From the Manufacturer

The UGREEN CM209 is a powerful and reliable solution for adding Gigabit Ethernet connectivity to any device with a USB-A port. Whether you’re connecting a laptop, desktop, gaming console, or older machine that lacks a built-in Ethernet port, the CM209 delivers high-speed wired internet without compromise.

Wired Is Better — Every Time
Full 10/100/1000Mbps Gigabit Ethernet performance makes the CM209 faster and more reliable than most wireless connections. No Wi-Fi interference, no dead zones, no speed drops. Whether you’re on a video call, streaming 4K content, gaming online, or transferring large files across a network — wired is always the more stable choice. USB powered with no external power supply required, it draws everything it needs from your USB port.

AX88179A — The Chipset That Delivers
The high-performance AX88179A chipset is the same proven silicon used across UGREEN’s professional-grade Ethernet adapters, delivering consistent gigabit speeds and long-term reliability. The adapter also supports USB 3.0 data transfer at up to 5Gbps and is fully backwards compatible with USB 2.0 and USB 1.1 ports.

Nintendo Switch Ready
Fully compatible with Nintendo Switch and Switch OLED — connect it to the dock’s Ethernet port for ultra-smooth, lag-free online gaming with a wired connection that Wi-Fi simply can’t match for consistency.

Premium Aluminum, Compact Size
The aluminum unibody case is anti-fingerprint and anti-corrosion, providing excellent heat dissipation and long-term durability in a compact form factor that fits any laptop bag or pocket. Link and Activity LEDs keep you informed of connection status and live data transfer at a glance.
