This article covers how to reset the Asus RT-AC1900P router back to factory default settings. A router reset is very different than a router reboot. 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 will be changed in your router:

  • The router's login credentials are reset.
  • All WiFi information such as network name, password, and authentication method are erased.
  • If your router has any ISP settings they will be removed, and you will have to contact your ISP.
  • Any port forwards, firewall settings, or parental controls that you have configured 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.

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 is the fastest VPN!

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.

On most routers you can find a small button on the back or the bottom labeled reset. Most reset buttons look like this:

Router Reset Button

Reset buttons are usually tiny. Yours may look slightly different than this. You might find a pinhole on the back of the router that requires a paper clip to push the button hidden under it.

Keep an eye on the lights on the front of your router while holding the reset button down for about 10 seconds. The blinking pattern of the lights on the front of the router should change when the reset is complete. You can hold the button down as long as you like, it will not hurt anything.

Keep in mind that this will completely reset your Asus RT-AC1900P 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 Asus RT-AC1900P

Now that you have finished resetting the router, you need to login to the router interface using the default username and password. You can follow the RT-AC1900P Login Guide to find everything that you need to log in.

Change Your Password

Do not forget to change your router's default password when you log back into it. It's a very bad idea to leave your router's password set to the factory default. If you need help coming up with a strong password, check out our Choosing a Strong Password guide.

Tip: After creating this new password, we highly recommend writing this down on a post-it note and attaching it to the bottom of your router for future reference.
