The Broadcom BCM3392 (often shortened to “Broadcom 3392”) is a system-on-chip (SoC) designed primarily for home networking and broadband gateway devices (modems, residential gateways, and managed consumer routers). It integrates CPU cores, network packet acceleration, fixed-function hardware blocks, and I/O interfaces to handle routing, NAT, Wi‑Fi backhaul, and related broadband tasks with low power and high throughput.
One reason the Broadcom 3392 enjoys a long life is third-party firmware support. broadcom 3392
Broadcom is notoriously closed-source with their wireless drivers, which makes open-source support difficult. However, the 3392 is old enough that the community has reverse-engineered or obtained binary blobs to make it work. As a successor to earlier DOCSIS 3
The Broadcom BCM3392 is a high-performance DOCSIS 3.1 cable modem chipsets designed for the next generation of high-speed broadband internet. As a successor to earlier DOCSIS 3.0 and initial 3.1 silicon, the BCM3392 enables cable modems and gateways to deliver multi-gigabit speeds to residential and business customers, utilizing existing hybrid fiber-coaxial (HFC) infrastructure. competitive online gaming
It is a critical component in the transition toward "Ultra-High Definition" streaming, competitive online gaming, and smart home connectivity, supporting the industry's push toward 10G broadband networks.
