The UGREEN CM787 is a USB Wi-Fi adapter designed to bring modern wireless connectivity to computers running Windows 10 or 11. By utilizing the Wi-Fi 6E standard, it accesses the 6 GHz band alongside the traditional 2.4 GHz and 5 GHz frequencies, which helps reduce congestion in crowded network environments. This tri-band capability allows for speeds up to 2400 Mbps on both the 5 GHz and 6 GHz bands, while the 2.4 GHz band supports up to 574 Mbps. To ensure a stable and far-reaching signal, the device features two external high-gain adjustable antennas with 5dBi gain. These are connected via a USB 3.0 interface for fast data transfer between the adapter and your PC. For security, it supports the latest WPA3-SAE encryption, as well as WPA2 and WEP standards. The black dongle is versatile enough to operate as a receiver in Station Mode or as a wireless hotspot in SoftAP Mode, making it a practical choice for users who need to upgrade an older desktop or laptop to handle high-bandwidth tasks like streaming or gaming.
