I AM POSTING THIS BECAUSE EVERYTHING ON THIS FORM IS OLD AND THIS ISSUE IS NEW.
LOOKS LIKE MY MODEM/ROUTER INTERFACE HAS CHANGED AND WITH IT THE ABILITY TO SET MY OWN DNS.

THERE IS NO LONGER A WAY TO CHANGE THE DNS - SOME OF MY INSTALL PROGRAMS REQUIRE THAT I CHANGE THE DNS. IS THERE A WAY TO DO THIS ON THIS ROUTER - I KNOW I CAN CHANGE ROUTERS.
I'm running into this as well.My DNS prvoider is hard coded to 188.8.131.52 on my router/modem I rent from COX: https://whois.domaintools.com/184.108.40.206This is a COX run DNS server. Every time a device on your network tries to resolve a domain name (i.e. your smart TV, laptop, etc) a request gets made to COX allowing them to derive what devices you have in your house (your smarttv will phone home to a roku domain, your xbox to a Microsoft domain, etc.), what websites you frequent, and so on.I strongly suspect they are trying to monetize this data (build a profile on you about your behavior online and the devices in your home, then sell that profile to third parties). By locking down your DNS to their servers, it guarantees they have access to this data if you rent their hardware.This seems very shady.
As a solution you can plug your own router into the modem on ETH 1, set the modem to bridge mode, and it will delegate to your router. Then you can set DNS on your personal router while continuing to use the COX modem (which improves the quality of support you receive).
