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 ...
So this seems weird to me. Looking at the RBR850 admin page, can someone help me decipher this?
ModestMBA is the laptop I'm using. The other device (C4:50:9C:42:A6:B6) is my modem. Is it normal that the router would be assigning an IP address (192.168.1.3) to the modem? That isn't what I would expect and seems to be indicating that it doesn't realize the modem is a modem or something?
Then in the image below, there's no activity showing but there IS activity showing on LAN1. The only ethernet cable connected to the router is on the yellow LAN port (visually double-checked). Wouldn't I expect to see activity showing here on the WAN port and not on the LAN1? Taken together with the IP address thing above, it almost seems like the RBR850 thinks the modem is actually connected to LAN1 instead of WAN, and therefore doesn't know it's a modem and is instead trying to assign an IP to it like a regular connected device. But I'm not sure if that's just me not understanding how this typically works?

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.
