This article covers how to reset the Arris VMDG505 router back to factory default settings. A router reset is very different than a router reboot. Every time your router loses power it reboots. 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. When you reset your router, the following will happen.

  • The router's username and password are reset.
  • 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.
  • All port forwards, firewall settings, and parental controls that you have configured will be removed.

Resetting your router should be considered the last step. Before you reset your router, you may want to try recovering your router password with our Router Password Finder.

Recover Password in Arris VMDG505

If you are resetting your router because you forgot your router password, then you should 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 - Lost or Forgotten Router Password Recovery Tool

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

Reset the Arris VMDG505

You can usually find a small reset button on either the back or the bottom of a router. Most reset buttons look like this:

Router Reset Button

Reset buttons are usually tiny. Yours may look slightly different than this. Sometimes the reset button is under a pinhole on the back of the router, and you need a paper clip to push it.

Hold the reset button down for 10 seconds and watch the lights. The blinking pattern of the lights on the front of the router should change when the reset is complete. Keep holding the button as long as you want, it will not hurt anything to hold it down too long.

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. You can follow the VMDG505 Login Guide to find everything that you need to log in.

Change Your Password

Be sure to change your router's default password after you get logged back in. Since factory passwords are well known, it's a huge security risk to leave your router set to the default. Our Choosing a Strong Password guide can help you pick a strong password for your router.

Tip: After creating this new password, we highly recommend writing this down on a post-it note and attaching it to the bottom of your router for future reference.
