This guide shows you how to reset your Technicolor CGM4140COM router to factory default settings. A router reset is very different 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: This is not a step to be taken lightly. When you reset your router, the following will happen.

  • The router's login and password are reset.
  • Your WiFi login, password, and network name 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.

Resetting your router should be considered the last step. 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.

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. What you are looking for is something that looks like this:

Router Reset Button

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

Watch the front panel lights while you hold the reset button down for at least 10 seconds. The lights on the front of the router should do something different when the reset happens. Do not be concerned about holding the reset button down too long. It will not hurt anything.

Remember, this will totally 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 you need to log in using the factory default username and password. 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. Leaving a router password set to default is a very serious security risk. If you need help coming up with a strong password, check out our Choosing a Strong Password guide.

Tip: Write your new password down on a post-it note and stick it to the bottom of your router.
