Recommendations

Place the docking station on a stable, flat surface near your laptop and router for easy cable routing. Use the USB 3.2 Gen 1 ports for high-bandwidth peripherals (external SSDs, webcams) and reserve USB 2.0 ports for keyboards, mice or low-speed accessories. For optimal network performance, use a quality Cat5e or Cat6 Ethernet cable and avoid long, damaged cables. If the system requests drivers after first connection, follow the laptop manufacturer's guidance to install the correct OneLink+ or docking drivers.
