RBR850 Can't get internet from Xfinity xFi Gateway
Hi, I've spent about 9 hours on this today, so really hoping someone here has some ideas to break the logjam! I've got an RBR850 and 5 RBS850's. FW 7.2.6.31. I've been using them for a few years ...

Yes, that's what's strange to me. Because the xFi is definitely connected to the Orbi and it's definitely connected on the yellow Wifi WAN port. And the Connected Devices list shows the MAC address of the modem, so it's "seeing" the modem somehow, which again is connected to the yellow WAN port.
Also, nothing is connected to the LAN1 port, but there's activity showing there.

I am sometimes too fixated on terminology. In this discussion, the term modem can refer to
- The Netgear CM1100 modem, or it can refer to
- The xFi box? (which specific xFi is this?)
At no time are both the CM1100 and the xFi operating at the same time?

After from the brief period of time that the Xfinity agent was trying to help me swap back to the CM1100, which is when all this trouble started, I have been exclusively using the xFi XB8 Gateway. That's the modem I'm having all the trouble with.

Thanks for being patient. Is there a specific reason to put the XB8 into Bridge Mode?
- popechild2Jul 14, 2024Guide
I'm using the RBR850 as my router along with 4 satellites to ensure full coverage in our house. In order to use the RBR850 as the router, the xFi needs to be in bridge mode. The XB8 can't cover the full house.
I've used the RBR850 and satellites for quite awhile now. And for the last 6 weeks have used it with the XB8 in bridge mode. So something has obviously changed which is preventing it from working now. Since the XB8 still works in bridge mode with the Netgear Nighthawk, it would seem to indicate the problem is with the RBR850.
