With my router the only way to specify the DNS servers is under DHCP settings. There is no option for DNS servers under Internet setup.The reason I added the DNS servers explicitly on the DHCP settings was because I experienced caching issues on my Roku's if I changed the DNS servers on the router's internet settings. This seemed to solve that problem.
But I am glad you can now watch Netflix. Hopefully it remains this way and you don't have to fork out for a new router![]()
