Fiberhome Sr120-a Firmware

The SR120-A is an entry-level to mid-range gateway designed for residential users.

Wireless: Usually supports Wi-Fi 4 (802.11n) 2x2 MIMO, though later hardware revisions may include Wi-Fi 5 (802.11ac). It typically operates on dual bands (2.4GHz / 5GHz).

Processor: Realtek or Broadcom chipset (common in Fiberhome CPEs), typically running at 400MHz–600MHz for this tier.

Flash/RAM: Standard configuration is often 16MB Flash / 64MB RAM (sufficient for routing but limited for heavy third-party firmware).

If the stock firmware is too buggy or limited (e.g., the Wi-Fi keeps dropping), flashing custom firmware is risky. A better investment for a stable network is: fiberhome sr120-a firmware
