Startech USB 3.0 to Gigabit Ethernet Adapter
Add Gigabit Ethernet network connectivity to a laptop or desktop via a USB 3.0 port. With the USB31000S USB 3.0 to Gigabit Ethernet adapter, you can add a single RJ45 Ethernet port to a USB-enabled computer system, supporting connections to Gigabit networks at full bandwidth—something USB 2.0 adapters cannot achieve. This compact USB 3.0 network adapter is backward compatible with older USB 2.0/1.x computer systems (speed limited by the USB bus), making it an ideal portable replacement network adapter or laptop accessory. Additionally, the adapter supports features such as jumbo frames, VLAN tagging, and Wake-on-LAN (WOL), providing a versatile Gigabit networking solution for both home and business users.
