This guide will discuss how to reset the Asus RT-N66U router. A lot of you may be confused about the difference between resetting and rebooting. Unfortunately these two words are sometimes used interchangeably. Rebooting a router consists of cycling it's power by turning it off or unplugging it for a time and then turning it back on or plugging it back in. This will solve some lesser problems you may be having with your router. A reset is different. A reset will erase all your configurations you have ever made to your router and revert the device to factory settings.

Warning: Resetting your router can cause unforeseen problems if you don't know what to expect. Please consider the following list before you decide to reset your Asus RT-N66U router.

  • The router interface username and password are reverted to factory settings.
  • All WiFi information such as SSID, password, and authentication method are erased.
  • If you use DSL you are required to re-enter the ISP username and password to reconnect to the Internet. If you don't have this information you need to contact your ISP.
  • All configurations you have ever made are erased. This could include anything but some common ones are port forwards, IP address changes, or even parental controls.
