RBR850 IPv6 dropping from Xfinity XB7 hourly
I have searched and searched and cannot find the answer to this issue. I have the RBR853 mesh system. Xfinity gig internet. I have no problem pulling a IPv6 address from the XB7 modem. And the Or...

That said, would turning off the routing functions keep the satellites from working or cause other significant losses? I have an Xbox wired to one of the satellites and the modem (XB7) and router (Orbi) are in the center of house. The Xbox is in a corner. It needs the wired connection to a satellite to function well.
I also have a similar setup: XB7 + RBK754 + IPv6 enabled + Brigde mode initially, but I've since switched Orbi to AP mode.
XB7 routing + DNS + DHCP + IPv6 functions are already validated by Comcast within their network/servers and Orbi is a WiFi beast in AP. If Comcast makes any change to their internal servers or XB7 firmware, I don't have to worry about compatibility issue with XB7 not wrking after XB7 firmware update or Orbi firmware update.
This setup will help me avoid any potential compatibility issue between XB7 DNS/DHCP (IPv6) servers and Orbi. I also get FREE parental control, which is disabled with XB7 in Bridge mode. XB7 parental control is a big improvement comparing to paid Orbi parental control.
Unless you're using a specific feature that's only available when Orbi is in Router mode and that feature is missing from XB7 as well, switching to AP mode will simpify your WiFi network with less headache due to compatibility issues as a result of firmware updates.
Everything seems to be working still. Good speeds. IPv6 holding. FW updated. No issues anymore, and I think my overall wifi coverage is actually better.
I'd consider this one solved and will mark the solution. Thanks all!

Good to hear it's working out.
Just in case, Orbi (RBR850) WAN port is capable of 2.5Gbps, make sure you connect Orbi WAN port to the right XB7 2.5Gbps LAN port. Also, If you haven't already, make sure you disable WiFi on XB7 to avoid interference because Orbi uses all 4 lower 5G bands. Keep the XB7 WiFi off as a backup (same SSID).
Have fun!
I think I have done this -- cutting off wifi on XB7 -- but to make sure, what steps did you take? And how can I confirm that only the Orbi is sending out wifi and not overlapping with the XB7? Is that something the Xfi app handles or admin site?
You can confirm WiFi is disabled in the XB7 "At a Glance" page when you login.

My XB7 admin site, when in bridge mode, is still accessible at http://10.0.0.1/. Since yours is no longer in bridge mode just use the gateway IP.
