Product Overview of UGREEN CM845 AX900 USB WiFi Adapter

The UGREEN CM845 (Model 75109) sits in the Computer Accessories category under Converter and Splitters. It connects via USB 2.0 Type-A and focuses on wireless reception and sharing.

Wi-Fi 6 support brings higher efficiency per device. Dual-band operation balances range and speed. Bluetooth 5.4 handles multiple peripherals at once. The external antenna improves signal control without internal installation.

This adapter suits users seeking a fast wireless upgrade without opening a PC case.

Wireless Performance and Speed Breakdown

The UGREEN CM845 AX900 WiFi 6 & Bluetooth 5.4 Dual-Band USB Adapter supports IEEE 802.11ax. It stays backward compatible with older Wi-Fi standards.

Rated wireless speeds include:

• 5 GHz band: Up to 600 Mbps
• 2.4 GHz band: Up to 286 Mbps
• Combined throughput: Around 900 Mbps (AX900 class)

The 5 GHz band handles high-speed tasks with reduced interference. The 2.4 GHz band offers better wall penetration for distance coverage. Dual-band switching supports stable connections during movement or load changes.

Wi-Fi 6 Advantage in Daily Use

Wi-Fi 6 focuses on efficiency rather than raw speed alone. This matters in apartments, offices, and shared networks.

Key operational benefits include:

• Improved performance in crowded networks
• Lower latency during simultaneous connections
• Better bandwidth allocation across devices

The Realtek chipset manages these improvements at the hardware level. Users notice fewer drops and steadier throughput during video calls, downloads, and online gaming.

Bluetooth 5.4 with Multi-Device Support

Bluetooth capability defines the CM845 beyond Wi-Fi alone. Bluetooth 5.4 supports newer power and connection management features.

The adapter connects up to five different Bluetooth device types simultaneously. This supports keyboards, mice, headsets, speakers, and controllers at once.

Bluetooth stability matters for workstations and media setups. The CM845 handles these roles without needing separate dongles.

Antenna Design and Signal Control

A 6dBi external high-gain adjustable antenna improves reception quality. Adjustable positioning helps align signals with routers or access points.

This design benefits:

• Desktop PCs placed under desks
• Systems far from routers
• Rooms with signal obstacles

Unlike internal antennas, this external unit allows physical tuning. Small adjustments often result in noticeable signal gains.

Operating Modes and Network Flexibility

The UGREEN CM845 AX900 WiFi 6 & Bluetooth 5.4 Dual-Band USB Adapter supports two operating modes.

Receive Mode (Station Mode):

• Connects your PC to an existing Wi-Fi network

Launch Mode (SoftAP):

• Shares your wired or wireless internet as a hotspot

SoftAP helps laptops act as temporary access points. This suits travel, testing, or small shared workspaces.

Security Protocol Support

Wireless security stays essential for home and office environments. The adapter supports common encryption standards used by modern routers.

Supported protocols include:

• WPA-PSK
• WPA2-PSK
• WPA/WPA2 mixed modes
• 64-bit and 128-bit WEP

These options allow compatibility with older routers while maintaining secure connections where possible.

System Compatibility and Driver Experience

Compatibility remains one of this adapter’s strongest advantages.

Supported systems include:

• Windows 11 and Windows 10 (X86 and X64)
• Linux kernels from 3.15 to 6.11

Windows users benefit from built-in drivers. Plug-and-play operation reduces setup time. Linux users gain wide kernel support, helpful for distributions across different generations.

Physical Design and Desk Fit

The adapter stands roughly 11 cm tall including the antenna. This vertical form factor keeps airflow clear and reduces cable strain.

USB 2.0 interface matches broad system compatibility. Despite the interface limit, wireless performance remains consistent for AX900-class usage.

The compact footprint avoids desk clutter while maintaining antenna effectiveness.

Reliability, Warranty, and Brand Trust

UGREEN maintains a strong reputation in connectivity accessories. The CM845 reflects this focus on stable components and wide compatibility.

The product includes a 1-year warranty, offering reassurance for long-term use. Warranty coverage matters for wireless adapters exposed to daily plugging and repositioning.

This balance of durability and support builds confidence for both home and professional setups.

Who Should Choose the UGREEN CM845 AX900 Adapter

This adapter suits users who:

• Own desktops without built-in Wi-Fi
• Need stronger reception than internal cards
• Use multiple Bluetooth peripherals daily
• Run Windows or Linux systems
• Prefer external upgrades over internal installations

Gamers, remote workers, and media users benefit from stable wireless behavior without complex setup.
