Understanding the hardware limitations of BCM63381B0-based devices will help you set realistic expectations. The chip integrates a 10/100 Ethernet switch, not Gigabit Ethernet. If you have internet speeds above 100 Mbps, this router will be a bottleneck regardless of firmware optimizations. The integrated USB 1.1 interface is also quite slow by modern standards — fine for basic printer sharing but not useful for high-speed storage access.
The firmware manages a dual-mode core that supports both VDSL2 (up to profile 17a) and ADSL2+ standards, allowing service providers to offer a single hardware platform for different copper-based services.
