UGREEN CM199 USB-C 3.1 Gen1 to Gigabit Ethernet Adapter — Gray

Description

From the Manufacturer

The UGREEN CM199 delivers up to 1Gbps wired Ethernet speed using the proven AX88179A chipset, making it an indispensable tool for any USB-C or Thunderbolt 3-equipped device without a built-in Ethernet port.

Wired Is Better — Every Time
Converting your USB-C port to a Gigabit Ethernet port gives you a faster, more reliable network speed than Wi-Fi — no interference from neighboring networks, no dead zones, no speed fluctuations from distance or walls. Whether you’re on a video call, transferring large files, or gaming online, a wired connection keeps latency low and speeds consistent. It’s also a perfect solution for devices with a failed or missing RJ45 port that need to connect to a wired network.

Backwards Compatible, Universally Useful
The adapter supports 10/100/1000 BASE-T Ethernet networks and provides data transfer at up to 5Gbps over USB 3.1 Gen1. Whether you’re plugging into a modern Gigabit office switch or an older 100Mbps router, the CM199 adjusts automatically to the fastest speed available on the network.

Compact, Cool & Status-Aware
Encased in a slim aluminum alloy shell for efficient heat dissipation and long-term durability, the CM199 is small enough to stay plugged in permanently or slip into any laptop bag. An integrated LED indicator shows connection status and live data activity — green for connected, flashing for active data transfer.

Plug & Play on Almost Everything
No drivers needed on Windows 10/11, macOS, Chrome OS, Linux, or iPadOS — just plug in and go. For Windows 7 or XP, a driver download is required.
