    It's not optimal but in my opinion it is also not hazardous.  Many home router customers don't know what "bridge mode" is nor know how to set it up on their cable modems, therefore many people are running just fine with Double NAT. Some games may not work because of the Double NAT, it is more difficult to setup port forwarding correctly (because there are 2 router to setup correctly), and it will very likely mean you can't get full 1Gb bandwidth due to the extra overhead of the second router.  But it should still work correctly.  Some Orbi customers may be experiencing wifi disconnects and other weird behaviors caused by Double NAT, but it's unclear if that's really the cause of their issues.

Yes, for your ISP modem/router, it would be recommended to use AP mode on the RBR, then all devices will be on the same network as the ISP modem/router.

Thanks for the response, I do appreciate it.

      Thanks.

       

      If I do put the Orbi router in AP mode, I expect to see -

       

      1. All IP addressing done by the ATT router and all devices on the same network

      2. The Guest Network of the Orbi router disabled

      3. The SSID of the wireless network is still established by the Orbi router and I continue to keep the wireless network in the ATT router disabled

       

      Is those three correct?  Is there anything I should add to the list of differences I would notice?

      FURRYe38  Thanks, I understand. 

       

      The reason I am asking these questions is because the solution reccomended is not possible with the ATT router - it is not possible to put this router into Bridge mode, ATT does not allow that and hence the ATT router firmware prevents that.  So I would need to put the Netgear router into WAP mode which has the undesired side effect of removing the guest network feature, and I am not sure if it also removes other functionality I might miss.  So I want to understand which non-optimal situation I prefer to live with.
