This guide shows you how to reset your Technicolor CGM4140COM 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. This is different from a reset because a reset completely erases all settings from the router.

Warning: Proceed with caution; resetting your router can be a major headache. The following settings in your router will be changed:

  • The router's username and password are reset to factory defaults.
  • Your WiFi name and password are reset.
  • If your router has any ISP settings they will be removed, and you will have to contact your ISP.
  • Any port forwards, firewall settings, or parental controls that you have configured will be removed.

A router reset is the last step you should take in recovering your router's password. Before you reset your router, you may want to try recovering your router password with our Router Password Finder.

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.

NordVPN is the fastest VPN!

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.

Usually there is a reset button located on the back or bottom of a router. This is what a typical reset button looks like:

Router Reset Button

Yours may look slightly different, but they are usually tiny. You may need a paper clip to push the reset button.

Hold the reset button down for 10 seconds and watch the lights. After a few seconds the lights should blink differently. When this happens, the reset is complete. Do not worry about holding the button down too long; this is harmless.

Keep in mind that this will completely reset your Technicolor CGM4140COM router.

This last step should only be taken if you have tried everything else, such as using our Router Password Finder software, which can recover lost or forgotten router passwords.

Login to the Technicolor CGM4140COM

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 CGM4140COM Login Guide.

Change Your Password

You need to change your router's default password after you log in for the first time. Since factory passwords are well known, it's a huge security risk to leave your router set to the default. You can follow our Choosing a Strong Password guide to help you pick a solid password for your router.

Tip: A great place to write your new password down is on a piece of paper taped to the bottom of your router.
