In this article, you will learn how to reset your TP-Link TL-ER5120 back to factory settings. A router reset is a much bigger deal than a router reboot. A reboot happens every time a router loses power. However, when you reset a router you, return it back to its factory default settings.
Warning: Before you continue, there are a few things you need to know. The following settings in your router will be changed:
- The router's login and password are reset to factory defaults.
- Your WiFi name and password are reset.
- All ISP settings will reset to default, and you may have to contact your ISP.
- Any firewall settings, parental controls, and port forwards that you have configured 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 TP-Link TL-ER5120
Most of the time you can find a small reset button located on either the back or the bottom of a router. Look at your router and try to find something that looks like this:
Reset buttons are usually tiny. Yours may look slightly different than this. You might find a pinhole on the back of the router that requires a paper clip to push the button hidden under it.
Watch the front panel lights while you hold the reset button down for at least 10 seconds. The lights on the front of the router should do something different when the reset happens. Do not be concerned about holding the reset button down too long. It will not hurt anything.
Don't forget, this step will totally reset your TP-Link TL-ER5120 router back to factory settings.
