In this article, you will learn how to reset your Siemens Gigaset SE551 back to factory settings. A router reset is a much bigger deal than a router reboot. Every time your router loses power it reboots. This is very different from a reset, which erases a router completely and returns it to factory default settings.

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 credentials are reset to factory defaults.
  • All WiFi information such as network name, password, and authentication method are erased.
  • Any ISP settings saved in your router will be removed. You may have to contact your ISP.
  • Any parental controls, firewall settings, or port forwards will be removed.

Since a router reset is such a drastic step, it should only be done as a last resort when you cannot recover your router's password using any other methods. 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 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.

Most routers have a small button on either the back or the bottom. A typical reset button looks like this:

Router Reset Button

Yours may look slightly different, but they are usually tiny. Sometimes the reset button is under a pinhole on the back of the router, and you need a paper clip to push it.

Hold the reset button down for 10 seconds and watch the lights. After a few seconds the lights should blink differently. When this happens, the reset is complete. Do not worry about holding the button down too long; this is harmless.

Don't forget, this step will totally reset your Siemens Gigaset SE551 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 Siemens Gigaset SE551

Once the reset is complete, you need to login to your router using the default IP address, username, and password. Just follow our Gigaset SE551 Login Guide to find all of the information that you need.

Change Your Password

Do not forget to change your router's default password when you log back into it. It is a huge security risk to leave your router's password set to the factory default. If you need help coming up with a strong password, check out our Choosing a Strong Password guide.

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