This guide shows you how to reset your TP-Link Archer MR400 v4 router to factory default settings. Resetting a router is different than rebooting a router. Rebooting a router is simply turning it off and back on again. A Router Reset completely erases the router and returns it to factory settings.

Warning: Make sure that you fully understand the following before resetting your router. A router reset will affect the following settings:

  • The router's username and password are reset to factory defaults.
  • All WiFi settings are reset, including network name and password.
  • Your ISP username and password will be reset, and you may have to contact your ISP.
  • Any firewall settings, parental controls, or port forwards that you have configured will be removed.

A router reset should be considered the last resort when you cannot log in to your router any other way. Make sure that you have tried to recover your router password using our Router Password Finder first.

Reset the TP-Link Archer MR400 v4

Most routers have a small button on either the back or the bottom. This is what a typical reset button looks like:

Router Reset Button

Even though yours may look slightly different, you need to look for a tiny button. If you find a pinhole on the back of the router then that may be the reset button. You will need a paper clip to push it.

Hold the reset button down for about 10 seconds while watching the lights on the front of your router. You should notice that the blinking pattern of the lights on the front of the router changes after a few seconds. You can hold the button down as long as you like, it will not hurt anything.

Don't forget, this step will totally reset your TP-Link Archer MR400 v4 router back to factory settings.

Be sure to only reset your router if you have tried everything else, such as running our Router Password Finder software, which can find your lost or forgotten router password for you.

Login to the TP-Link Archer MR400 v4

Now you need to log in using the factory default username and password. Our Archer MR400 v4 Login Guide has all of the information that you need.

Change Your Password

Do not forget to change your router's default password when you log back into it. It's a very bad idea to leave your router's password set to the factory default. If you need help coming up with a strong password, check out our Choosing a Strong Password guide.

Tip: Put your new password on a post-in note and stick it to the bottom of your router.
