This article covers how to reset the Sagemcom Fast 3686 router back to factory default settings. This is a much bigger deal 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: Before you continue, there are a few things you need to know. The following settings in your router will be changed:
- 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.
- All parental controls, firewall settings, and port forwards will be removed.
Resetting your router should be considered the last step. Before you reset your router, you may want to try recovering your router password with our Router Password Finder.

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. What you are looking for is something that 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.
Keep an eye on the lights on the front of your router while holding the reset button down for about 10 seconds. After a few seconds the lights should blink differently. When this happens, the reset is complete. 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.
Don't forget, this step will totally reset your Sagemcom Fast 3686 router back to factory settings.
Only take this last step of fully resetting your router after 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 3686
Now that you have finished resetting the router, you need to login to the router interface using the default username and password. You can follow the Fast 3686 Login Guide to find everything that you need to log in.
Change Your Password
Do not forget to change your router's default password when you log back into it. The factory default passwords for routers are very well known. Our Choosing a Strong Password guide talks about choosing a strong password for your router.
Tip: After creating this new password, we highly recommend writing this down on a post-it note and attaching it to the bottom of your router for future reference.
