With custom firmware, it can route near-gigabit speeds over VDSL2—something many Broadcom-based routers cannot. | Risk | Mitigation | | :--- |
UART is your friend. On the PCB (near the CPU), you'll find a 4-pin header:
Baud rate: 115200 8N1. Boot log reveals a treasure: U-Boot 1.1.4 (2009 vintage). If you own a D-Link DSL-224 (often stylized
Keeping your router’s firmware up to date is crucial for several reasons:
