This guide shows you how to reset your Technicolor TG789vac v3 router to factory default settings. Resetting a router is different than rebooting a router. Rebooting a router is simply turning it off and back on again. Resetting a router erases all settings from it and returns it to factory defaults.

Warning: This is not a step to be taken lightly. A router reset will affect the following settings:

  • The router's login credentials are reset to factory defaults.
  • Your WiFi login, password, and network name are reset.
  • Your ISP username and password will be reset, and you may have to contact your ISP.
  • Any port forwards, firewall settings, or parental controls that you have configured 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.

Reset the Technicolor TG789vac v3

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

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

Hold the reset button down for about 10 seconds while watching the lights on the front of your router. The lights on the front of the router should do something different when the reset happens. Keep holding the button as long as you want, it will not hurt anything to hold it down too long.

Don't forget, this step will totally reset your Technicolor TG789vac v3 router back to factory settings.

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 TG789vac v3

After you are finished resetting your router, you need to login in using the original factory username and password. You can follow the TG789vac v3 Login Guide to find everything that you need to log in.

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