## Summary description

StarTech USB-C to Dual Gigabit Ethernet Adapter (model US1GC301AU2R) provides two RJ-45 Gigabit ports and an additional USB Type-A port for wired connectivity. USB-powered with a maximum data transfer rate of 5000 Mbit/s, it supports simultaneous network connections for laptops or desktops with USB-C. Ideal for network redundancy, link aggregation, virtualization hosts, and environments needing multiple wired interfaces.

## Long description

The StarTech.com USB-C to Dual Gigabit Ethernet Adapter with USB (Type-A) Port adds wired network access to a laptop or desktop through a USB-C/Thunderbolt 3 port while also providing a USB 3.0 (Type-A) port for connecting legacy peripherals. The adapter offers two Gigabit Ethernet ports for reliable wired connections and is USB powered in a compact black enclosure.
Advantages
This adapter delivers full Gigabit network bandwidth by leveraging the 5 Gbps capability of USB 3.0 (USB 3.1 Gen 1), reducing transfer bottlenecks for large files and fast network access. It includes an integrated USB Type-A port so you can connect USB 3.0 devices while the adapter provides network access, and it is backward compatible with USB 2.0 systems. The adapter supports useful networking features such as Wake-on-LAN, VLAN tagging, Auto-MDIX, checksum offload and large send offload. Native driver support for Chrome OS and Windows 8.1 simplifies setup, and Mac OS X (10.10) is supported with driver installation.
Suitable for
Users who need reliable wired Gigabit connections on laptops or desktops with USB-C/Thunderbolt 3 ports
Environments where connecting two separate Ethernet networks or redundant links is required
Users who need to connect USB Type-A peripherals while using a single USB-C port for networking
When it may not be suitable
This adapter requires a host device with a USB-C or Thunderbolt 3 physical port; it is not suitable for systems that lack those ports. While the adapter supports Mac OS X with driver installation, native driver support is provided for Chrome OS and Windows 8.1, so macOS users may need to install drivers before use.

Host interface: USB Type-C connector (supports USB 3.0/USB 3.1 Gen 1 speeds)
Additional port: 1 × USB 3.0 (Type-A)

How to use
Plug the adapter into the USB-C or Thunderbolt 3 port on your computer, connect Ethernet cables to the two RJ-45 ports and, if needed, plug a USB Type-A device into the integrated USB 3.0 port. On Chrome OS and Windows 8.1 the adapter should be recognised using native drivers; on macOS (10.10) follow the manufacturer's instructions to install the required driver. After connection, configure network settings in the host operating system as required.
What to consider before purchase
Ensure your computer has a USB-C or Thunderbolt 3 port
Check operating system compatibility and whether driver installation is required for macOS
Confirm that two Gigabit Ethernet ports meet your networking or redundancy needs
Usage recommendations
For best performance, connect the adapter to a USB 3.0/3.1 Gen 1-capable USB-C port and use CAT5e or better Ethernet cabling. If using macOS, install the provided driver before initial connection to ensure full functionality.
