If you need to reset your ZyXEL P 660HW T1 router back to factory settings, then this article shows you how. A router reset is very different than a router reboot. A reboot happens every time a router loses power. A Router Reset completely erases the router and returns it to factory settings.

Warning: Proceed with caution; resetting your router can be a major headache. The following settings will be changed in your router:

  • The router's login credentials are reset.
  • All WiFi settings are reset, including network name and password.
  • Your ISP settings are reset, which means you will have to contact your ISP to get them back.
  • Any parental controls, firewall settings, or port forwards will be removed.

A router reset should be considered the last resort when you cannot log in to your router any other way. You should be sure that you have tried to at least recover your router password using our Router Password Finder before resorting to a router reset.

Recover Password in ZyXEL P 660HW T1

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 - Lost or Forgotten Router Password Recovery Tool

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

Reset the ZyXEL P 660HW T1

Most of the time you can find a small reset button located on either the back or the bottom of a router. A typical reset button looks like this:

Router Reset Button

Yours may look slightly different, but they are usually tiny. If you find a pinhole on the back of the router then that may be the reset button. You will need a paper clip to push it.

Hold the reset button down for 10 seconds and watch the lights. After a few seconds the lights should blink differently. When this happens, the reset is complete. Do not worry about holding the button down too long; this is harmless.

Remember, this will erase everything you have previously done to this ZyXEL P 660HW T1 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 ZyXEL P 660HW T1

After you are finished resetting your router, you need to login in using the original factory username and password. Our P 660HW T1 Login Guide has all of the information that you need.

Change Your Password

Be sure to change your router's default password after you get logged back in. It's a very bad idea to leave your router's password set to the factory default. Our Choosing a Strong Password guide talks about choosing a strong password for your router.

Tip: A great place to write your new password down is on a piece of paper taped to the bottom of your router.
