This guide shows you how to reset your TP-Link TD-8840T router to factory default settings. A router reset is very different than a router reboot. Rebooting a router is simply turning it off and back on again. This is different from a reset because a reset completely erases all settings from the router.
Warning: Proceed with caution; resetting your router can be a major headache. A router reset will affect the following settings:
- The router's login credentials are reset to factory defaults.
- All WiFi login information and network names are reset.
- All ISP settings will reset to default, 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.
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:
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.
Keep an eye on the lights on the front of your router while holding the reset button down for about 10 seconds. The lights on the front of the router should do something different when the reset happens. Keep holding the button as long as you want, it will not hurt anything to hold it down too long.
Remember, this will erase everything you have previously done to this TP-Link TD-8840T router.
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 TP-Link TD-8840T
Once the reset is complete, you need to login to your router using the default IP address, username, and password. You can find all of the information that you need in our TD-8840T Login Guide.
Change Your Password
After logging in, you should really change your router's password for added security. Since factory passwords are well known, it's a huge security risk to leave your router set to the default. 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 post-it note and stick it to the bottom of your router.
