NIght hawk/Windows IP address conflicts

I have a Windows 10 PC with a Night hawk wifi router.  The pc is connected to the router via cable, all connections to other devices in my home are wifi.  Windows 10 consistently pops up error messages stating I have duplicate ip addresses and device conflicts.  I have checked the routers list of ip addresses and there are no duplicates.  What do I need to do to elimiate these error messages?

       I'd tend to believe it.  Does it mention any actual IP addresses?

       Are you talking about an Attached Devices report, or what?

       Eliminate the IP-address conflict(s)?

     

       How is the Ethernet interface on the Windows system configured?
    Hint: If it's not "Obtain an IP address automatically", then it probably
    should be.

    The error message does not mention any ip addresses.  Its seems to be a stock Windows error message, no details.

     

    I obtain a list of connected IP addresses through the night hawk router web interface.  There are no duplicate IP addresses at all.  

     

    How do I make the config change you mention?  I searched in google but instructions were incomplete and mostly inaccurate.

     

    Thanks for the help

         And the title there is...?

         If your Windows system noticed that the IP address which it expected
      to use was already in use, then it might complain, rather then set its
      own address to some known-conficting address.

         It's a Windows question -- not my specialty.  I'd look at the
      Properties of the Ethernet adapter.  There should be innumerable
      explanations on this new Inter-Web thing.  It seems to get mentioned in
      this Netgear KB article:

         Look before you change anything.


         For that particular disaster-recovery situation, setting static
      parameters ("Use the following IP address", [...]) is required.  What
      you want is the clean-up afterward: "Note: Please remember to change
      your PC back [...]".  Assuming that that was your original problem
      (which is not yet clear, but is still my guess).
