If you need to reset your Buffalo WHR-1166DHP4 router back to factory settings, then this article shows you how. Resetting a router is different than rebooting a router. Every time your router loses power it reboots. This is different from a reset because a reset completely erases all settings from the router.
Warning: Make sure that you fully understand the following before resetting your router. The following settings in your router will be changed:
- 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.
- 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. 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.

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.

Usually there is a reset button located on the back or bottom of a router. Look for something that looks like this:
Reset buttons are usually tiny. Yours may look slightly different than this. Sometimes the button is under a pinhole, and you need a paper clip to push it.
Hold the reset button down for 10 seconds and watch the lights. After a few seconds the lights should blink differently. When this happens, the reset is complete. It is harmless to hold the reset button too long.
Just don't forget that this will totally reset your Buffalo WHR-1166DHP4 router.
