This is the reset guide for the Arris DG3450A router. This is a much bigger deal than a router reboot. Rebooting a router is simply turning it off and back on again. A Router Reset completely erases the router and returns it to factory settings.

Warning: Make sure that you fully understand the following before resetting your router. A router reset will affect the following settings:

  • The router's username and password are reset to factory defaults.
  • All WiFi settings are reset, including network name and password.
  • Any ISP settings saved in your router will be removed. You may have to contact your ISP.
  • Any port forwards, firewall settings, or 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. Before you reset your router, you may want to try recovering your router password with our Router Password Finder.

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.

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.

Keep an eye on the lights on the front of your router while holding the reset button down for about 10 seconds. 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.

Remember, this will erase everything you have previously done to this Arris DG3450A 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 Arris DG3450A

Now you need to log in using the factory default username and password. You can find all of the information that you need in our DG3450A Login Guide.

Change Your Password

You need to change your router's default password after you log in for the first time. It's a very bad idea to leave your router's password set to the factory 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 note and tape it to the bottom of your router for future reference.
