This is the reset guide for the ZTE ZXDSL 831CII router. Resetting a router is different than rebooting a router. Rebooting a router is simply turning it off and back on again. Resetting a router erases all settings from it and returns it to factory defaults.

Warning: Since this erases everything you have done to the router, there are some things you need to consider first. A router reset will affect the following settings:

  • The router's login and password are reset.
  • Your WiFi name and password are reset.
  • Your ISP username and password will be reset, and you may have to contact your ISP.
  • Any firewall settings, parental controls, and port forwards 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. Make sure that you have tried to recover your router password using our Router Password Finder first.

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. Most reset buttons look like this:

Router Reset Button

Reset buttons are usually tiny. Yours may look slightly different than this. You may need a paper clip to push the reset button.

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. It is harmless to hold the reset button too long.

Don't forget, this step will totally reset your ZTE ZXDSL 831CII router back to factory settings.

Be sure to only reset your router if you have tried everything else, such as running our Router Password Finder software, which can find your lost or forgotten router password for you.

Login to the ZTE ZXDSL 831CII

Now you need to log in using the factory default username and password. You can find all of the information that you need in our ZXDSL 831CII Login Guide.

Change Your Password

Be sure to change your router's default password after you get logged back in. It's a very bad idea to leave your router's password set to the factory default. Our Choosing a Strong Password guide can help you pick a strong 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.
