This guide shows you how to reset your Sagemcom Fast 3890v3 router. Resetting a router is different than rebooting a router. A reboot happens every time a router loses power. However, when you reset a router you, return it back to its factory default settings.

Warning: Proceed with caution; resetting your router can be a major headache. The following settings will be changed in your router:

  • The router's username and password are reset to factory defaults.
  • All WiFi login information and network names 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.

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.

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

Yours may look slightly different, but they are usually tiny. You might find a pinhole on the back of the router that requires a paper clip to push the button hidden under it.

Keep an eye on the lights on the front of your router while holding the reset button down for about 10 seconds. You should notice that the blinking pattern of the lights on the front of the router changes after a few seconds. You can hold the button down as long as you like, it will not hurt anything.

Just don't forget that this will totally reset your Sagemcom Fast 3890v3 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.
