Users can use three different methods to restore a UniFi Security Gateway (USG) to its factory default settings. Either with the hard reset (reset button on the device), the soft reset (via the UniFi Controller), or via SSH.

ATTENTION: Do not disconnect the device during the reset process. Resetting your device will wipe out all history and configurations and it will disappear from the controller. You will need to adopt it once again.
