This guide shows you how to reset your Technicolor EPC3940ADL router to factory default settings. This is a much bigger deal than a router reboot. Every time your router loses power it reboots. This is very different from a reset, which erases a router completely and returns it to factory default settings.

Warning: Make sure that you fully understand the following before resetting your router. A router reset will affect the following settings:

  • The router's username and password are reset to factory defaults.
  • All WiFi information such as network name, password, and authentication method are erased.
  • Your ISP settings are reset, which means you will have to contact your ISP to get them back.
  • All parental controls, firewall settings, and 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. 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.

Recover Password in Technicolor EPC3940ADL

Before you resort to doing a full router reset, you may want to try running our Router Password Finder first.

Router Password Finder is designed from the ground up to help you recover your forgotten router username and password, which can save you a lot of time.

Router Password Finder - Automatically Recover Lost or Forgotten Router Passwords

If you are unable to recover your lost router password, then you may have to proceed with a full router reset.

Reset the Technicolor EPC3940ADL

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:

Router Reset Button

Your reset button may look different, but usually they are very small. You might find a pinhole on the back of the router that requires a paper clip to push the button hidden under it.

Keep an eye on the lights on the front of your router while holding the reset button down for about 10 seconds. You should notice that the blinking pattern of the lights on the front of the router changes after a few seconds. You cannot hold the button too long, and it will not hurt the router to hold the reset button down for longer than 10 seconds.

Don't forget, this step will totally reset your Technicolor EPC3940ADL router back to factory settings.

Be sure to only reset your router if you have tried everything else, such as running our Router Password Finder software, which can find your lost or forgotten router password for you.

Login to the Technicolor EPC3940ADL

Now that you have finished resetting your router, you need to log in using the default username and password from the factory. You can find all of the information that you need in our EPC3940ADL Login Guide.

Change Your Password

After logging in to your router for the first time, you need to change your router's password. Since factory passwords are well known, it's a huge security risk to leave your router set to the default. Our Choosing a Strong Password guide talks about choosing a strong password for your router.

Tip: After creating this new password, we highly recommend writing this down on a post-it note and attaching it to the bottom of your router for future reference.
