How can I restart the mobile router(FWA505) so the password on the label works again?

Zyxel_JoyLee

To restore your Zyxel mobile router to its factory default settings so that the default login password printed on the label works again, you must perform a Factory Reset rather than a standard reboot.

You can accomplish this using the physical reset button or by managing its registration status if it is connected to Nebula:

Option 1: Hardware Factory Reset (never registered on the Nebula)

1. Ensure the mobile router is powered on.
2. Locate the RESET pinhole (typically found on the bottom or back of the device near the ports).
3. Insert a paperclip or a SIM card ejector tool into the pinhole.
4. Press and hold the RESET button for at least 10 seconds.
5. Release the button once you see the Power LED start blinking.
6. Allow 2–3 minutes for the router to complete the reboot cycle.
7. Once fully booted, you can connect to its Wi-Fi or LAN port and use the admin username and default password printed on the device sticker.

Option 2: Considerations for Nebula-Managed Devices

If your mobile router was previously registered on the Nebula Control Center (NCC), Nebula automatically overrides the local admin password with a central site-wide password. To prevent this from blocking you:

1. Disconnect from the Internet: Keep the cellular or ethernet WAN disconnected during the reset and initial login. This stops the device from automatically downloading its Nebula configurations before you can log in locally.
2. Remove from Nebula (if no longer using cloud management):
   • Log into your Nebula Control Center account.
   • Go to Organization-wide > License & Inventory > Devices.
   • Select your mobile router and click on Actions > Remove from organization.
   • After removal, perform the physical hardware reset (Option 1). It will permanently revert to standalone mode, allowing you to use the label credentials.
