Right off the bat, the most popular fix is to restart your router¹. Yes, it’s that simple. Turn off the power supply to your router and leave it off for about 10 seconds. Restart the router by turning the power on again.

And, for good measure, restart the device that is experiencing the DNS problems as well. Once everything restarts, test your internet connection to verify that it is working, if not continue with the tutorial.

Reset IP and DNS

By default, a computer is set to use the DNS configured on your router or modem. Your internet service provider provides the DNS settings, and they remain the same unless changed. If there is an issue with your DNS configuration, then you can modify the settings and use a public DNS server. Follow the steps outlined to do so:

  • Hold the Windows key and press R
  • In the run dialog, type cmd and click OK
  • When the Command Prompt window opens, type the following in it and Hit Enter.

The ipconfig /flushdns command flushes the DNS cache. A flushed cache erases any modifications int he DNS settings and the system. For a more in-depth, full proof method, use the information below to reset your IP and DNS settings.

Open a Windows Command Prompt window as outlined above and run the following commands. Each line of code must be entered separately. After you enter one code, hit Enter on your keyboard and then do the same with each other code per line.

netsh int ip reset
netsh winsock reset
ipconfig /flushdns
ipconfig /renew

Once you complete the above steps. Restart your computer. Upon a successful restart, Windows reorganizes your records and the record causing the error is deleted and replaced. Check to verify that your internet connection works correctly. If not, continue with the tutorial.
