Adaptador de rede USB Gigabit LevelOne, hub USB

The LevelOne USB-0503 Ethernet Adapter is a compact USB 3.0 combo adapter that provides a 10/100/1000 Mbps RJ-45 Ethernet port and a 3‑port SuperSpeed USB 3.0 hub. It enables wired network connectivity and additional USB peripheral connections for laptops and desktops that lack a built‑in Ethernet port.

Advantages

The adapter supports wire‑speed 10/100/1000 Mbps transmission and reception and is USB 3.0/2.0/1.0 compliant for broad host compatibility. Installation is plug-and-play for most systems, and the device includes a built‑in Wake-on‑LAN feature for remote startup of connected computers. It is compatible with Windows and macOS platforms and integrates a three‑port SuperSpeed USB hub for connecting peripherals.

Suitable for

• MacBook and ultrabook users who need a wired Ethernet connection
• Laptops and desktops without a built‑in Ethernet port
• Users who require fast local network file transfers or stable wired internet access
• Connecting USB peripherals (external drives, cameras, printers) while using a single USB port

How to use

Connect the adapter to an available USB port on your computer. Plug an Ethernet cable into the RJ-45 port to establish a wired network connection. Attach any USB peripherals to the three USB 3.0 ports as needed. Most modern operating systems will detect the adapter automatically; if required, install drivers provided by the OS or from the manufacturer's support site to enable full functionality including Wake-on‑LAN.

Recommendations

For optimal performance, use a USB 3.0 port on the host device and a Category 5e or higher Ethernet cable to achieve Gigabit speeds. Ensure the latest drivers or OS updates are installed and enable Wake‑on‑LAN in the system BIOS/UEFI and operating system settings if remote startup is required.
