This is the reset guide for the Trendnet TDM-C400 router. This is a much bigger deal than a router reboot. A reboot happens every time a router loses power. 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. When you reset your router, the following will happen.

  • The router's username and password 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.
  • All port forwards, firewall settings, and parental controls that you have configured will be removed.

Resetting your router should be considered the last step. 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 faster than ever deal!

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 of the time you can find a small reset button located on either the back or the bottom of a router. This is what a typical reset button looks like:

Router Reset Button

Your reset button may look different, but usually they are very small. 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 about 10 seconds while watching the lights on the front of your router. The blinking pattern of the lights on the front of the router should change when the reset is complete. Do not be concerned about holding the reset button down too long. It will not hurt anything.

Just don't forget that this will totally reset your Trendnet TDM-C400 router.

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 Trendnet TDM-C400

Now that you have finished resetting the router, you need to login to the router interface using the default username and password. You can follow the TDM-C400 Login Guide to find everything that you need to log in.

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. Our Choosing a Strong Password guide talks about choosing a strong 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.
