This is the reset guide for the Sagemcom Fast 3864AC router. Resetting a router is different than rebooting a router. Every time your router loses power it reboots. This is very different from a reset, which erases a router completely and returns it to factory default settings.
Warning: Proceed with caution; resetting your router can be a major headache. A router reset will affect the following settings:
- The router's login and password are reset to factory defaults.
- Your WiFi name and password are reset.
- All ISP settings will reset to default, 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. Make sure that you have tried to recover your router password using our Router Password Finder first.
