In this guide I will show you how to reset your Sagemcom Fast 3686 V3ch Com Hem router back to factory defaults. This is not the same thing as a reboot. When you reboot a router you are simply cycling the power to the device. A factory reset on the other hand erases all your previously configured settings and reverts them to factory defaults.
Warning: Resetting this router is a big step and should not be done unless you have exhausted all your other options first. Settings that will be changed are:
- The router's login username and password.
- The Internet protection username and password.
- If you have a DSL Internet connection you probably need the ISP (Internet Service Provider) username and password. Call your ISP for this info.
- Any other settings such as port forwards, IP address changes, etc...

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.
The first step in a reset is to know where the reset button is located. For the Sagemcom Fast 3686 V3ch Com Hem router you can find it on the back panel. We have circled the reset button for you in the image below:
Take a straightened paperclip or other sharp object and press down on the reset button for about 10 seconds. This starts the reset process which can sometimes take several minutes to finish.
Warning: DO NOT unplug or turn off the router during the reset process. Doing so can result in permanent damage to the unit.
Please remember a reset erases all your changes you have ever made to the router interface, a full reconfiguration needs to be done after you have finished.
Login to the Sagemcom Fast 3686 V3ch
Once the reset is complete you should login to the router's interface. To do this follow the directions on this Sagemcom Fast 3686 V3ch Com Hem Login Guide.
Change Your Password
Usually a router will encourage you to change the router's username and password. This is a very good idea as the router's login information is normally very insecure. For help creating a strong password for your router check out this Choosing a Strong Password guide.
Tip: To avoid losing this password in the future, write it down and attach it to the bottom of the router.
Setup WiFi for the Sagemcom Fast 3686 V3ch Com Hem Router
After you are logged in, check the wireless security by clicking Wi-Fi at the top and then choosing WiFi Settings in the left sidebar.
Make sure your router is using the security option of WPA2-PSK (AES). This is the strongest encryption available right now.
