is primarily a (Gigabit Passive Optical Network) gateway, not natively EPON. While some modified versions or "XPON" firmwares exist to allow it to work on EPON networks, the device is designed as a Wi-Fi 5 dual-band ONT for high-speed fiber services. 🚀 Key Specifications

This is the protocol ISPs use to remotely manage the device. The firmware contains the ACS (Auto Configuration Server) URL and credentials. If this is corrupted, the ISP cannot remotely provision the device, requiring a truck roll (technician visit).

Older firmware versions are notorious for random 2.4GHz and 5GHz band steering drops and channel interference issues.
