In this article, you will learn how to reset your Netgear WNDR3400 back to factory settings. This is not the same thing as rebooting a router. Unplugging a router from the wall reboots it. A Router Reset completely erases the router and returns it to factory settings.

Warning: Before you continue, there are a few things you need to know. The following settings in your router will be changed:

  • The router's login and password are reset to factory defaults.
  • Your WiFi name and password are reset.
  • All ISP settings will reset to default, and you may have to contact your ISP.
  • All parental controls, firewall settings, and port forwards will be removed.

Resetting your router should be considered the last step. Make sure that you have tried to recover your router password using our Router Password Finder first.

Recover Password in Netgear WNDR3400

Instead of resetting your router back to factory settings, you may want to try running our Router Password Finder first.

Router Password Finder is designed from the ground up to help you recover your forgotten router username and password, which can save you a lot of time.

Do not do a full router reset until after you have tried every other option to log in to your router.

Reset the Netgear WNDR3400

There is usually a small reset button located on either the back or the bottom of a router. Look at your router and try to find something that looks like this:

Router Reset Button

Your reset button may look different, but usually they are very small. Sometimes the reset button is under a pinhole on the back of the router, and you need a paper clip to push it.

Keep an eye on the lights on the front of your router while holding the reset button down for about 10 seconds. Notice how the lights on the front of the router are blinking. When the lights do something different, the router is reset. It is harmless to hold the reset button too long.

Remember, this will totally reset your Netgear WNDR3400 router.

This last step should only be taken if you have tried everything else, such as using our Router Password Finder software, which can recover lost or forgotten router passwords.

Login to the Netgear WNDR3400

Now that you have finished resetting your router, you need to log in using the default username and password from the factory. Just follow our WNDR3400 Login Guide to find all of the information that you need.

Change Your Password

Be sure to change your router's default password after you get logged back in. It's a very bad idea to leave your router's password set to the factory default. You can follow our Choosing a Strong Password guide to help you pick a solid password for your router.

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