This guide shows you how to reset your Sagemcom Fast 5366 TN-A router to factory default settings. This is a much bigger deal than a router reboot. Rebooting a router is simply turning it off and back on again. 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. The following settings in your router will be changed:
- The router's login and password are reset to factory defaults.
- Your WiFi login, password, and network name are reset.
- Your ISP settings are reset, which means you will have to contact your ISP to get them back.
- All parental controls, firewall settings, and port forwards will be removed.
A router reset should be considered the last resort when you cannot log in to your router any other way. Before you reset your router you may want to try recovering your router password with our Router Password Finder.
