This guide shows you how to reset your Netcomm 3G21WB router. A router reset is very different than a router reboot. A reboot happens every time a router loses power. Resetting a router erases all settings from it and returns it to factory defaults.

Warning: Make sure that you fully understand the following before resetting your router. When you reset your router, the following will happen.

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

Resetting your router should be considered the last step. 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.

There is usually 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

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. 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.

Keep in mind that this will completely reset your Netcomm 3G21WB 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 Netcomm 3G21WB

Now that you have finished resetting your router, you need to log in using the default username and password from the factory. Our 3G21WB Login Guide has all of the information that you need.

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. Our Choosing a Strong Password guide can help you pick a strong password for your router.

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