About a week ago IPv6 quit connecting on all my devices to the Internet. After doing some research I've found that my router has the correct WAN and LAN IPs/Prefixes that are given by DHCP from my ISP. When I reach out to the ISP they tell me that "what i am seeing is your router is not sending us a RA (router advertisment) for the PD (/56 subnet)". I've power cycled the router and the ONT/modem, did a factory reset, and even rolled the firmware back to a previous version with no luck, still the same issue. All my devices have IPv6 addresses assigned by the router but I can't connect using IPv6 and attempting to ping the addresses from an outside network also results in no conneciton. What would be causing IPv6 assignments to be made correctly but then not being able to access the Internet via the Orbi? Why would the RBR750 not be sending the routing advertisements with the PD that the ISP has assigned?
Running firmware 3.2.18.1 on the Orbi and the ONT/modem is a DZS - zNID-GE-2400A1
Re: RBR750 IPv6 not advertising prefix destination
Playing around more I'm able to get IPv6 to work on my LAN devices now by enabling "Pass Through" instead of "Auto-Detect/DHCP" though it assigns addresses from the ISP's WAN and not from the /56 LAN that they had assigned me to use. So I can get IPv6 to work but it just seams that something is off/wrong having to enable pass through, would this be an issue with the ISP?
Re: RBR750 IPv6 not advertising prefix destination
Running in "Pass Through" only a few machines running Windows are getting IPv6 access/addresses other devices like my LG TVs are not able to get an IPv6 address. Very strange.
Re: RBR750 IPv6 not advertising prefix destination
If this has been working, even after a FW update, possible something with the ISP may have changed or changed and caused something in FW to break. You should contact NG support and file a support ticket:
Re: RBR750 IPv6 not advertising prefix destination
So danced between agents at Netgear and no one really knew what to do. I have to say their tech support, even the premium service, is atrocious and unhelpful. We finally got to the point that their going to replace the router, so hoping that's the fix and that the router I have is a dud. Will update this thread when new router arrives and is set up.
