UGREEN USB 3.0 to RJ45 Gigabit Ethernet Adapter - Grey (CM209)
Product details and customer reviews
The UGREEN CM209 USB 3.0 to RJ45 Ethernet Adapter converts a standard USB-A port into a wired Ethernet connection, making it useful for laptops, desktops, ultrabooks, and other compatible devices without a built-in RJ45 port.
With support for Gigabit Ethernet speeds up to 1000Mbps, it provides a more stable and consistent alternative to Wi-Fi for office work, large downloads, streaming, video conferencing, and other network-intensive tasks.
Gigabit Ethernet up to 1000Mbps
The adapter supports wired network speeds up to 10/100/1000Mbps on compatible equipment.
This makes it suitable for:
Office networks
Video conferencing
Large file downloads
Cloud applications
Streaming
Online gaming
Network troubleshooting
Actual speed depends on the router, Ethernet cable, internet connection, and host device.
USB 3.0 Connection
The adapter connects through a standard USB-A 3.0 port, providing enough bandwidth for Gigabit Ethernet operation.
It is also suitable for many computers that do not include a built-in Ethernet port.
RJ45 Ethernet Port
The built-in RJ45 port supports standard Ethernet cables and can be used with compatible routers, switches, modems, and network wall sockets.
For Gigabit speeds, a suitable Cat5e or higher Ethernet cable is recommended.
Stable Wired Connection
A wired Ethernet connection can provide better consistency than Wi-Fi in environments with interference, weak wireless coverage, or heavy network traffic.
This makes the CM209 useful for workstations, offices, hotels, classrooms, and home setups where a reliable connection is important.
Compact Grey Design
The adapter has a compact, lightweight body with a grey finish, making it easy to carry in a laptop bag or accessory pouch.
Its simple design is suitable for both office and travel use.
Plug-and-Play Convenience
On many modern operating systems, the adapter can work without manual driver installation.
Some older operating systems may require a driver depending on the exact system version.
