This is the reset guide for the Arris VMDG505 router. This is a much bigger deal than a router reboot. A reboot happens every time a router loses power. Resetting a router erases all settings from it and returns it to factory defaults.

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

  • 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.
  • Any firewall settings, parental controls, and port forwards that you have configured will be removed.

Since a router reset is such a drastic step, it should only be done as a last resort when you cannot recover your router's password using any other methods. 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.

NordVPN birthday deal!

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.

You can usually find a small reset button on either the back or the bottom of a router. What you are looking for is something that looks like this:

Router Reset Button

Yours may look slightly different, but they are usually tiny. You might find a pinhole on the back of the router that requires a paper clip to push the button hidden under 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 erase everything you have previously done to this Arris VMDG505 router.

Only do this once you have exhausted all other troubleshooting options, such as running our Router Password Finder software, which can recover a lost router password for you.

Login to the Arris VMDG505

Now that you have finished resetting the router, you need to login to the router interface using the default username and password. Our VMDG505 Login Guide has all of the information that you need.

Change Your Password

Do not forget to change your router's default password when you log back into it. Leaving a router password set to default is a very serious security risk. Our Choosing a Strong Password guide can help you pick a strong 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.
