This guide shows you how to reset your Sagemcom Fast 5366SD router. This is a much bigger deal than a router reboot. Every time your router loses power it reboots. A Router Reset completely erases the router and returns it to factory settings.
Warning: Make sure that you fully understand the following before resetting your router. The following settings in your router will be changed:
- The router's login credentials are reset.
- All WiFi login information and network names are reset.
- Any ISP settings saved in your router will be removed. You may have to contact your ISP.
- 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. Make sure that you have tried to recover your router password using our Router Password Finder first.

Reset the Sagemcom Fast 5366SD
Most routers have a small button on either the back or the bottom. A typical reset button looks like this:
Yours may look slightly different, but they are usually tiny. If you find a pinhole on the back of the router then that may be the reset button. You will need a paper clip to push it.
Watch the front panel lights while you hold the reset button down for at least 10 seconds. Notice how the lights on the front of the router are blinking. When the lights do something different, the router is reset. You cannot hold the button too long, and it will not hurt the router to hold the reset button down for longer than 10 seconds.
Remember, this will erase everything you have previously done to this Sagemcom Fast 5366SD router.
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.
Login to the Sagemcom Fast 5366SD
Now you need to log in using the factory default username and password. You can follow the Fast 5366SD Login Guide to find everything that you need to log in.
Change Your Password
After logging in to your router for the first time, you need to change your router's password. Since factory passwords are well known, it's a huge security risk to leave your router set to the default. If you need help coming up with a strong password, check out our Choosing a Strong Password guide.
Tip: A great place to write your new password down is on a piece of paper taped to the bottom of your router.
