Broadcom 3392 «CERTIFIED | 2026»

The Broadcom BCM3392 is a next-generation System-on-a-Chip (SoC) designed to push the boundaries of DOCSIS 3.1 technology. Often referred to in the industry as "DOCSIS 3.1+," "Extended DOCSIS 3.1," or "Ultra DOCSIS," this chipset provides a high-performance bridge for cable operators who want to offer multi-gigabit speeds without the immediate cost of a full DOCSIS 4.0 upgrade.

The BCM3392 arrived as the successor, designed to bridge the gap between standard cable and next-gen DOCSIS 4.0. Its "useful" innovation lies in its ability to support four OFDM channels. Cost: Expect retail modems with this chip to start at $350+

Introduction In the race for multi-gigabit home internet, the name on the box is usually Arris, Netgear, or Ubiquiti. But the name on the silicon is often Broadcom. The Broadcom BCM3392 (hypothetical model for this piece) represents the next generation of cable modem chipsets, designed to bridge the gap between current Gigabit plans and the emerging "10G" (10 Gigabit) cable infrastructure. No more firmware security patches for the core chip

The Fix: If you own a Broadcom 3392 device, open it up. If you see a tiny heatsink, replace it with a 25mm x 25mm copper heatsink and a thermal pad. Many users report a 15°C–20°C drop in temperature, extending the life of the router by years.
