This guide shows you how to reset your Sagemcom Fast 3864V3HP router. This is not the same thing as rebooting a router. A reboot happens every time a router loses power. However, when you reset a router you, return it back to its factory default settings.
Warning: This is not a step to be taken lightly. When you reset your router, the following will happen.
- The router's username and password are reset to factory defaults.
- All WiFi login information and network names are reset.
- Your ISP username and password will be reset, and you may have to contact your ISP.
- Any firewall settings, parental controls, or port forwards 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. 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.
