This article covers how to reset the TP-Link TL-WR840N v3 router back to factory default settings. This is not the same thing as rebooting a router. Turning a router off and back on again causes a reboot. A Router Reset completely erases the router and returns it to factory settings.
Warning: This is not a step to be taken lightly. When you reset your router, the following will happen.
- The router's login and password are reset to factory defaults.
- All WiFi settings are reset, including network name and password.
- Your ISP username and password will be reset, and you may have to contact your ISP.
- All parental controls, firewall settings, and port forwards will be removed.
A router reset should be considered the last resort when you cannot log in to your router any other way. Before you reset your router you may want to try recovering your router password with our Router Password Finder.

Use a VPN
Have you considered using a VPN when you connect to the internet? A VPN is a great way to increase your security and anonymity while surfing.
We use and recommend NordVPN because not only is it the fastest VPN, it includes a new feature called Meshnet that makes securely sharing your home network super simple. 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.
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.

There is usually a small reset button located on either the back or the bottom of a router. Most reset buttons look like this:
Yours may look slightly different, but they are usually tiny. You may need a paper clip to push the reset button.
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. You can hold the button down as long as you like, it will not hurt anything.
Keep in mind that this will completely reset your TP-Link TL-WR840N v3 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.
