The StarTech C21GA-USB-ETHERNET USB-C/USB-A to Gigabit Ethernet adapter provides a wired network connection for PCs and laptops that lack a built-in RJ-45 port. The adapter connects to the host device via a USB-C or USB-A interface using the USB 3.2 Gen 1 standard. It supports data transfer rates of up to 1000 Mbit/s over standard copper cabling. As a dedicated wired networking device, it does not include Wi-Fi or Bluetooth. It uses 10/100/1000Base-T(X) technology to ensure stable link speeds.
This plug-and-play adapter draws power directly from the host USB port. It is compatible with Windows 7 to 11, macOS 10.11 to 14, and Linux. Two integrated LEDs provide visual feedback on network activity and link speed. Inside its grey plastic housing, a Realtek RTL8153B chipset handles data processing. At only 26 grams, the adapter is light enough to carry easily alongside a mobile workstation.
Key Features:- Wake-on-LAN support for remote device startup and network management
- 9000-byte jumbo frame capacity to handle large data payloads and reduce host overhead
- IEEE 802.1Q VLAN tagging support for segmented network traffic routing
- Full-duplex operation for simultaneous data transmission
- Auto-MDI/MDIX negotiation to eliminate the need for crossover Ethernet cables
