In this article, you will learn how to reset your Sagemcom Fast 3686 back to factory settings. A router reset is very different than a router reboot. Turning a router off and back on again causes a reboot. A Router Reset completely erases the router and returns it to factory settings.

Warning: Before you proceed, there are a few things you need to know. When you reset your router, the following will happen.

  • The router's login credentials are reset to factory defaults.
  • All WiFi information such as network name, password, and authentication method are erased.
  • Your ISP settings are reset, which means you will have to contact your ISP to get them back.
  • Any parental controls, firewall settings, or port forwards 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.

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 lights on the front of the router should do something different when the reset happens. Do not be concerned about holding the reset button down too long. It will not hurt anything.

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.

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 talks about choosing a strong password for your router.

Tip: After creating this new password, we highly recommend writing this down on a post-it note and attaching it to the bottom of your router for future reference.
