This article covers how to reset the ZyXEL P 660H T1 router back to factory default settings. A router reset is a much bigger deal than a router reboot. Unplugging a router from the wall reboots it. Resetting a router erases all settings from it and returns it to factory defaults.

Warning: Since this erases everything you have done to the router, there are some things you need to consider first. A router reset will affect the following settings:

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

Since a router reset is such a drastic step, it should only be done as a last resort when you cannot recover your router's password using any other methods. Make sure that you have tried to recover your router password using our Router Password Finder first.

Recover Password in ZyXEL P 660H T1

If the only reason that you are resetting your router is because you forgot your router password, then you may want to try running our Router Password Finder instead of resetting your router.

Our Router Password Finder can recover your lost or forgotten router password without doing a full router reset, which can save you lots of time.

Router Password Finder - Automatically 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.

Reset the ZyXEL P 660H T1

On most routers you can find a small button on the back or the bottom labeled reset. This is what a typical reset button looks like:

Router Reset Button

Your reset button may look different, but usually they are very small. You might find a pinhole on the back of the router that requires a paper clip to push the button hidden under it.

Hold the reset button down for about 10 seconds while watching the lights on the front of your router. The blinking pattern of the lights on the front of the router should change when the reset is complete. Keep holding the button as long as you want, it will not hurt anything to hold it down too long.

Just don't forget that this will totally reset your ZyXEL P 660H T1 router.

Be sure to only reset your router if you have tried everything else, such as running our Router Password Finder software, which can find your lost or forgotten router password for you.

Login to the ZyXEL P 660H T1

Now that you have finished resetting the router, you need to login to the router interface using the default username and password. We have a P 660H T1 Login Guide with all this information ready for you.

Change Your Password

You need to change your router's default password after you log in for the first time. 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 talks about choosing 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.
