If you need to reset your Technicolor EPC3940ADL router back to factory settings, then this article shows you how. A router reset is very different 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: Make sure that you fully understand the following before resetting your router. The following settings will be changed in your router:

  • The router's login and password are reset.
  • Your WiFi name and password are reset.
  • All ISP settings will reset to default, and you may have to contact your ISP.
  • Any parental controls, firewall settings, or port forwards will be removed.

Since a router reset is such a drastic step, it should only be done as a last resort when you cannot recover your router's password using any other methods. Make sure that you have tried to recover your router password using our Router Password Finder first.

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.

NordVPN birthday deal!

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.

On most routers you can find a small button on the back or the bottom labeled reset. This is what a typical reset button looks like:

Router Reset Button

Reset buttons are usually tiny. Yours may look slightly different than this. Sometimes the reset button is under a pinhole on the back of the router, and you need a paper clip to push it.

Hold the reset button down for 10 seconds and watch the lights. You should notice that the blinking pattern of the lights on the front of the router changes after a few seconds. You can hold the button down as long as you like, it will not hurt anything.

Remember, this will erase everything you have previously done to this Technicolor EPC3940ADL 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 Technicolor EPC3940ADL

Once the reset is complete, you need to login to your router using the default IP address, username, and password. You can follow the EPC3940ADL Login Guide to find everything that you need to log in.

Change Your Password

Be sure to change your router's default password after you get logged back in. Leaving a router password set to default is a very serious security risk. Our Choosing a Strong Password guide talks about choosing a strong password for your router.

Tip: Write your new password down on a note and tape it to the bottom of your router for future reference.
