If you need to reset your Sagemcom Fast 3864V3HP router back to factory settings, then this article shows you how. Resetting a router is different than rebooting a router. Rebooting a router is simply turning it off and back on again. However, when you reset a router you, return it back to its factory default settings.

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.
  • All WiFi login information and network names are reset.
  • All ISP settings will reset to default, and you may have to contact your ISP.
  • All port forwards, firewall settings, and parental controls that you have configured will be removed.

Since a router reset is such a drastic step, it should only be done as a last resort when you cannot recover your router's password using any other methods. Make sure that you have tried to recover your router password using our Router Password Finder first.

Reset buttons are usually tiny. Yours may look slightly different than this. 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.

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. It is harmless to hold the reset button too long.
