Firmware is the low‑level software that controls how the router’s hardware behaves. It’s not an application you can delete or replace; it’s the core code that determines how the device boots, how it processes network traffic, how it handles security protocols, and how its various components—GPON interface, Ethernet ports, Wi‑Fi radios, USB ports, and VoIP functions—interact with each other and with your ISP’s infrastructure.

Automatically switches your devices between the 2.4 GHz and 5 GHz bands based on distance and signal strength. Log into the web gateway, navigate to Wi-Fi
