If you need to reset your Arris VMDG505 router back to factory settings, then this article shows you how. This is not the same thing as rebooting a router. Turning a router off and back on again causes a reboot. This is different from a reset because a reset completely erases all settings from the router.

Warning: Before you continue, there are a few things you need to know. The following settings will be changed in your router:

  • The router's login and password are reset to factory defaults.
  • All WiFi settings are reset, including network name and password.
  • Your ISP settings are reset, which means you will have to contact your ISP to get them back.
  • All parental controls, firewall settings, and port forwards will be removed.

Resetting your router should be considered the last step. Make sure that you have tried to recover your router password using our Router Password Finder first.

Recover Password in Arris VMDG505

Instead of resetting your router back to factory settings, 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

Do not do a full router reset until after you have tried every other option to log in to your router.

Reset the Arris VMDG505

Most routers have a small button on either the back or the bottom. Most reset buttons look 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. After a few seconds the lights should blink differently. When this happens, the reset is complete. Do not worry about holding the button down too long; this is harmless.

Don't forget, this step will totally reset your Arris VMDG505 router back to factory settings.

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 VMDG505

Now that you have finished resetting the router, you need to login to the router interface using the default username and password. You can find all of the information that you need in our VMDG505 Login Guide.

Change Your Password

Be sure to change your router's default password after you get logged back in. It is a huge security risk 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: Write your new password down on a post-it note and stick it to the bottom of your router.
