In this article, you will learn how to reset your ZyXEL NR5103E back to factory settings. This is a much bigger deal than a router reboot. 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: Since this erases everything you have done to the router, there are some things you need to consider first. When you reset your router, the following will happen.
- The router's login and password are reset to factory defaults.
- All WiFi login information and network names are reset.
- Any ISP settings saved in your router will be removed. You may 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. Before you reset your router, you may want to try recovering your router password with our Router Password Finder.

Reset the ZyXEL NR5103E
Most routers have a small button on either the back or the bottom. Look at your router and try to find something that looks like this:
Yours may look slightly different, but they are usually tiny. Sometimes the reset button is under a pinhole on the back of the router, and you need a paper clip to push it.
Watch the front panel lights while you hold the reset button down for at least 10 seconds. The blinking pattern of the lights on the front of the router should change when the reset is complete. It is harmless to hold the reset button too long.
Just don't forget that this will totally reset your ZyXEL NR5103E router.
Only take this last step of fully resetting your router after you have exhausted all other troubleshooting options, such as running our Router Password Finder software, which can recover a lost router password for you.

Tip: Write your new password down on a post-it note and stick it to the bottom of your router.
