Do you happen to have a host router upstream from the RBR? 

This will impact what version of v3 FW you can revert too...

    I do not have a router upstream of the RBR850. The RBR serves as my primary router

    Given the frustrations with this DNS server address issue I have begun to evaluate adding a Netgate pfSense device upstream of the RBR to act as the primary router and then config the RBR as an AP. At least in that network topology I can control most all aspects of the router config settings on the Netgate device w/o interference from a hawkish router manufacturer.

      Well you can try this, 

      https://community.netgear.com/t5/forums/recentpostspage/post-type/message/category-id/English/user-id/973034

      See if you can get v3, even the last version loaded. See if it blows this away, factory reset and then try applying DNS. 

      Do this off line with the RBR from the ISP modem.

      I would turn OFF the RBS and leave them alone during this process. 

       

      If it works, you can try re-updating back to v4. Leave the DNS setting in place.

        So...

        I have a POSITIVE DEVELOPMENT to report on this issue!!

         

        Before diving deeper into any further firmware back dates and script implementations in the effort to enable telnet on my RBR850 device I tried ONE MORE factory reset and RBR device reconfig with the RBR device disconnected from the ISP/WAN.


        And... SUCCESS!!

        I was able to set custom DNS server address in the Advance/Internet Setup page. See the screen grab below. Again, IP addresses and DNS server addresses redacted for security.

        And, I was able to successfully apply the DNS server settings to the RBR device and confirm through network device behavior that the network devices are using the custom DNS servers.

        So, I am HOPEFUL that the custom DNS server settings will remain persistently saved to the RBR device and that an overnight firmware auto-update will not overwite or erase the custom DNS server settings from the RBR device.

        Fingers crossed for a few more days that this works to finally solve the problem.

        I will report rmore results in a few days.

         

        Thanks again for all of the continuing forum support help on this issue!
