In this article, you will learn how to reset your Sagemcom Fast 5866T back to factory settings. A router reset is a much bigger deal than a router reboot. Unplugging a router from the wall reboots it. This is different from a reset because a reset completely erases all settings from the router.
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.
- Your WiFi name and password are reset.
- If your router has any ISP settings they will be removed, and you will have to contact your ISP.
- All port forwards, firewall settings, and parental controls that you have configured will be removed.
A router reset should be considered the last resort when you cannot log in to your router any other way. Make sure that you have tried to recover your router password using our Router Password Finder first.
