This guide shows you how to reset your ZyXEL VMG3925-B10C router. This is a much bigger deal than a router reboot. Turning a router off and back on again causes a reboot. 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. A router reset will affect the following settings:
- The router's username and password are reset.
- Your WiFi name and password are reset.
- Your ISP settings are reset, which means you will have to contact your ISP to get them back.
- 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. 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.
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.

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. The lights on the front of the router should do something different when the reset happens. Do not worry about holding the button down too long; this is harmless.
Remember, this will erase everything you have previously done to this ZyXEL VMG3925-B10C router.
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 ZyXEL VMG3925-B10C
Once the reset is complete, you need to login to your router using the default IP address, username, and password. Our VMG3925-B10C Login Guide has 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. 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.
