## Long 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
