If you need to reset your Netgear WNDR3400v3 router back to factory settings, then this article shows you how. A router reset is a much bigger deal than a router reboot. Every time your router loses power it reboots. However, when you reset a router you, return it back to its factory default settings.

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.
  • Your WiFi name and password are reset.
  • All ISP settings will reset to default, and you may have to contact your ISP.
  • 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. You should be sure that you have tried to at least recover your router password using our Router Password Finder before resorting to a router reset.

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 routers have a small button on either the back or the bottom. A typical reset button looks like this:

Router Reset Button

Reset buttons are usually tiny. Yours may look slightly different than this. Sometimes the reset button is under a pinhole on the back of the router, and you need a paper clip to push it.

Watch the lights on the front of your router and hold the reset button down for about 10 seconds. After a few seconds the lights should blink differently. When this happens, the reset is complete. It is harmless to hold the reset button too long.

Keep in mind that this will completely 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

Once the reset is complete, you need to login to your router using the default IP address, username, and password. You can find all of the information that you need in our WNDR3400v3 Login Guide.

Change Your Password

You need to change your router's default password after you log in for the first time. The factory default passwords for routers are very well known. If you need help coming up with a strong password, check out our Choosing a Strong Password guide.

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