UGREEN USB-C 31 Gen 1 to RJ45 Gigabit Ethernet Adapter Space Grey CM199 Review
The UGREEN USB-C 31 Gen 1 to RJ45 Gigabit Ethernet Adapter CM199 delivers lightning fast and ultra stable wired internet connectivity through a single USB Type C port. This UGREEN high performance adapter is engineered specifically for modern laptops, tablets, and smartphones that lack a built-in network port. Wrapped in a premium space grey aluminum enclosure, it serves as a critical accessory for professionals who demand uninterrupted network performance.
As modern computers become thinner, manufacturers permanently remove the physical network jack to save space. This architectural change forces remote workers, digital creators, and corporate employees to rely entirely on unpredictable wireless signals. The UGREEN CM199 resolves this vulnerability by establishing an instant, secure, and high speed hardware gateway directly to your local area network. It eliminates packet loss and wireless interference, ensuring your connection remains rock solid during mission critical tasks.
This dedicated Ethernet adapter is an indispensable asset for various modern computing environments. Software developers can download massive code repositories without fearing mid transfer dropouts. Online instructors and corporate executives can host high definition video webinars with zero latency or stuttering. It maximizes your local network bandwidth efficiency while maintaining an incredibly small, travel ready footprint.

Network Performance and Stability
Uncompromised Wired Speed
The RJ45 interface handles continuous data transmissions across 10, 100, and 1000 Mbps thresholds. It provides the low latency atmosphere needed for transferring massive backup files, processing cloud database tasks, and streaming live high bitrate video feeds. This hardwired connection removes the random disconnects, weak signals, and thick wall obstructions that limit standard wireless routers.
Intelligent Hardware Management
Equipped with an advanced internal logic controller, the adapter supports critical networking features like Wake on LAN, Full Duplex mode, and Half Duplex mode. It efficiently manages power consumption while reducing processor load on your host machine. The stable data packet processing ensures that your download and upload speeds remain symmetrical and consistent.
Premium Build Quality and Form Factor
The adapter features an industrial space grey anodized finish that complements high end laptops and modern tablets. This premium aluminum shell does not just look sleek, it actively draws heat away from internal logic boards to maintain optimal speeds under continuous load. The integrated heavy duty cable uses reinforced strain relief collars to prevent internal wiring fraying from daily twisting, pulling, and travel packing. Weighing next to nothing, it slides effortlessly into any small backpack pocket or carrying sleeve.
Compatibility and System Support
The CM199 functions seamlessly with host devices that feature an operational USB C or Thunderbolt 3 and Thunderbolt 4 port.
