This guide shows you how to reset your Arris VMDG505 router to factory default settings. This is not the same thing as rebooting a router. Rebooting a router is simply turning it off and back on again. Resetting a router erases all settings from it and returns it to factory defaults.

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 credentials are reset to factory defaults.
  • All WiFi information such as network name, password, and authentication method are erased.
  • All ISP settings will reset to default, and you may have to contact your ISP.
  • Any parental controls, firewall settings, or port forwards will be removed.

A router reset is the last step you should take in recovering your router's password. 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 faster than ever 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.

Recover Password in Arris VMDG505

Before you resort to doing a full router reset, you may want to try running our Router Password Finder first.

Router Password Finder can save you a ton of time by recovering your lost or forgotten router password instead of doing a full router reset.

Router Password Finder - Automatically Recover Lost or Forgotten Router Passwords

If you are unable to recover your lost router password, then you may have to proceed with a full router reset.

On most routers you can find a small button on the back or the bottom labeled reset. Look for something that looks like this:

Router Reset Button

Even though yours may look slightly different, you need to look for a tiny button. 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 lights on the front of your router and hold the reset button down for about 10 seconds. Notice how the lights on the front of the router are blinking. When the lights do something different, the router is reset. It is harmless to hold the reset button too long.

Remember, this will totally reset your Arris VMDG505 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.

Login to the Arris VMDG505

Once the reset is complete, you need to login to your router using the default IP address, username, and password. We have a VMDG505 Login Guide with all this information ready for you.

Change Your Password

After logging in, you should really change your router's password for added security. It's a very bad idea to leave your router's password set to the factory default. Our Choosing a Strong Password guide can help you pick a strong password for your router.

Tip: Put your new password on a post-in note and stick it to the bottom of your router.
