Product information

Description

The StarTech.com USB-C to Ethernet Adapter (C21GA-USB-ETHERNET) adds a Gigabit RJ45 network port to laptops, desktops and 2-in-1 systems via a USB Type-C connection and includes a USB-C to USB-A dongle for broader compatibility. It supports 10/100/1000 Mbps speeds and is compatible with Cat5 and higher cabling, providing a wired connection that is faster and more secure than wireless. The adapter uses a Realtek chipset, supports PXE and Wake-on-LAN (WoL), and is powered directly from the USB host with an integrated 6 in (15 cm) cable for extended reach and reduced strain.

Advantages

This USB-C to Ethernet adapter delivers Gigabit network performance up to 1000 Mbps while remaining compact and lightweight. Its included USB-A adapter increases device compatibility, and the Realtek chipset provides broad driver support on new and older systems for features such as PXE provisioning and Wake-on-LAN. The wired connection offers reduced latency and improved security compared with wireless networking, and built-in features like VLAN tagging, 9K Jumbo Frames and status LEDs meet common professional requirements.

Suitable for

Connecting laptops or desktops without an Ethernet port to wired networks
IT provisioning and maintenance using PXE and Wake-on-LAN
Streaming, large file transfers and network backups requiring stable Gigabit speeds
Travel or remote work where a reliable wired connection is needed

How to use

Connect the adapter's USB Type-C plug to your computer's USB-C port, or use the included USB-C to USB-A dongle if your system requires a Type-A connection. Plug an RJ45 Ethernet cable into the adapter and the network jack, then verify link/activity via the adapter's LEDs. Most modern operating systems will configure the adapter automatically; for legacy systems consult the StarTech.com driver resources if required. Use standard network settings on your computer or follow your organisation's network configuration procedures.

Usage recommendations

For optimal performance, use Cat5e or higher cabling and ensure your network equipment supports Gigabit speeds. Avoid sharp bends at the cable junction and allow the integrated 6 in cable to reduce strain on the connector. If PXE or Wake-on-LAN is required, confirm BIOS and network boot settings on the host system and test compatibility before deployment.
