This is the reset guide for the Technicolor CGM4140COM router. A router reset is a much bigger deal than a router reboot. A reboot happens every time a router loses power. This is different from a reset because a reset completely erases all settings from the router.

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 login 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, and port forwards that you have configured will be removed.

A router reset is the last step you should take in recovering your router's password. 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.

Reset the Technicolor CGM4140COM

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

Even though yours may look slightly different, you need to look for a tiny button. Sometimes the reset button is under a pinhole on the back of the router, and you need a paper clip to push it.

Keep an eye on the lights on the front of your router while holding the reset button down for about 10 seconds. The blinking pattern of the lights on the front of the router should change when the reset is complete. Keep holding the button as long as you want, it will not hurt anything to hold it down too long.

Keep in mind that this will completely 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 you need to log in using the factory default username and password. We have a CGM4140COM Login Guide with all this information ready for you.

Change Your Password

You need to change your router's default password after you log in for the first time. It is a huge security risk to leave your router's password set to the factory default. Our Choosing a Strong Password guide can help you pick a strong password for your router.

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