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. Unplugging a router from the wall reboots it. However, when you reset a router you, return it back to its factory default settings.

Warning: Before you continue, there are a few things you need to know. The following settings in your router will be changed:

  • The router's username and password are reset.
  • All WiFi information such as network name, password, and authentication method are erased.
  • 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. 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.

Most routers have a small button on either the back or the bottom. Most reset buttons look like this:

Router Reset Button

Even though yours may look slightly different, you need to look for a tiny button. You might find a pinhole on the back of the router that requires a paper clip to push the button hidden under it.

Hold the reset button down for 10 seconds and watch the lights. Notice how the lights on the front of the router are blinking. When the lights do something different, the router is reset. It is harmless to hold the reset button too long.

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 follow the CGM4140COM Login Guide to find everything that you need to log in.

Change Your Password

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