How To Flush A Router Using Windows 10 & Windows 11

Why flush a router?

Flushing DNS will clear out any IP addresses and DNS records from your cache, which may help to resolve certain issues, such as not being able to see certain websites due to internet connection issues, security, and other issues.


Never adjust settings on your computer or device unless you know how to undo them!
Any adjustments you make are your own responsibility.


Let's get started. This task needs to be done using a suitable computer or laptop, not a phone or tablet.

Simple instructions with expandable illustrations of Administrator Command Prompt screenshots showing how to flush DNS in your router's Internet connection will help you do this with ease.

Flush DNS on Windows 10 & 11

First, make life easy and organise the windows on your screen:

  • To snap this browser window to the right of your screen so you can see what you are doing: Windows logo key + right arrow.
  • When you open the Command Prompt, it should appear to the left side of your screen. If it overlaps the browser window, just drag it sightly to the left.
  • After doing the router flush, you will need to restart your computer, so close all apps except the browser you are using to view this web page.

Windows 10: Type Command Prompt in the search box next to the Windows start / menu button and left-click Run as administrator (see image below).
