If you need to reset your Sagemcom Fast 3864V3AC router back to factory settings, then this article shows you how. A router reset is very different than a router reboot. Rebooting a router is simply turning it off and back on again. This is different from a reset because a reset completely erases all settings from the router.
Warning: Make sure that you fully understand the following before resetting your router. The following settings will be changed in your router:
- The router's username and password are reset.
- 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, and 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.

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. Most reset buttons look like this:
Reset buttons are usually tiny. Yours may look slightly different than this. Sometimes the reset button is under a pinhole on the back of the router, and you need a paper clip to push it.
Watch the lights on the front of your router and hold the reset button down for about 10 seconds. After a few seconds the lights should blink differently. When this happens, the reset is complete. Keep holding the button as long as you want, it will not hurt anything to hold it down too long.
Remember, this will erase everything you have previously done to this Sagemcom Fast 3864V3AC router.
This last step should only be taken if you have tried everything else, such as using our Router Password Finder software, which can recover lost or forgotten router passwords.
