If you need to reset your Arris VMDG505 router back to factory settings, then this article shows you how. A router reset is very different 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: Proceed with caution; resetting your router can be a major headache. A router reset will affect the following settings:

  • The router's username and password are reset to factory defaults.
  • All WiFi information such as network name, password, and authentication method are erased.
  • If your router has any ISP settings they will be removed, and you will have to contact your ISP.
  • Any port forwards, firewall settings, or parental controls 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. You should be sure that you have tried to at least recover your router password using our Router Password Finder before resorting to a router reset.

A router reset should be the last thing you try if you are unable to login.

Reset the Arris VMDG505

Most of the time you can find a small reset button located on either the back or the bottom of a router. This is what a typical reset button looks like:

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 lights on the front of your router and hold the reset button down for about 10 seconds. The blinking pattern of the lights on the front of the router should change when the reset is complete. You can hold the button down as long as you like, it will not hurt anything.

Just don't forget that 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

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

Change Your Password

You need to change your router's default password after you log in for the first time. 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 post-it note and stick it to the bottom of your router.
