UGREEN CM845 AX900 Wi-Fi 6 Bluetooth 5.4 Dual Band USB Wireless Adapter

UGREEN CM845 AX900 Wi-Fi 6 Bluetooth USB Wireless Adapter

The UGREEN CM845 (model 75109) is a two-in-one USB adapter that adds both dual-band Wi-Fi 6 and Bluetooth 5.4 to a desktop PC or laptop. It is useful for computers that have no wireless card, or for older machines whose built-in Wi-Fi and Bluetooth are slow, unstable or no longer working. One small device in a single USB port handles your internet connection and your wireless accessories together.

On the Wi-Fi side, the adapter supports 802.11ax along with older a/b/g/n/ac standards. UGREEN rates it at up to 600 Mbps on the 5 GHz band and 286 Mbps on the 2.4 GHz band, giving the AX900 class. The 5 GHz band is good for streaming, video calls and downloads near the router, while 2.4 GHz reaches further through walls in a home or office.

Bluetooth 5.4 lets you pair headphones, speakers, keyboards, mice and game controllers with the same adapter. It uses a Realtek chipset, a USB 2.0 connection and an external 6 dBi high-gain antenna to improve signal reception. UGREEN lists support for Windows 10 and Windows 11, as well as Linux kernel 3.15 to 6.11, so it suits most modern home and office desktops, gaming PCs and laptops that need an upgrade.

Dual-Band Wi-Fi 6 Up to 600 Mbps

With Wi-Fi 6 support, the CM845 can make better use of a modern router than an old Wi-Fi 4 or Wi-Fi 5 card. You can choose the 5 GHz band for faster speed or the 2.4 GHz band for longer reach, depending on where your PC sits.

Bluetooth 5.4 for Wireless Accessories

The built-in Bluetooth 5.4 radio removes the need for a separate Bluetooth dongle. Wireless earbuds, a speaker, a keyboard and a mouse can all connect to the computer through the same USB port that provides Wi-Fi.

External 6 dBi High-Gain Antenna

Unlike tiny nano adapters, the CM845 has an external 6 dBi antenna. This helps a desktop placed under a desk or in a room away from the router hold a steadier signal.

Simple Plug-In Upgrade for Older PCs

Adding wireless to a desktop usually means opening the case to fit a PCIe card. With the CM845, you simply plug it into a free USB port. This makes it a practical choice for office desktops, home PCs and laptops with a damaged internal card, and it can be moved to another computer whenever needed.

SoftAP Mode to Share a Connection

Besides normal station mode, the adapter supports SoftAP mode. A PC connected by Ethernet can use it to create a small Wi-Fi hotspot for a phone or another device nearby.

Windows and Linux Compatibility

UGREEN lists support for Windows 10, Windows 11 and Linux kernel 3.15 to 6.11. Security options include WPA-PSK and WPA2-PSK, plus 64-bit and 128-bit WEP for older networks. macOS is not listed in UGREEN's official specifications.
