The UGREEN CM199 is a compact USB-C to Gigabit Ethernet adapter designed to provide a stable, high-speed wired internet connection for devices that lack a built-in network port. By utilizing a USB 3.1 Type-C interface, it supports transfer speeds up to 1000 Mbps, though you will need a CAT6 or higher cable to reach this maximum performance. It also remains compatible with older 10 Mbps and 100 Mbps standards for broader versatility. Housed in a Space Gray aluminum alloy shell, the adapter is both durable and lightweight at only 30 g, making it easy to slip into a laptop bag for travel. This plug-and-play device works without drivers on modern systems like Windows 11/10, MacOS, iOS, Android, and the Nintendo Switch, while a driver disc is included specifically for users of Linux or older Windows versions like XP and 7. It is an ideal solution for owners of MacBook Pro, iPad Pro, or slim laptops such as the Dell XPS and Microsoft Surface who need reliable connectivity for gaming on a Steam Deck or handling large file transfers. Please note that it is not compatible with ARM-based Windows devices, including the Surface RT and Surface 2, nor the Wii U.
