAC address you want depends on
the interface of interest. I'd expect both to appear on the ADVANCED >
ADVANCED Home page in the router's management web site.
I have a desktop computer directly connected to a wired LAN port.
Restoring the CG3000Dv2 router to original settings got me back to where I was before. And I am back on-line.
The Modem LAN IP was changed. I don't know to what. I couldn't connect to it at all, thus the reset. But the IP inconstincies reaked havoc throughout my network. I could get to Facebook, but the website for THIS forum (https://thf-membership.s3.amazonaws.com/2019_08_0309_GunControlEBook_V5.pdf?mkt_tok=ODI0LU1IVC0zMDQAAAF9XnvpZjEpYiIkxNzD3-RKlTfihFOQT4jBs2K-baF7LrOQ6XQk_ttkQ3HR2INWKALiObrZlmo2nRYikfxRE0zT9MtUhGaSizyrl0bf61DzcQVqucjd) was totally unavailable. Gmail was completely baffeled by the conflicting IP addresses and shut me down-also wouldn't let me enter passwords either. Using the CG3000Dv2 modem/router with an unknown IP address. I assume it was the LAN IP address since I couldn't connect to the modem through the LAN.
BTW, the CM1100 is specifically identified as being compatible with COX.

Exactly what I would expect, what I have done in the past with outher routers (even with multiple routers) and as long as I set the routers IP addresses not to conflict with other devices, it has worked. I will keep trying.
Try again.
“The IP address conflicts with the WAN IP subnet. Please enter a different IP address.”
Still getting this error when I try to create a local subnet.
LAN Setup
Device Name : RAX45
LAN TCE/IP setup
IP Address 192.168.56.200
IP Subnet Mask: 255.255.255.0
RIP Direction: Both
RIP Version: Disabled
Use Router as DHCP Server
Starting IP Address 192.168.56.201
Ending IP Address 192.168.56.254
“The IP address conflicts with the WAN IP subnet. Please enter a different IP address.”
So look at WAN IP:
WAN Setup
N Disable Port Scan and DoS Protection
N Default DMZ Server 192.168.1.0
N Respond to Ping on Internet Port
Y Disable IGMP Proxying
MTU Size(in bytes) 1500
NAT Filtering Secured
(Absolutely nothing here about WAN IP Subnet)
Internet Setup
Does your internet connection require a login? `No
Internet IP Address: Get Dynamically from ISP (but doesn’t matter if I try to use a static address)
Domain Name Server (DNS) Address Get Automatically from ISP
Router MAC Address Use Default Address
So the message provides no information about what is causing the error. Lot of people on the boards have this error and have difficulty fixing it. There are not IP conflicts using 192.168.56.200-192.168.56.254. There are other devices using 192.168.56.xxx but not this block. I have used multiple routers in this network in the past, including Netgear, and as long as the addressing doesn't conflict, there has not bee a problem. The error message is not useful in solving the problem.
It will let me use 192.168.1.xxx but I don't want to use that.
