We will be discussing how to reset a Asus DSL-N55U router. This is not the same thing as rebooting a router. Rebooting a router consists of cycling the power by turning it off and back on again. A reset will literally reset the device. It erases everything you have ever done to this router and resets it to how it was from the factory.

Warning: Resetting the router should be your last resort. Lots of settings may be changed and it's a good idea to know what they are going to be before you reset your router. Take the following into consideration.

  • The router's main username and password will be reset to factory defaults.
  • The WiFi information such as SSID, password, and security mode are reset.
  • A DSL router will require you to re-enter the ISP (Internet Service Provider) username and password again so you can continue using the internet. If you are unsure of these details you need to call your ISP.
  • Any other settings you have changed since owning this router will be reset. Try to thing of everything you have done. This could be IP address changes, DNS servers, firewalls, port forwards etc.

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.

A reset needs to be done while the router is on. Do not unplug or turn off the router during the reset process as it could cause permanent damage to the router.

Now you need to locate the tiny reset button. This is typically found on the back panel of the device. We have circled it for you in the image below for your convenience.

This is the reset page from your Asus DSL-N55U router.

Using the tip of a sharp pencil or pin press and hold the reset button for about 10 seconds.

This will erase everything you have ever done to personalize this router. A reset should not be done until all other options have been exhausted.

Login to the Asus DSL-N55U

Now you need to login using the Asus DSL-N55U router's default username and password. This can be found in the manual and sometimes on the router itself. We have located them for you and included them in our Asus DSL-N55U Login Guide.

Change Your Password

After logging into the Asus DSL-N55U router it's a good idea to change this default password to something new. It doesn't really matter what you enter here so long as it's different. If creating new passwords is difficult we have created a Choosing a Strong Password guide for you.

Setup WiFi on the Asus DSL-N55U

The last setting we will talk about in this guide is the security settings for your WiFi. Some router companies like to leave the router security open as the default. This really means you have no security, it's open to everyone. We recommend changing this to WPA2-PSK. If you want more instructions on how to do this, check out our How to Setup WiFi on the Asus DSL-N55U.
