USB 3.0 Network Interface 3 USB 3.0 ports and 1 Gigabit RJ45 Ethernet port. This device extends USB connectivity by three ports and provides a wired network option for devices that do not have a RJ45 port. Speed Data Sync All three USB ports are true USB 3.0 with data transfer speeds up to 5 Gbps. This enables fast transfers of large files and is backward compatible with USB 2.0 and USB 1.1. Ultra Fast Networking The Gigabit Ethernet port supports up to 1000 Mbps, backward compatible with 100/10 Mbps. How fast is 1000 Mbps? Downloading a 1 Gbps HD movie can take less than 10 seconds. Widely Compatible Works with TypeA devices such as flash drives, keyboards, mice, hubs, Bluetooth transmitters/receivers, webcams, and other USB peripherals. The RJ45 port accepts all Ethernet cables, but Cat5e and above is recommended for faster networking. Use Scenarios Scenario 1: Improve a laptop or tablet that lacks an Ethernet port by adding a wired network connection while expanding USB peripheral options. Scenario 2: Create a compact desktop or laptop setup with extra USB ports and a stable wired network for work, streaming, or gaming. Scenario 3: Travel or shared workspaces where you need to connect multiple USB devices and access a wired network from a single USB hub.
