You can't recover a forgotten admin password without a factory reset, which wipes your settings. Sorry.
If you need to reset:
- Locate the recessed Reset button on the back of the Orbi router, near the power connector.
- With the router on, use a paperclip to press and hold the Reset button.
- Keep holding for at least 10 seconds until the Power LED blinks amber. Then release.
- The router reboots and restores factory defaults. This takes about two minutes.
After the reset:
- The WiFi name and password revert to the ones on the product label.
- The admin password reverts to the one you specified during initial setup, or the default if you never changed it.
- You must set up your Internet connection again.
If that didn't work—like the router doesn't respond—ensure you're holding the button down long enough. A quick press just reboots it; a long press (10+ seconds) is needed for factory reset.
Write your new password down somewhere safe this time.
