This article covers how to reset the Sagemcom Fast 3890v3 router back to factory default settings. A router reset is a much bigger deal than a router reboot. A reboot happens every time a router loses power. This is very different from a reset, which erases a router completely and returns it to factory default 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 to factory defaults.
- All WiFi login information and network names are reset.
- If your router has any ISP settings they will be removed, and you will have to contact your ISP.
- All parental controls, firewall settings, and port forwards will be removed.
Resetting your router should be considered the last step. Make sure that you have tried to recover your router password using our Router Password Finder first.

Recover Password in Sagemcom Fast 3890v3
Instead of resetting your router back to factory settings, you may want to try running our Router Password Finder first.
Our Router Password Finder can recover your lost or forgotten router password without doing a full router reset, which can save you lots of time.
Router Password Finder - Recover Lost or Forgotten Router Passwords
If you are unable to recover your lost router password, then you may have to proceed with a full router reset.
Reset the Sagemcom Fast 3890v3
There is usually a small reset button located 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. You may need a paper clip to push the reset button.
Hold the reset button down for 10 seconds and watch the lights. Notice how the lights on the front of the router are blinking. When the lights do something different, the router is reset. 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.
Remember, this will totally reset your Sagemcom Fast 3890v3 router.
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 3890v3
After you are finished resetting your router, you need to login in using the original factory username and password. Just follow our Fast 3890v3 Login Guide to find 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. It is a huge security risk to leave your router's password set to the factory default. You can follow our Choosing a Strong Password guide to help you pick a solid 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.
