'DNS Server Unavailable' Error

We have all run into Internet connectivity issues at some point and we have had to deal with the many error messages Windows can throw at us. One of the more commonly encountered errors related to an interrupted Internet connection is the 'DNS Server Unavailable' error.

This article will give you a few ideas and tips you can try to troubleshoot this error and get your Internet connection back up.

First and foremost, you should be aware that in a lot of cases, the 'DNS Server Unavailable' error is causes by a connectivity problem between you and your Internet service provider or a top-level issue with your provider. Always make sure to first contact your ISP and check with them if there is a real connectivity issue or a hardware failure along the line between them and your point of access, before you try anything else.

Your ISP can either reboot the connection between them and your point of access or instruct you to do a hard reboot of your own router and that will often fix the problem. If the problem is not with your ISP, you can try one of the solutions below.

  1. Try another browser

To rule out a browser issue, it's worth keeping a secondary browser installed. In case you run into the 'DNS Server Unavailable' error and it's not an ISP issue, try another browser. This way you will be sure that it's a connection issue and not your software acting up.

  1. Restart your router

A very common way to take care of DNS server accessibility issues is simply rebooting your router. It's best to unplug the device from the power, let it rest for a few seconds so all power drains from the components, then plug it back in and check your connection once again.

The old support adage of "turning it off and then on again" will hold true more often than not in the case of this particular error.

  1. Run the Windows networking troubleshooter

You can right click your network icon in your taskbar and select "Troubleshoot problems". Windows will run you through its built-in troubleshooter and often fix the issue for you. Follow the onscreen prompts until the troubleshooter completes.

  1. Reinstall your ethernet driver

Right click your start menu button, choose Device Manager. In the device manager window, expand the category called "Network adapters". Right click your ethernet adapter and select "Uninstall device". Reboot your system and let Windows install a fresh driver for the hardware. This will often solve the issue, in case it was caused by driver conflicts or bad files.
