Bridge mode and AXmode

My problem is the that my IP standard modem/router uses 192.168.178.x as its ip address base.

The Orbi uses 192.168.1.x

I have switched wifi off on the IPs modem/router. But it still generates ip addresses for equipment that is connected by ethernet.

This is a classic case of "double NAT".

As you have discovered, two routers on your network can cause headaches. For example, you can end up with local problems with address on your network. Among other things, the other router can misdirect traffic to addresses that the Netgear router usually handles, such as routerlogin.net or the usual default IP address for a router, 192.168.1.1.

This explains some of the other drawbacks.

What is Double NAT? | Answer | NETGEAR Support

Unless you have specific reasons for using two routers – to create two separate networks for example – it is often easier to use just one router and then to set up the second router as a wifi access point (AP) with a wired connection to the main router. Netgear advises this, as does just about every site you will visit.

My NETGEAR or Orbi router is connected to an ISP gateway or another router, and it's causing double NAT problems. How do I fix them? - NETGEAR Support

But that has its own drawbacks:

Disabled Features on the Router when set to AP Mode | Answer | NETGEAR Support

It may be possible to put the modem/router into modem only (bridge) mode and then to use the second device as the router. But some Internet service providers, such as BT in the UK, supply modem/routers that won't work in bridge mode.

This does not disable the first router.

I think that another option would be to put the ORBI in bridge mode. It is essential though that AX mode not be enabled as this is creating problem's with some of my equipment. Eg Foscam IP camera and RIng doorbell

Not sure that bridge mode is available there. (That term means different things depending on the context.) Perhaps you mean AP mode.

Are you sure that these problems are not the result of the double NAT clash?

There is another option, put the Otbi into the "DMZ" for the anonymous modem/router.

Set the modem/router with a local IP address that does not clash the Orbi. (I opted for 192.168.2.1.) Then look at whatever IP address the modem/router has allocated to the Orbi and put that as the "DMZ" in your modem/router.

I left everything else untouched.

You will still be able to access the controls of the modem/router through its IP address while the GUI for the Orbi is still there on its local address.
