This guide shows you how to reset your Sagemcom Fast 5366 LTE-A router. A router reset is very different than a router reboot. Turning a router off and back on again causes a reboot. This is different from a reset because a reset completely erases all settings from the router.
Warning: Before you continue, there are a few things you need to know. A router reset will affect the following settings:
- The router's username and password are reset to factory defaults.
- Your WiFi login, password, and network name are reset.
- Your ISP username and password will be reset, and you may have to contact your ISP.
- All port forwards, firewall settings, and parental controls that you have configured will be removed.
Since a router reset is such a drastic step, it should only be done as a last resort when you cannot recover your router's password using any other methods. 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.

Use a VPN Instead
Have you considered using a VPN instead of forwarding a port? For most users, a VPN is a much simpler and more secure choice than forwarding a port.
We use and recommend NordVPN because not only is it the fastest VPN, it includes a new feature called Meshnet that makes forwarding a port no longer necessary for most applications. 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.

You can usually find a small reset button on either the back or the bottom of a router. A typical reset button looks like this:
Your reset button may look different, but usually they are very small. Sometimes the reset button is under a pinhole on the back of the router, and you need a paper clip to push it.
Hold the reset button down for about 10 seconds while watching the lights on the front of your router. You should notice that the blinking pattern of the lights on the front of the router changes after a few seconds. Keep holding the button as long as you want, it will not hurt anything to hold it down too long.
