/wʌn ˈtuː ˈzɪərəʊ ˈrɛsɛt/
noun — “the magic button for network devices that clears the slate like it never existed.”
120 Reset refers to a factory or hard reset process used in networking and telecommunications equipment, often specific to routers, modems, or other managed devices. Triggering a 120 Reset restores the device to its original factory settings, erasing all custom configurations, passwords, IP settings, and stored data. This is useful when troubleshooting persistent issues, recovering from misconfigurations, or preparing a device for reassignment.
The process is typically initiated via hardware buttons, web interfaces, or command-line interfaces like Command Line Interface. While powerful, a 120 Reset is irreversible, meaning any misconfigured network rules, saved Environment Variables, or security settings will be lost unless previously backed up. Many devices warn users about this action to prevent accidental data loss.
120 Reset is often used in combination with network recovery or device management strategies, such as Device Management, to restore consistent operational behavior. IT administrators may perform it after firmware updates, network migrations, or when troubleshooting connectivity or performance issues. Integrating reset procedures with Configuration Management helps ensure devices are reconfigured automatically after the reset, minimizing downtime.
Conceptually, a 120 Reset is like hitting the “undo all” button on your digital life — everything goes back to square one, and you can start fresh without lingering mistakes.
120 Reset is like telling your network device, “Forget everything you know… you’re a blank slate now.”
