This is the reset guide for the Sagemcom Fast 3686 DNA router. This is a much bigger deal than a router reboot. Unplugging a router from the wall reboots it. A Router Reset completely erases the router and returns it to factory settings.
Warning: This is not a step to be taken lightly. When you reset your router, the following will happen.
- The router's login credentials are reset.
- 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.
- Any port forwards, firewall settings, or parental controls that you have configured will be removed.
Resetting your router should be considered the last step. 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. Look for something that looks like this:
Even though yours may look slightly different, you need to look for a tiny button. If you find a pinhole on the back of the router then that may be the reset button. You will 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. The blinking pattern of the lights on the front of the router should change when the reset is complete. Do not worry about holding the button down too long; this is harmless.
Remember, this will erase everything you have previously done to this Sagemcom Fast 3686 DNA router.
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.
Login to the Sagemcom Fast 3686 DNA
Now that you have finished resetting the router, you need to login to the router interface using the default username and password. Our Fast 3686 DNA Login Guide has all of the information that you need.
Change Your Password
After logging in to your router for the first time, you need to change your router's password. Since factory passwords are well known, it's a huge security risk to leave your router set to the default. Our Choosing a Strong Password guide can help you pick a strong password for your router.
Tip: Write your new password down on a post-it note and stick it to the bottom of your router.
