Reset the ZyXEL P-663HN-51 Frontier

This guide shows you how to reset your ZyXEL P-663HN-51 Frontier router. This is a much bigger deal than a router reboot. A reboot happens every time a router loses power. This is different from a reset because a reset completely erases all settings from the router.

Warning: Make sure that you fully understand the following before resetting your router. A router reset will affect the following settings:

• The router's login and password are reset.
• All WiFi login information and network names 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. 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.

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.

Recover Password in ZyXEL P-663HN-51 Frontier

Before you resort to doing a full router reset, you may want to try running our Router Password Finder first.

Router Password Finder can save you a ton of time by recovering your lost or forgotten router password instead of doing a full router reset.

Router Password Finder - Recover Lost or Forgotten Router Passwords

Only after you have tried to recover your missing router username and password should you perform a full router reset.

There is usually a small reset button located on either the back or the bottom of a router. Most reset buttons look like this:

Yours may look slightly different, but they are usually tiny. 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. You should notice that the blinking pattern of the lights on the front of the router changes after a few seconds. Do not worry about holding the button down too long; this is harmless.

Keep in mind that this will completely reset your ZyXEL P-663HN-51 Frontier 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 ZyXEL P-663HN-51 Frontier

After you are finished resetting your router, you need to login in using the original factory username and password. You can find all of the information that you need in our P-663HN-51 Frontier Login Guide.

Change Your Password

Do not forget to change your router's default password when you log back into it. Since factory passwords are well known, it's a huge security risk to leave your router set to the 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 note and tape it to the bottom of your router for future reference.
