UGREEN CM845 (75109) AX900 Wi-Fi 6 & Bluetooth 5.4 Dual-Band USB Adapter

The UGREEN CM845 is a 2-in-1 USB dongle that adds both Wi-Fi 6 and Bluetooth to a desktop or laptop from a single port. One adapter covers the wireless internet connection and the pairing of keyboards, headphones, printers and game controllers, which saves both a USB port and the cost of a second dongle. The wireless side is 802.11ax with an AX900 rating, reaching up to 600 Mbps on 5GHz and up to 287 Mbps on 2.4GHz, and it runs in Station mode or SoftAP mode so the machine can also share its connection as a hotspot. Encryption covers WPA-PSK, WPA2-PSK and WEP. Bluetooth 5.4 handles accessories and stays backward compatible with 5.3, 5.2, 5.0 and 4.0 devices. A 6dBi external high-gain antenna is fitted in place of a flush stub, which helps the signal through walls and across a flat. It connects over USB 2.0 with the driver built in, and is supported on Windows 10 and 11 and on Linux kernel 3.15 through 6.11. The antenna makes it the sensible choice when the router is a room or two away, whether that is a desktop in a back bedroom or an office machine behind a concrete wall, and it saves running a long cable across the floor. Angle the antenna towards the router for the steadiest link.
