In this guide I will show you how to reset the Asus RT-AC55U router. This is not the same thing as a reboot. When you reboot a router you are only cycling the power to the device. A reset takes all the settings and reverts them all to the default settings.

Warning: Resetting a router is a big step. All your previously configured settings are erased. Settings that change are:

  • The router's username and password.
  • The WiFi username and password.
  • If you use DSL, you may need to re-enter the ISP (Internet Service Provider) username and password. Call your ISP for these details.
  • All changes you have made in your router such as: IP addresses, schedules, port forwards, DNS settings...

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.

The first step in a reset is to find the reset button on the outside of the device. We have found it for you and circled it in the image below:

This is the reset page from your Asus RT-AC55U router.

Using an unfolded paperclip or pin press down on the reset button for about 5 seconds. This should begin the reset process for the Asus RT-AC55U router.

Warning: Do not unplug or turn off the router during this reset process. Doing so will likely cause permanent damage to the unit.

Please remember a reset erases every setting you have ever changed in the past. We strongly recommend exhausting your other troubleshooting methods first.

Login to the Asus RT-AC55U

After the reset is complete and the Asus RT-AC55U router has turned itself back on, you need to login to the interface using the factory defaults. Follow the directions on our Asus RT-AC55U Login Guide.

Change Your Password

Most routers urge you to change the username and password immediately. This is because the username and password are typically very insecure. To help create a new password read the instructions on our Choosing a Strong Password page.

Tip: One way to avoid losing this password is to write it down on a slip of paper and attach it to the bottom of the router for future reference.

Setup the Asus RT-AC55U Wifi

Don't forget to check on the router's wireless settings before you exit the router interface. Make sure you are using the latest encryption to keep your network safe. We recommend using WPA2 Personal with AES and create your own strong WiFi password.

Unfortunately we do not have the WiFi screenshots to create a WiFi guide. We need your help. If you own this router please find out how you can help us by clicking this link to learn more.
