This is the reset guide for the ZyXEL NBG-4604 router. Resetting a router is different than rebooting a router. Unplugging a router from the wall reboots it. A Router Reset completely erases the router and returns it to factory settings.
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 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.
- All parental controls, firewall settings, and port forwards will be removed.
A router reset is the last step you should take in recovering your router's password. 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.

Reset the ZyXEL NBG-4604
Most of the time you can find a small reset button located on either the back or the bottom of a router. This is what a typical reset button looks like:

Even though yours may look slightly different, you need to look for a tiny button. 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.
Watch the lights on the front of your router and hold 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 can hold the button down as long as you like, it will not hurt anything.
Keep in mind that this will completely reset your ZyXEL NBG-4604 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 NBG-4604
Once the reset is complete, you need to login to your router using the default IP address, username, and password. You can find all of the information that you need in our NBG-4604 Login Guide.
Change Your Password
You need to change your router's default password after you log in for the first time. It's a very bad idea to leave your router's password set to the factory default. If you need help coming up with a strong password, check out our Choosing a Strong Password guide.
Tip: Write your new password down on a post-it note and stick it to the bottom of your router.
