This guide shows you how to reset your Nokia 5G21-12W-A router. This is not the same thing as rebooting a router. A reboot happens every time a router loses power. This is very different from a reset, which erases a router completely and returns it to factory default settings.

Warning: Since this erases everything you have done to the router, there are some things you need to consider first. The following settings in your router will be changed:

  • The router's login and password are reset.
  • Your WiFi name and password are reset.
  • Your ISP settings are reset, which means you will have to contact your ISP to get them back.
  • 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. Before you reset your router, you may want to try recovering your router password with our Router Password Finder.

There is usually a small reset button located on either the back or the bottom of a router. Most reset buttons look like this:

Router Reset Button

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 10 seconds and watch the lights. The blinking pattern of the lights on the front of the router should change when the reset is complete. Keep holding the button as long as you want, it will not hurt anything to hold it down too long.

Remember, this will totally reset your Nokia 5G21-12W-A 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.
