This is the reset guide for the TP-Link TD-8840 router. This is a much bigger deal than a router reboot. Every time your router loses power it reboots. However, when you reset a router you, return it back to its factory default settings.

Warning: Since this erases everything you have done to the router, there are some things you need to consider first. The following settings will be changed in your router:

  • The router's login and password are reset.
  • All WiFi information such as network name, password, and authentication method are erased.
  • All ISP settings will reset to default, and you may have to contact your ISP.
  • All port forwards, firewall settings, and parental controls that you have configured will be removed.

A router reset is the last step you should take in recovering your router's password. 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.

Reset the TP-Link TD-8840

Usually there is a reset button located on the back or bottom of a router. Most reset buttons look like this:

Router Reset Button

Even though yours may look slightly different, you need to look for a tiny button. Sometimes the button is under a pinhole, and you need a paper clip to push it.

Watch the lights on the front of your router and hold the reset button down for about 10 seconds. You should notice that the blinking pattern of the lights on the front of the router changes after a few seconds. Do not be concerned about holding the reset button down too long. It will not hurt anything.

Remember, this will erase everything you have previously done to this TP-Link TD-8840 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-8840

After you are finished resetting your router, you need to login in using the original factory username and password. You can find all of the information that you need in our TD-8840 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. If you need help coming up with a strong password, check out our Choosing a Strong Password guide.

Tip: Put your new password on a post-in note and stick it to the bottom of your router.
