In this article, you will learn how to reset your ZyXEL ZyWALL ATP100 back to factory settings. Resetting a router is different than rebooting a router. Rebooting a router is simply turning it off and back on again. A Router Reset completely erases the router and returns it to factory settings.
Warning: Before you continue, there are a few things you need to know. The following settings in your router will be changed:
- The router's login and password are reset to factory defaults.
- All WiFi settings are reset, including network name and password.
- If your router has any ISP settings they will be removed, and you will have to contact your ISP.
- Any firewall settings, parental controls, and port forwards that you have configured will be removed.
Resetting your router should be considered the last step. 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 ZyWALL ATP100
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
A router reset should be the last thing you try if you are unable to login.
Reset the ZyXEL ZyWALL ATP100
Most routers have a small button on either the back or the bottom. A typical reset button looks like this:
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.
Keep an eye on the lights on the front of your router while holding the reset button down for about 10 seconds. The blinking pattern of the lights on the front of the router should change when the reset is complete. You cannot hold the button too long, and it will not hurt the router to hold the reset button down for longer than 10 seconds.
Keep in mind that this will completely reset your ZyXEL ZyWALL ATP100 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 ZyWALL ATP100
After you are finished resetting your router, you need to login in using the original factory username and password. Just follow our ZyWALL ATP100 Login Guide to find all of the information that you need.
Change Your Password
Do not forget to change your router's default password when you log back into it. It's a very bad idea to leave your router's password set to the factory default. You can follow our Choosing a Strong Password guide to help you pick a solid password for your router.
Tip: Write your new password down on a post-it note and stick it to the bottom of your router.
