This is the reset guide for the Sagemcom Fast 4315U router. A router reset is very different than a router reboot. Rebooting a router is simply turning it off and back on again. 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. When you reset your router, the following will happen.
- The router's login credentials are reset to factory defaults.
- 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.
- 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. Before you reset your router you may want to try recovering your router password with our Router Password Finder.

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.
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.

You can usually find a small reset button on either the back or the bottom of a router. Look for something that looks like this:
Reset buttons are usually tiny. Yours may look slightly different than this. You may need a paper clip to push the reset button.
Watch the lights on the front of your router and hold the reset button down for about 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.
