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.

Use a VPN Instead
Have you considered using a VPN instead of forwarding a port? For most users, a VPN is a much simpler and more secure choice than forwarding a port.
We use and recommend NordVPN because not only is it the fastest VPN, it includes a new feature called Meshnet that makes forwarding a port no longer necessary for most applications. 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. 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.
Login to the Tecom AH4021
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.
Change Your Password
Do not forget to change your router's default password when you log back into it. The factory default passwords for routers are very well known. If you need help coming up with a strong password, check out our Choosing a Strong Password guide.
Tip: Put your new password on a post-in note and stick it to the bottom of your router.
