Product information

Description

Instantly add a Gigabit Ethernet connection to a laptop, desktop or tablet with the StarTech.com USB-C to Gigabit Ethernet Adapter (US1GC30B). The compact black adapter uses a USB-C or Thunderbolt 3 port and the Realtek® RTL8153 chipset to deliver wired network access without installing an internal Ethernet card.

Advantages

The adapter supports full Gigabit bandwidth using USB 3.2 Gen 1 (5 Gbps) and provides 10/100/1000 Mbps network speeds with checksum offload (IPv4, IPv6, TCP, UDP) and large-send offload. It has native driver support for Chrome OS, macOS and Windows and is bus-powered from the host USB port, making it portable and easy to use. The product is covered by a 2-year warranty and North American lifetime technical support.

Suitable for

Connecting a laptop without an Ethernet port to wired networks
Desktops or tablets that need a compact external Ethernet interface
Environments requiring reliable Gigabit wired connectivity for large file transfers
Temporary or mobile workstations where portability and plug-and-play are needed

How to use

Connect the adapter to an available USB-C or Thunderbolt 3 port on your device and plug an Ethernet cable into the adapter's RJ45 port. The Realtek RTL8153 chipset provides native driver support for Chrome OS, macOS and Windows; on supported systems the adapter should be recognized automatically. Configure network settings in your operating system if a static IP or specific network parameters are required.

Usage recommendations

Use a Cat5e or higher-rated Ethernet cable to achieve full Gigabit performance. Ensure your host port supports USB 3.2 Gen 1 (5 Gbps) or Thunderbolt 3 for optimal throughput; older USB 2.0 ports will limit network speed. Keep firmware and OS drivers up to date for best compatibility.
