In this article, you will learn how to reset your Thomson Alcatel ACG905 back to factory settings. This is not the same thing as rebooting a router. Unplugging a router from the wall reboots it. Resetting a router erases all settings from it and returns it to factory defaults.

Warning: Proceed with caution; resetting your router can be a major headache. A router reset will affect the following settings:

  • The router's login and password are reset.
  • 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.
  • Any firewall settings, parental controls, or port forwards that you have configured will be removed.

A router reset should be considered the last resort when you cannot log in to your router any other way. 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.

NordVPN is the fastest VPN!

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. A typical reset button looks like this:

Router Reset Button

Your reset button may look different, but usually they are very small. Sometimes the button is under a pinhole, and you need a paper clip to push it.

Watch the front panel lights while you hold the reset button down for at least 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.

Remember, this will totally reset your Thomson Alcatel ACG905 router.

This last step should only be taken if you have tried everything else, such as using our Router Password Finder software, which can recover lost or forgotten router passwords.

Login to the Thomson Alcatel ACG905

Now you need to log in using the factory default username and password. You can follow the ACG905 Login Guide to find everything that you need to log in.

Change Your Password

After logging in to your router for the first time, you need to change your router's password. It's a very bad idea 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: A great place to write your new password down is on a piece of paper taped to the bottom of your router.
