## Long 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
