Enhanced Performance: Delivers up to 5 Gbps data transfer speeds, offering a 400% increase over standard Gigabit Ethernet.
Optimal Setup: To achieve 5Gbps speeds, use a CAT6 or higher Ethernet cable and ensure your device's USB port supports USB 3.2 Gen 2 (10Gbps) or higher.
Efficient Power Management: The RTL8157 chipset reduces power consumption and heat generation, ensuring stable performance during extended use.
Thermal Design: Features an aluminum casing with integrated heat dissipation holes to maintain optimal operating temperatures.
Auto Mode Switching: Automatically switches to Lite mode at 2.5Gbps or 5Gbps speeds to prevent overheating.
Plug and Play: Supports macOS 15 and above without the need for additional drivers.
Driver Installation Required: For Windows 11 and Linux Kernel 5.17, drivers are needed, which can be easily installed using the provided instructions.
Device Compatibility: Compatible with devices featuring USB 3.2 Gen 2 (10Gbps) or higher ports.
Apple M-Series Compatibility: Only compatible with Apple devices equipped with M3 chips or newer; not compatible with M1 or M2 chips.
Avoiding Interference: For optimal performance, connect the adapter directly to the device's USB port, avoiding the use of USB hubs, extension cables, or docking stations.
