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.

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.

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