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!

Yes, I have seen this issue on Reddit, in another thread here and on both DSLReport and Xfinity forums. So this is not isolated to us here in this thread..
I wish there was some workaround, even on the Comcast side.

The only "workaround" is to manually disable IPv6 > Enable IPv6 with Autodetect > Wait 5 minutes > Set IPv6 to DHCP. Kinda ridiculous having to do this once a week when IPv6 drops. It mostly happens on weekends though which is good I guess?
I'm sure Xfinity/Comcast could work this out with Netgear quite easily. The question is will they, and if yes to that, when? I mean, I use a Netgear CM2000 modem approved for use on my XFinity gigabit connection so there must be some line of communication between the two.
For me last week, it happened in 3 hours. Sometimes I got 3 days, sometimes less than a day.
I just tried another test - activated IPv6 on Monday 5:30 PM EDT. I last checked it today, Wednesday 7:30 AM EDT, and it was fine. Now at 12 PM EDT, it fails all tests from test-ipv6.com and others - so it fails 38-42 hours or so later. Here is the test-ipv6.com detailed test results, in the images below. Yet the last image shows everything looking as it always does on the IPv6 advanced config page for the router. This is shameful we have gotten non reply from Netgear.
Yes, this is not good. I have never managed a network where a protocol/service just stops working and I have manually bring it back up once a week or more. I have been a Netgear nut for many years. I even bought a CM2000 modem instead of whatever Xfinity tries to push so I am heavily invested (literally) in Netgear. It's wearing a bit thin now.
I am happy to test something if Netgear wants to, if it's local to some areas and not others based on some rollout of Comcast servers, for example. This has to get fixed, this is a show-stopper if it won't ever get resolved.
FURRYe38 any chance of getting some sort of update or communication since you referred this to them months ago? I thin we deserve that, don't you?
It's in NG ball park. 😉
