This guide shows you how to reset your ZyXEL NR5103E router to factory default settings. This is a much bigger deal than a router reboot. Unplugging a router from the wall reboots it. 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 username and password are reset.
  • All WiFi settings are reset, including network name and password.
  • Your ISP username and password will be reset, and you may have to contact your ISP.
  • 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. Make sure that you have tried to recover your router password using our Router Password Finder first.

Use a VPN

Have you considered using a VPN when you connect to the internet? A VPN is a great way to increase your security and anonymity while surfing.

We use and recommend NordVPN because not only is it the fastest VPN, it includes a new feature called Meshnet that makes securely sharing your home network super simple. With NordVPN Meshnet, you can connect to your devices from anywhere in the world, completely secure, over a highly encrypted VPN tunnel.

When shopping for a VPN, make sure that they meet the following criteria:

  • Your VPN provider should have a no-logs policy. This means that they do not keep any logs of any kind.
  • Make sure that your VPN provider has lots of exit nodes all around the world.
  • Check that your VPN will not affect your speed.
  • Verify that your VPN provider uses WireGuard as the underlying protocol.
  • Many people prefer a VPN provider that is not based in the United States.

This is the list of requirements that we used when we were shopping around for a VPN provider. There are lots of free, shady VPN providers out there that we looked at and dismissed.

Based in Panama, using diskless servers, and with over 6,100 servers in 61 countries, we can safely say that NordVPN satisfies all of these requirements.

Once you've set up your NordVPN account on multiple computers and enabled Meshnet, you can seamlessly access all of your devices as if they were on the same network. You don't even have to log in to your router. It's very simple.

Every time you click on one of our affiliate links, such as NordVPN, we get a little kickback for introducing you to the service. Think of us as your VPN wingman.

Usually there is a reset button located on the back or bottom of a router. This is what a typical reset button looks like:

Router Reset Button

Reset buttons are usually tiny. Yours may look slightly different than this. Sometimes the button is under a pinhole, and you need a paper clip to push it.

Hold the reset button down for 10 seconds and watch the lights. You should notice that the blinking pattern of the lights on the front of the router changes after a few seconds. Do not worry about holding the button down too long; this is harmless.

Just don't forget that this will totally reset your ZyXEL NR5103E router.

Only do this once you have exhausted all other troubleshooting options, such as running our Router Password Finder software, which can recover a lost router password for you.

Login to the ZyXEL NR5103E

After you are finished resetting your router, you need to login in using the original factory username and password. We have a NR5103E Login Guide with all this information ready for you.

Change Your Password

Be sure to change your router's default password after you get logged back in. Since factory passwords are well known, it's a huge security risk to leave your router set to the 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.
