In this article, you will learn how to reset your ZyXEL O2 GateWay back to factory settings. Resetting a router is different than rebooting a router. Unplugging a router from the wall reboots it. However, when you reset a router you, return it back to its factory default settings.
Warning: Before you continue, there are a few things you need to know. The following settings will be changed in your router:
- The router's username and password are reset.
- Your WiFi login, password, and network name are reset.
- Any ISP settings saved in your router will be removed. You may have to contact your ISP.
- 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.

Even though yours may look slightly different, you need to look for a tiny button. You may need a paper clip to push the reset button.
Hold the reset button down for about 10 seconds while watching the lights on the front of your router. You should notice that the blinking pattern of the lights on the front of the router changes after a few seconds. Keep holding the button as long as you want, it will not hurt anything to hold it down too long.
