This article covers how to reset the Technicolor CGM4140COM router back to factory default settings. This is not the same thing as rebooting a router. A reboot happens every time a router loses power. A Router Reset completely erases the router and returns it to factory 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.
  • Your WiFi name and password 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.

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.

On most routers you can find a small button on the back or the bottom labeled reset. What you are looking for is something that looks like this:

Router Reset Button

Your reset button may look different, but usually they are very small. Sometimes the button is under a pinhole, and you need a paper clip to push it.

Watch the front panel lights while you hold the reset button down for at least 10 seconds. Notice how the lights on the front of the router are blinking. When the lights do something different, the router is reset. Do not worry about holding the button down too long; this is harmless.

Just don't forget that this will totally reset your Technicolor CGM4140COM router.

Only do this once 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 CGM4140COM

Now that you have finished resetting your router, you need to log in using the default username and password from the factory. We have a CGM4140COM Login Guide with all this information ready for you.

Change Your Password

After logging in, you should really change your router's password for added security. 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: Put your new password on a post-in note and stick it to the bottom of your router.
