If you need to reset your TP-Link TL-MR3420 router back to factory settings, then this article shows you how. A router reset is a much bigger deal than a router reboot. Unplugging a router from the wall reboots it. Resetting a router erases all settings from it and returns it to factory defaults.

Warning: Since this erases everything you have done to the router, there are some things you need to consider first. The following settings in your router will be changed:

  • The router's login credentials are reset to factory defaults.
  • All WiFi information such as network name, password, and authentication method are erased.
  • Your ISP settings are reset, which means you will have to contact your ISP to get them back.
  • Any firewall settings, parental controls, and port forwards that you have configured will be removed.

A router reset is the last step you should take in recovering your router's password. Make sure that you have tried to recover your router password using our Router Password Finder first.

Use a VPN Instead

Have you considered using a VPN instead of forwarding a port? For most users, a VPN is a much simpler and more secure choice than forwarding a port.

We use and recommend NordVPN because not only is it the fastest VPN, it includes a new feature called Meshnet that makes forwarding a port no longer necessary for most applications. With NordVPN Meshnet, you can connect to your devices from anywhere in the world, completely secure, over a highly encrypted VPN tunnel.

When shopping for a VPN, make sure that they meet the following criteria:

  • Your VPN provider should have a no-logs policy. This means that they do not keep any logs of any kind.
  • Make sure that your VPN provider has lots of exit nodes all around the world.
  • Check that your VPN will not affect your speed.
  • Verify that your VPN provider uses WireGuard as the underlying protocol.
  • Many people prefer a VPN provider that is not based in the United States.

This is the list of requirements that we used when we were shopping around for a VPN provider. There are lots of free, shady VPN providers out there that we looked at and dismissed.

Based in Panama, using diskless servers, and with over 6,100 servers in 61 countries, we can safely say that NordVPN satisfies all of these requirements.

NordVPN faster than ever deal!

Once you've set up your NordVPN account on multiple computers and enabled Meshnet, you can seamlessly access all of your devices as if they were on the same network. You don't even have to log in to your router. It's very simple.

Every time you click on one of our affiliate links, such as NordVPN, we get a little kickback for introducing you to the service. Think of us as your VPN wingman.

Most of the time you can find a small reset button located on either the back or the bottom of a router. This is what a typical reset button looks like:

Router Reset Button

Your reset button may look different, but usually they are very small. 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. After a few seconds the lights should blink differently. When this happens, the reset is complete. You cannot hold the button too long, and it will not hurt the router to hold the reset button down for longer than 10 seconds.

Remember, this will erase everything you have previously done to this TP-Link TL-MR3420 router.

Only do this once you have exhausted all other troubleshooting options, such as running our Router Password Finder software, which can recover a lost router password for you.

Login to the TP-Link TL-MR3420

Now that you have finished resetting your router, you need to log in using the default username and password from the factory. Our TL-MR3420 Login Guide has all of the information that you need.

Change Your Password

You need to change your router's default password after you log in for the first time. Since factory passwords are well known, it's a huge security risk to leave your router set to the default. Our Choosing a Strong Password guide can help you pick a strong password for your router.

Tip: A great place to write your new password down is on a piece of paper taped to the bottom of your router.
