RBR 850 firmware v7.2.7.15, I just read on the netgear site this firmware is a problem for ipv6 and to set back the firmware to a previous version. I have checked my router settings many times in the advance ipv6 settings, currently set to DHCP

 

any thoughts from anyone who has experienced problems with ipv6 connection issues would be greatly appreciated. Thanks,

      Yes, FURRYe38 is correct. I have tried v7.2.7.15 &  v7.2.8.2. IPv6 drops on both versions.

       

      Worked just fine with no dropping with prior firmware versions. I am currently running V7.2.6.31 with no issue. Also had no issues with several previous versions prior.

       

      Issue began starting with v7.2.7.15. I have exhausted all the mentioned troubleshooting steps in previous threads. Something was introduced or excluded with v7.2.7.15 and 

      v7.2.8.2 for the dropping to begin.

       

      My ISP is Cox. I am on a fiber connection from a Nokia ONT

        Just checking, are you using detected ISP IPv6 DNS or custom IPv6 DNS?

         

        How is the RBR configured for IPv6, which mode are you using from the IPv6 drop down menu?
