UGREEN CM496 (90339) AC650 Dual Band Wireless USB Adapter fixes weak Wi-Fi?
Slow wireless speeds ruin work, gaming, and streaming. The UGREEN CM496 (90339) AC650 Dual Band Wireless USB Adapter targets dropped signals, poor range, and unstable connections on desktops and laptops that lack modern Wi-Fi support.
Built by Ugreen, this adapter fits users who need reliable dual-band wireless without replacing hardware. It belongs to the Network and Router category under the WiFi Adapter sub-category, sold officially at PCB Store in Bangladesh.
UGREEN CM496 (90339) AC650 Dual Band USB Adapter overview
The UGREEN CM496 is a compact external WiFi adapter with a high-gain antenna. It connects through USB and supports Wi-Fi 5 for balanced speed and stability.
This model targets daily computing. It suits home offices, study setups, and media PCs. Users gain access to both 2.4GHz and 5GHz bands without opening the system.
Core highlights include:
- Dual-band wireless support
- AC650 combined throughput
- External 6dBi high-gain antenna
- USB 2.0 interface for wide compatibility
- Support for AP mode
Performance and wireless speed of UGREEN CM496 (90339)
The adapter supports a total data rate of up to 650 Mbps. The speed splits across two frequency bands.
- 5GHz band: Up to 433 Mbps
- 2.4GHz band: Up to 200 Mbps
This structure suits mixed usage. The 5GHz band handles video streaming and downloads. The 2.4GHz band supports longer range and legacy routers.
The adapter follows IEEE 802.11 a/b/g/n/ac standards. This range allows smooth pairing with older and newer routers.
Transmit power stays within ≤20dBm. That level balances coverage and regulatory safety.
High-gain antenna advantage on UGREEN CM496 (90339)
Wireless stability depends heavily on antenna quality. Ugreen includes a 6dBi high-gain external antenna with this model.
The antenna improves reception in rooms with walls or interference. It helps maintain usable speeds at longer distances.
A unique design feature stands out:
- 90-degree and 180-degree rotatable antenna
This flexibility helps users adjust signal direction. Small changes often improve link quality on crowded networks.
USB 2.0 connectivity and system support
The UGREEN CM496 uses a USB 2.0 interface. That choice supports compatibility across many devices.
USB 2.0 still handles AC650 bandwidth comfortably for typical usage. It avoids driver conflicts common with older systems.
Supported operating systems include:
- Windows
- Linux
This makes the adapter useful for office PCs, student laptops, and Linux-based systems.
No Bluetooth support exists on this model. The focus remains strictly on Wi-Fi performance.
