The Gigabit Ethernet adapter is built with high-quality aluminum shells that are both beautiful and durable. The USB 3.0 ports feature high-grade aluminum shields, making the Ethernet hub more durable than other plastic products. This ensures a longer lifespan and a more reliable connection for your devices. This Ethernet adapter is a plug-and-play device that doesn't require any driver installation. It provides access to fast network speeds of up to 1000Mbps, making it possible for computers without an Ethernet port to connect to the network. Designed with a Green LED power light and network detection indicator, the USB C to Ethernet Adapter offers clear visibility of the network card's working status. The diagnostic indicator displays a steady yellow light for power and blinks green when data transfer is taking place. With the Ethernet port, you can enjoy faster and more stable wired network connection speeds up to 1 Gbps, and it's backwards compatible with 100Mbps/10Mbps RJ45 LAN. To reach 1Gbps, please ensure you connect with a CAT6 & up Ethernet cable. The USB C to Ethernet Adapter is a versatile 4 in 1 device that expands your connectivity options with 3 USB 3.0 ports and a 1000Mbps RJ45 gigabit port. All hub ports can work simultaneously, allowing you to connect multiple devices and peripherals with ease.
