This article covers how to reset the Technicolor C2100T router back to factory default settings. A router reset is very different than a router reboot. Turning a router off and back on again causes a reboot. Resetting a router erases all settings from it and returns it to factory defaults.
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 to factory defaults.
- All WiFi settings are reset, including network name and password.
- Your ISP settings are reset, which means you will have to contact your ISP to get them back.
- 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.

Just keep in mind that a router reset should be done as the last resort when you are unable to login to your router.
Reset the Technicolor C2100T
There is usually a small reset button located on either the back or the bottom of a router. Look for something that looks like this:
Yours may look slightly different, but they are usually tiny. If you find a pinhole on the back of the router then that may be the reset button. You will need a paper clip to push 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. You cannot hold the button too long, and it will not hurt the router to hold the reset button down for longer than 10 seconds.
Just don't forget that this will totally reset your Technicolor C2100T 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 C2100T
After you are finished resetting your router, you need to login in using the original factory username and password. We have a C2100T Login Guide with all this information ready for you.
Change Your Password
Be sure to change your router's default password after you get logged back in. The factory default passwords for routers are very well known. If you need help coming up with a strong password, check out our Choosing a Strong Password guide.
Tip: Put your new password on a post-in note and stick it to the bottom of your router.
