Need help getting Orbi on Same subnet as my wired devices

I recently replaced two secondary wifi routers with the RBK853 system which consists of an RBR850 and two RBS850 satellites.  The first problem I ran into is that the wireless devices can't see my wired devices which are connected to my main system router from AT&T. The DHCP server on the AT&T router is on 192.168.1.xxx while the Orbi system is 10.x.x.1.  I'd think this is my problem but I'm not sure how to resolve it.  I'd probably prefer to move the Orbi over to 192.168.1.xxx but I'm not sure of all the settings that need to change to properly make the switch. 

 

Note there is a cascaded router option on my AT&T router but I'm not sure how to set that up.  

 

Please help.

    running 2 routers in router mode does tend to create issues. 

    Its called a double nat

    https://kb.netgear.com/30186/What-is-Double-NAT

     

    options? 

    1. disable the router on the att device and put it in passthrough/modem only. I'd contact att if you wanted to do this. 

    2. Put the netgears IP address in the att devices dmz. 

    3. put the netgear in AP (access point) mode. It disables a few features but leaves the ATT router controlling the system. You still have wifi ethernet on the Orbi. This tends to be the easiest router but again, you loose a few features.

      Thanks for your reply.  I'm not sure how to do some of those things.  I would require more detailed instructions.

       

       for #1, I still have some wired devices on the AT&T devices, if I disable the router on the AT&T device will those still get connectivity?

      I don't know how to do #2.

      What features would I be losing in step 3?
