This guide shows you how to reset your Tecom AH4021 router to factory default settings. This is a much bigger deal than a router reboot. Turning a router off and back on again causes a reboot. However, when you reset a router you, return it back to its factory default settings.
Warning: Proceed with caution; resetting your router can be a major headache. When you reset your router, the following will happen.
- The router's login and password are reset to factory defaults.
- Your WiFi login, password, and network name are reset.
- Your ISP username and password will be reset, and you may have to contact your ISP.
- Any firewall settings, parental controls, or port forwards that you have configured will be removed.
Resetting your router should be considered the last step. Make sure that you have tried to recover your router password using our Router Password Finder first.

Reset the Tecom AH4021
There is usually a small reset button located on either the back or the bottom of a router. A typical reset button looks like this:
Reset buttons are usually tiny. Yours may look slightly different than this. If you find a pinhole on the back of the router then that may be the reset button. You will need a paper clip to push it.
Hold the reset button down for about 10 seconds while watching the lights on the front of your router. The blinking pattern of the lights on the front of the router should change when the reset is complete. Do not be concerned about holding the reset button down too long. It will not hurt anything.
Keep in mind that this will completely reset your Tecom AH4021 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.

Once the reset is complete, you need to login to your router using the default IP address, username, and password. We have a AH4021 Login Guide with all this information ready for you.
