IPv6 quits working shortly after enabling it.
Modem: Arris SB8200
Provider: Xfinity
RBE970 firmware: v9.11.0.1
Ethernet: Cat6 verified (not fake CCA Ethernet)
IPv6 is supported (works fine with my RBR750 Orbi system)
IPv6 settings: DHCP and the LAN is set to Auto Config

OK, There seems to be already a known issue with IPv6 and Orbi 970 series. Something that NG is aware of. No idea when a fix will be forth coming. You might want to contact NG support and let them know as well of what your seeing.

One thing to try is a different DNS server. I had issues with IPv6 and Comcast on a couple of different firmware versions. For some, it'd be rock solid, and for others, it'd drop immediately. I use a pi-hole, and once I switched both the ipv4 and ipv6 DNS servers to my pihole, my ipv6 has been rock solid.
Here are a few you can try without having to install your own pihole.
Also, remember to change the ipv6 dns server.

IPv4: 1.1.1.1 and 1.0.0.1
IPv6: 2606:4700:4700:0:0:0:0:1111 and 2606:4700:4700:0:0:0:0:1001

IPv4: 8.8.8.8 and 8.8.4.4
IPv6: 2001:4860:4860:0:0:0:0:8888 and 2001:4860:4860:0:0:0:0:8844Again, not 100% sure it'll work as I'm running through my own DNS server but its worth a chance if its the IPv6 DNS server causing the issue.
