If you need to reset your SFR neufbox-NB4-SER-r2 router back to factory settings, then this article shows you how. A router reset 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: Make sure that you fully understand the following before resetting your router. When you reset your router, the following will happen.

  • The router's login credentials are reset.
  • All WiFi information such as network name, password, and authentication method are erased.
  • All ISP settings will reset to default, and you may have to contact your ISP.
  • Any firewall settings, parental controls, and port forwards 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. Before you reset your router, you may want to try recovering your router password with our Router Password Finder.

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.

NordVPN is the fastest VPN!

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 at your router and try to find something that looks like this:

Router Reset Button

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.

Hold the reset button down for 10 seconds and watch the lights. You should notice that the blinking pattern of the lights on the front of the router changes after a few seconds. It is harmless to hold the reset button too long.

Don't forget, this step will totally reset your SFR neufbox-NB4-SER-r2 router back to factory settings.

This last step should only be taken if you have tried everything else, such as using our Router Password Finder software, which can recover lost or forgotten router passwords.

Login to the SFR neufbox-NB4-SER-r2

Once the reset is complete, you need to login to your router using the default IP address, username, and password. Just follow our neufbox-NB4-SER-r2 Login Guide to find all of the information that you need.

Change Your Password

You need to change your router's default password after you log in for the first time. Since factory passwords are well known, it's a huge security risk to leave your router set to the default. If you need help coming up with a strong password, check out our Choosing a Strong Password guide.

Tip: Write your new password down on a post-it note and stick it to the bottom of your router.
