This guide shows you how to reset your Netgear WNDR3400v3 router to factory default settings. A router reset is a much bigger deal than a router reboot. A reboot happens every time a router loses power. This is different from a reset because a reset completely erases all settings from the router.

Warning: Proceed with caution; resetting your router can be a major headache. A router reset will affect the following settings:

  • The router's username and password are reset.
  • 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.
  • All parental controls, firewall settings, and port forwards 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 Netgear WNDR3400v3

On most routers you can find a small button on the back or the bottom labeled reset. A typical reset button looks like this:

Router Reset Button

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

Watch the front panel lights while you hold the reset button down for at least 10 seconds. Notice how the lights on the front of the router are blinking. When the lights do something different, the router is reset. You can hold the button down as long as you like, it will not hurt anything.

Remember, this will totally reset your Netgear WNDR3400v3 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 Netgear WNDR3400v3

Now you need to log in using the factory default username and password. We have a WNDR3400v3 Login Guide with all this information ready for you.

Change Your Password

After logging in, you should really change your router's password for added security. 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: A great place to write your new password down is on a piece of paper taped to the bottom of your router.
