ipV6 disconnecting on Orbi RBR850
(NOT RBK53 model in drop down, why is RBR850 not there?) I have RBR850, firmware V4.6.7.13_2.1.9, and a CM1200 modem connected to Comcast's 1.2/40 service. All is working well, speeds, modem numb...
OK, it's been two weeks, and my IPv6 has been working perfectly all that time, no more disconnects! I am going to mark this thread as solved, with the update of firmware to 4.6.8.5 being the thing that fixed it. If others are still having trouble I suggest starting a new thread, as there may be multiple issues. Thanks everyone for your help!

Orbi reports having a LAN and WAN IP address, so the only answer seems to be the IP addresses are no longer valid at Comcast.
I too wonder why this is taking so long to fix.
I think it's a DHCPv6 on WAN issue. Comcast/Xfinity changed something in February of this year which broke DHCPv6 in certain Netgear devices. That is exactly when this started to happen on my Orbi system. This thread makes me almost sure that that's the issue:
In that thread it says:
"Yes, the Xfinity DHCPv6 PD servers appear to have shifted behavior, they now communicate via global IPv6 addresses exclusively...."
Would really like a comment on this from Netgear even if it is that I am completely off my rocker! 🙂 We are closing in on half a year with broken IPv6 on my system. That is not good.
I have been dealing with it since 2021.
