This guide shows you how to reset your Mercusys Halo S12 router. Resetting a router is different than rebooting a router. Every time your router loses power it reboots. A Router Reset completely erases the router and returns it to factory settings.
Warning: Since this erases everything you have done to the router, there are some things you need to consider first. The following settings in your router will be changed:
- The router's login and password are reset to factory defaults.
- All WiFi settings are reset, including network name and password.
- Any ISP settings saved in your router will be removed. You may have to contact your ISP.
- All port forwards, firewall settings, and parental controls that you have configured 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. 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.
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.

On most routers you can find a small button on the back or the bottom labeled reset. Most reset buttons look like this:
Your reset button may look different, but usually they are very small. Sometimes the button is under a pinhole, and you need a paper clip to push it.
Watch the front panel lights while you hold the reset button down for at least 10 seconds. You should notice that the blinking pattern of the lights on the front of the router changes after a few seconds. 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 erase everything you have previously done to this Mercusys Halo S12 router.
Only do this once 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 Mercusys Halo S12
Now that you have finished resetting the router, you need to login to the router interface using the default username and password. Just follow our Halo S12 Login Guide to find all of the information that you need.
Change Your Password
Be sure to change your router's default password after you get logged back in. Leaving a router password set to default is a very serious security risk. You can follow our Choosing a Strong Password guide to help you pick a solid password for your router.
Tip: Write your new password down on a note and tape it to the bottom of your router for future reference.
