The UGREEN CM845 (75109) combines AX900 dual-band Wi-Fi 6 and Bluetooth 5.4 in a single USB adapter. Designed for compatible computers, it supports theoretical wireless link rates of up to 600Mbps on 5GHz and 286Mbps on 2.4GHz, along with Bluetooth connectivity for supported wireless accessories.
Its 6dBi external high-gain antenna, Realtek chipset and USB-A interface make it a practical solution for upgrading desktop and laptop connectivity without installing an internal wireless card.
The UGREEN CM845 (75109) is a USB 2.0 wireless adapter combining Wi-Fi 6 and Bluetooth 5.4 functionality. It supports 2.4GHz and 5GHz wireless networks, features a 6dBi external antenna and uses a Realtek chipset. Designed for compatible computers, it offers a convenient external solution for connecting to wireless routers and pairing Bluetooth devices such as keyboards, mice, headphones and speakers.
The CM845 supports IEEE 802.11ax Wi-Fi 6 alongside earlier compatible wireless standards. It offers theoretical link rates of up to 600Mbps on 5GHz and 286Mbps on 2.4GHz, making it suitable for general internet access, video streaming, online meetings and everyday networking.
The AX900 designation represents a combined theoretical wireless speed class, not a guaranteed internet download speed. Actual performance depends on router capabilities, signal conditions, interference and the internet connection.
The adapter supports both 2.4GHz and 5GHz frequency bands, allowing users to connect to compatible dual-band wireless routers. The 2.4GHz band provides broad compatibility, while the 5GHz band offers additional wireless capacity in suitable environments.
Users can select an available network according to coverage and performance requirements. The CM845 does not provide 6GHz Wi-Fi connectivity, which is associated with compatible Wi-Fi 6E and Wi-Fi 7 devices.
Unlike a Wi-Fi-only USB adapter, the CM845 also supports Bluetooth 5.4. This enables compatible computers to pair with supported Bluetooth headphones, speakers, keyboards, mice and other wireless peripherals.
Bluetooth features and connection quality depend on the paired accessory, operating system and installed drivers. Wi-Fi and Bluetooth are separate wireless functions provided through the same USB device.
The UGREEN CM845 features an external 6dBi high-gain antenna designed to support wireless reception. Its adjustable design helps users position the antenna according to the desktop layout and surrounding wireless environment.
Signal strength and connection stability depend on router distance, obstacles, interference and antenna placement. Positioning the antenna away from large metal objects can help maintain a suitable wireless connection.
The adapter connects through a USB Type-A 2.0 interface, providing Wi-Fi and Bluetooth connectivity without requiring a PCIe expansion slot. Its external design is useful for computers without built-in wireless functionality.
The CM845 uses a Realtek chipset for wireless operation. A compatible USB port and appropriate drivers are required. Actual data throughput is also subject to the limitations of the USB interface and wireless network conditions.
The CM845 supports Station Mode for connecting a computer to an existing Wi-Fi network and SoftAP Mode for creating a software-based wireless access point in supported configurations. SoftAP functionality depends on the operating system, driver and network-sharing settings.
Product documentation lists Windows 10, Windows 11 and supported Linux kernel versions 3.15 through 6.11. Driver installation may be required for Wi-Fi and Bluetooth functionality. Users should verify driver compatibility with their exact operating system before purchase.
