If you need to reset your Sagemcom Fast 3686 router back to factory settings, then this article shows you how. A router reset is very different than a router reboot. A reboot happens every time a router loses power. 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 will be changed in your router:
- The router's login and password are reset to factory defaults.
- All WiFi settings are reset, including network name and password.
- Your ISP settings are reset, which means you will have to contact your ISP to get them back.
- Any port forwards, firewall settings, or parental controls 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
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.

You can usually find a small reset button on either the back or the bottom of a router. This is what a typical reset button looks like:
Even though yours may look slightly different, you need to look for a tiny button. You may need a paper clip to push the reset button.
Keep an eye on the lights on the front of your router while holding 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. Do not be concerned about holding the reset button down too long. It will not hurt anything.

Be sure to only reset your router if you have tried everything else, such as running our Router Password Finder software, which can find your lost or forgotten router password for you.
