Windows 10 Windows cannot communicate with the Primary DNS Server

So recently as I've moved home and switch to WiFi, I've been getting a heap of DNS issues with my machine. Every 10-15 minutes it'll randomly stay connected to the WiFi and report that there's no connection to the DNS (this is reported by chrome, and the troubleshooter) Whenever I use the troubleshooter, one of 2 things will happen:

  1. It will reset the router, fixing the issue.
  2. It will report that Windows can't communicate with the primary DNS server, but not fix it (however this will resolve the issue (i.e. it will start working normally again) somehow.


To fix this, I have tried quite literally, everything I can find, including

  • Automatic DNS assignment.
  • Manual DNS assignment (With Google's, Cloudflare's, and OpenDNS's DNS at the same time, in that order).
  • My PC has been rebooted as this occurs for a long time.
  • Rebooted router.
  • Every networking CMD command there is, such as:
    • Flushing the DNS
    • netsh int ip reset c:\resetlog.txt
    • netsh winsock reset

    • sc config SstpSvc start= demand

      sc config PptpMiniport start= demand


    • ipconfig /release

      ipconfig /renew
      netsh int ip set dns
      ipconfig /all
      ipconfig /flushdns


  • Changing my WiFi bands (either the channels, or the GHz band).


  • Updating drivers.


  • Using 2 WiFi ariels (sometimes one will disconnect and not reconnect for some reason).


  • Ran SFC (System File Checker).


  • Searched for WOL settings (I don't have any of these available).


  • Disabled all power-based settings (like allow it to disable the device).

Seeing as I'm needing to use my PC for an assessment in the following week, any advice is appriciated.
