Ugreen CM845 (75109) AX900 Mbps Dual Band Wi-Fi & Bluetooth USB Adapter

The UGREEN CM845 (75109) is a versatile 2-in-1 USB wireless adapter that brings both Wi-Fi 6 (AX900) and Bluetooth 5.4 connectivity to devices like desktop PCs and laptops that lack modern wireless radios. Through its USB-A 2.0 interface, this compact black adapter delivers dual-band Wi-Fi support on both the 5 GHz band (up to ~600 Mbps) and the 2.4 GHz band (up to ~286 Mbps), perfect for smoother streaming, gaming, large downloads, and general web use with reduced interference thanks to the latest IEEE802.11ax standard. Equipped with a 6dBi high-gain external antenna, it improves signal strength and coverage compared with smaller dongles, helping connections reach farther across rooms and through obstacles. On the Bluetooth side, the Bluetooth 5.4 radio lets you pair wireless peripherals — such as headphones, keyboards, mice, speakers and controllers — with enhanced stability, lower latency, and backward compatibility with older Bluetooth versions. The adapter uses a Realtek chipset for stable performance, supports network encryption protocols like WPA-PSK/WPA2-PSK and both station (client) and SoftAP (hotspot) modes, and offers plug-and-play convenience on Windows 10/11 and many Linux kernels without complicated setup. With its rugged build and flexible connectivity, the UGREEN CM845 is great for upgrading older PCs or adding modern wireless capabilities without opening the case.
