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.

Use a VPN
Have you considered using a VPN when you connect to the internet? A VPN is a great way to increase your security and anonymity while surfing.
We use and recommend NordVPN because not only is it the fastest VPN, it includes a new feature called Meshnet that makes securely sharing your home network super simple. With NordVPN Meshnet, you can connect to your devices from anywhere in the world, completely secure, over a highly encrypted VPN tunnel.
When shopping for a VPN, make sure that they meet the following criteria:
- Your VPN provider should have a no-logs policy. This means that they do not keep any logs of any kind.
- Make sure that your VPN provider has lots of exit nodes all around the world.
- Check that your VPN will not affect your speed.
- Verify that your VPN provider uses WireGuard as the underlying protocol.
- Many people prefer a VPN provider that is not based in the United States.
This is the list of requirements that we used when we were shopping around for a VPN provider. There are lots of free, shady VPN providers out there that we looked at and dismissed.
Based in Panama, using diskless servers, and with over 6,100 servers in 61 countries, we can safely say that NordVPN satisfies all of these requirements.
Once you've set up your NordVPN account on multiple computers and enabled Meshnet, you can seamlessly access all of your devices as if they were on the same network. You don't even have to log in to your router. It's very simple.
Every time you click on one of our affiliate links, such as NordVPN, we get a little kickback for introducing you to the service. Think of us as your VPN wingman.

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.
