V1.1.7.134_2.0.65 is my firmware. Last few days I cannot get consistent DNS working when pointed to the router DNS. If I go direct to the ISP DNS servers everything works fine. Don't see how to have DHCP deliver the ISP addresses instead of the router address.
Try setting a different DNS on the MRs web page, try cloudfare or google or qaud9.
Try a factory reset and setup from scratch.
What is the Mfr and model# of the Internet Service Providers modem/ONT the NG router is connected too? Be sure your using a good quality LAN cable between the modem and router. CAT6A STP is recommended.
