UGREEN CR111 (20256) USB 3.0 to Gigabit Ethernet Adapter

The UGREEN CR111 is a USB-to-Ethernet adapter that adds a wired network port to any machine with a spare USB-A port. It answers a common problem on modern hardware: thin laptops, TV boxes and consoles have dropped the RJ45 socket, yet still need a connection that does not wander with the Wi-Fi signal. The RJ45 side runs Gigabit Ethernet at 10/100/1000Mbps, while the host side is USB 3.0 with up to 5Gbps of headroom, so the network line rather than the adapter sets the limit. It is bus-powered and needs no supply of its own, and it stays backward compatible with USB 2.0 and 1.1 ports, where the network speed settles at around 100Mbps. Link and activity LEDs on the body show at a glance whether the cable is live and data is moving. Setup is plug-and-play on Windows, macOS, Linux and Chrome OS, and it works with the Nintendo Switch as well as computers. It earns its place during video calls and large downloads, at a desk close enough to the router to run a cable, and in offices where too many people are sharing the same wireless network. The dongle is small enough to leave in the laptop bag permanently. A one-year brand warranty is included.
