The Startech.com USB-C to Gigabit Ethernet Adapter (model US1GC30W) is a compact network adapter that provides a Gigabit Ethernet port via a USB Type-C connection. It enables a wired network connection for laptops, desktops, and other devices with a USB-C interface, particularly for models such as MacBook or Chromebook Pixel. The adapter supports Gigabit networks with data rates up to 1000 Mbit/s via an RJ45 port and is powered directly through the USB connection, eliminating the need for an external power source.

Applications

The adapter is suitable for both mobile and stationary applications where a stable, wired network connection is required. It is especially suited for users who wish to avoid Wi-Fi or require higher bandwidth and lower latency. Compatibility with Thunderbolt 3 and Thunderbolt 4 extends its use to devices supporting these interfaces. Its portable design, weighing 24 g and measuring 210 mm in length, makes it ideal for on-the-go use, such as during travel or in daily office environments.

Features and Specifications in Detail

The adapter includes an integrated USB Type-C plug and an RJ45 port for Ethernet connectivity. It supports network standards IEEE 802.3, IEEE 802.3u, IEEE 802.3ab, and IEEE 802.3az, and enables automatic network configuration detection (Auto MDIX). The full-duplex connection allows simultaneous data transmission in both directions. Support for Jumbo Frames up to 9000 bytes improves efficiency when transferring large data volumes. Additionally, Wake-on-LAN is implemented to enable device activation over the network. VLAN Tagging is supported, which is relevant for networks with separated traffic classes.

Technology Explained Simply

The adapter uses the Realtek RTL8153 chipset, which provides native driver support. This means no additional software installation is required once the device is connected. Data transfer occurs via USB 3.2 Gen 1 (also known as USB 3.1 Gen 1), enabling a maximum transfer rate of 5000 Mbit/s. The Ethernet connection operates at speed levels of 10, 100, and 1000 Mbit/s, with the actual speed depending on the network. Power is supplied through the USB connection, eliminating the need for an external power source. The housing is made of plastic and is white in colour.

Compatibility and Accessories

The adapter is compatible with a wide range of operating systems, including Windows 7 to Windows 11 (including x64 and Server editions), macOS from version 10.7 (up to 15.0), and Linux distributions with kernel 4.11 and higher (LTS versions). Native driver support also includes Chrome OS. Compatibility with Thunderbolt 3 and Thunderbolt 4 expands its usability to corresponding devices.

Installation and Mounting

Installation is plug-and-play: simply insert the adapter into the USB-C port of the device, and the network connection is established automatically. No additional software or driver installation is required. The reversible design of the USB-C plug allows for easy and error-free connection regardless of orientation. The integrated cable connection (length 145 mm) ensures a stable connection without requiring additional cable extensions.

Operational Advantages

The adapter provides a reliable, wired network connection with Gigabit speed, particularly beneficial for large file transfers or stable connections. Native driver support reduces setup time. Powering via USB and its low weight make it especially suitable for mobile use. Support for Jumbo Frames and VLAN Tagging extends its applications in professional networks. The operating temperature ranges from 0 to 70 °C, and the relative humidity during operation is 5 to 90 %.
