Product information

Description

The StarTech USB-C to Dual Gigabit Ethernet Adapter (US1GC301AU2R) lets you add two wired Gigabit Ethernet ports to a laptop or desktop using a single USB-C or Thunderbolt 3 port. The adapter also includes a USB 3.0 Type-A port so you can continue to connect Type-A peripherals while using the adapter for network access. It supports full Gigabit bandwidth over USB 3.0 (5 Gbps) and is compatible with Chrome OS and Windows 8.1 natively; Mac OS X 10.10 is supported with driver installation.

Advantages

This adapter delivers reliable Gigabit network performance without installing third‑party drivers on supported systems, using the 5 Gbps USB 3.0 link to avoid bottlenecks. It provides two GbE ports for connecting to separate networks or for redundancy, and includes features such as Wake-On-LAN, VLAN tagging, Auto-MDIX, checksum offload and large send offload for improved network efficiency. The integrated USB 3.0 Type-A port preserves connectivity for USB-A devices, and the reversible USB-C connector simplifies insertion and reduces port wear.

Suitable for

Laptops or desktops with a USB-C or Thunderbolt 3 port that need wired Ethernet
Users who require two separate Gigabit Ethernet connections or redundant links
Environments where USB-A peripherals must remain connected while adding wired network access

How to use

Plug the adapter into a free USB-C or Thunderbolt 3 port on your computer. Connect one or both Gigabit Ethernet cables to the RJ-45 ports on the adapter and connect the other ends to your network equipment. If you need to attach a USB-A peripheral, plug it into the integrated USB 3.0 Type-A port on the adapter. On Chrome OS and Windows 8.1, the adapter should be recognized automatically; on Mac OS X 10.10 install the provided driver before use.

Usage recommendations

For best performance, use Cat5e or better Ethernet cables and ensure your USB-C port supports USB 3.0/3.1 Gen 1 or Thunderbolt 3. Keep drivers updated on Mac systems and avoid using passive USB hubs between the adapter and the host to prevent bandwidth or power issues.
