This would be a double NAT (two router) condition which isn't recommended. https://kb.netgear.com/30186/What-is-Double-NAT

This could also lead to seeing problems if you have the RBR in router mode with the ISP modem/router.

Which modem? As I siad the orbi is in router mode as I want that to be my home control point (50 devices connected). The xfinity is just my gateway enabled ISP, wifi is turned off and it is not in bridge mode.

The xfinity ISP gateway is:

Model: CGM4331COM

Product Type: XB7

I have not put the RBR's IP address into the DMZ or pass-thru. Not sure why that is needed and can't be managed automatically as they will change. Can you clarify that?

I'm not having any network issues in the house and performance is good. I tried putting the ISP xfinity XB7 in bridge mode and the orbi lost internet connection. This is likely as I have a TRENDnet 5-Port Unmanaged 2.5G Switch that I use to increase # of 2.5 GB feeds to orbi and other computers that can take advantage of them given XB7 only has 1 port of 2.5 GB. So not sure I want to put orbi in AP mode or further make change that wont benefit me.

You have to power OFF both modem and RBR after you bridge the modem for 1 minute then back ON with the mdoem, then the RBR to make the modem connect to the RBR.

Ya, after you bridge the modem, move the switch to after the RBR when the modem is bridged and the RBR is in router mode.

Wondering if this configuration your using is causing memory creep for your system....

Please do NOT attempt to downgrade your Orbi systems from this version of FW back to v4.6.3.16 or anything older.
Were seeing some users post that there systems are not functional or not working right at all after they downgrade using normal downgrade proceedures.

If you system is not work right after updating FW, post here in the forums and we'll try to help you out and troubleshot the problems.

Leave the FW version on the system as is.

I"ve passed this on to NG for review and information.

Thank you.
