    I wish you posted the output of nslookup example.com 8.8.8.8, I was hoping to see evidence of your ISP redirecting DNS queries to themselves

    >> There is no menu on the router app to change that setting. Looked at every option

    Look in your DHCP settings on the lan

    what happens if you go to example.com's IP
    93.184.215.14

    Yes, that is the strange part for me also, looking at itself. The DNS2 ip goes to Century link [now Quantum] 205.171.2.26. I cannot tell if that is a DNS server or not or just a call home address. There is no menu on the router app to change that setting. Looked at every option??? Yes I have done nslookup to 8.8.8.8 and 1.1.1.1 and they appear "normal". I wish I understood networks to a greater degree. :)
    open command prompt
    Type:
    tracert one.one.one.one
    hit enter
    see what times you get on the route to cloudflare dns

    then test again but with IP
    tracert 1.1.1.1

    The first one will trace the route with DNS query.. the second one will trace on IP without trying to resolve the IP for the domain, but it is still the same server, so it should be almost the same times.
    If it takes longer time for it to start tracing the route on the first one but not the other one.. Then the DNS query is slow. And you will see what nodes are slower then the other..
    with satellite connections up to 500ms will not be extreme slow even it is slow.. around 100ms with cable is slow, but not extreme slow.. around 50ms with fiber is not extreme slow even it is slow.
    if you using Wifi.. test again with an Ethernet cable and see if times becomes better.

    The first route you will see is between your computer and your router.. the next one is the ISP and so on and the last one is cloudflare DNS 1.1.1.1 or the domain name one.one.one.one

    Then last.. run a speed test Speedtest by Ookla - The Global Broadband Speed Test

    If your Gateway/Router does not have the option of changing DNS servers, then change it in the Web Browser.
    e.g. Edge Browser > Settings > Privacy, search, and services > scroll down, to Security > Use secure DNS toggle on ... Choose a service provider. Mine has several choices by default.

    UPDATE: In desperation, I decided to use my new router [ASUS] and connect it directly to the ONT. This bypasses the isp router and everything connected to the new router, TV, PC, Voip works at top speed and without any buffering. So my conclusion, the configuration of the isp router [DNS x] points to the failure. Called isp, they have no record of my appointment, [PMO!]so established a new one this Thursday. Will allow the tech to figure out whats wrong with his router. In the mean time, configuration of all my devices to new ip's is a giant PITA. i.e. Sprinkler controller, would not allow selection of new ip, finally changed the location from approx to precise location did the trick. Thanks for all the help here, I think I see some light at the end of the tunnel.

    Tx Helmut for that tip. that question led me to this initial subject of the thread. If the router sets the DNS, then does the browser DNS setting over ride it? I did a comparison and they did not match.

    Browser > Windows > Router (as long as internet works, a custom DNS set in either above will overrule the router)

    Today, isp Tech #2 show's up and takes one look at their router and says "that's the wrong router and that one is not compatible with the ONT that you have"??????. SO, you have a choice of using your own router or you can order mesh router pods at no cost from our isp store and DIY the install. There is plenty of video's on line or call our tech support if any problems. He tossed the isp router in the back of his van and said have a great day. Got on line, ordered 3 and now waiting for delivery and possibly another cluster getting them to operate.

    Finally all ok with the system. Received 3 new pods, got them installed and everything is back to better than before. Thanks to all who had input and provided assistance. Now closing this thread and marking it as solved.
