UGREEN AX1800 Dual-Band Wireless USB Adapter Wi-Fi 6 – UG-90340

The UGREEN AX1800 Dual-Band Wireless USB Adapter Wi-Fi 6 (UG-90340) is a high-speed USB Wi-Fi adapter designed to add modern wireless connectivity to compatible desktop computers and laptops. Using Wi-Fi 6 technology, it supports dual-band 2.4 GHz and 5 GHz connections with theoretical speeds of up to 574 Mbps on 2.4 GHz and 1201 Mbps on 5 GHz, for an AX1800 class combined rate. The adapter uses a USB 3.0 interface and features dual antennas, OFDMA, MU-MIMO, 1024-QAM, and Beamforming technologies to improve wireless efficiency, capacity, and signal performance on compatible networks. It also supports WPA3, WPA2, and WPA security protocols for secure wireless connections. The UGREEN UG-90340 is based on the CM499 model and is designed primarily for Windows 10 and Windows 11 systems. A compatible Wi-Fi 6 router is recommended to take full advantage of its Wi-Fi 6 features and maximum theoretical speeds.

Product Features

Wi-Fi 6 AX1800 Wireless Connectivity

The UGREEN UG-90340 uses Wi-Fi 6, also known as IEEE 802.11ax, to provide faster and more efficient wireless networking than older Wi-Fi standards. It supports a combined theoretical AX1800 class speed of up to 1800 Mbps across the 2.4 GHz and 5 GHz bands.

Dual-Band 2.4 GHz and 5 GHz Wi-Fi

The adapter operates on both 2.4 GHz and 5 GHz frequency bands. The 2.4 GHz band provides up to 574 Mbps and can offer broader coverage, while the 5 GHz band supports up to 1201 Mbps for higher-speed wireless applications when conditions and network equipment allow.

5 GHz High-Speed Performance

The 5 GHz band provides theoretical wireless speeds of up to 1201 Mbps, making the adapter suitable for high-bandwidth activities such as HD and 4K streaming, online gaming, video conferencing, large downloads, and local network file transfers.

Wi-Fi 6 OFDMA Technology

OFDMA allows compatible Wi-Fi 6 networks to manage multiple devices more efficiently by dividing wireless channels into smaller resource units. This can improve network efficiency and responsiveness in environments with multiple connected devices.

MU-MIMO Support

MU-MIMO technology allows compatible wireless equipment to communicate with multiple devices more efficiently. When used with a compatible Wi-Fi 6 router, it can help improve overall network capacity and wireless performance.

1024-QAM Support

The adapter supports 1024-QAM modulation, a Wi-Fi 6 technology that enables higher data rates under suitable signal and network conditions.

Beamforming Technology

Beamforming helps direct wireless transmission toward compatible connected devices, which can improve signal efficiency and stability compared with transmitting energy uniformly in all directions.

USB 3.0 Interface

The UGREEN UG-90340 uses USB 3.0 for connection to a compatible computer. The high-speed USB interface helps provide sufficient bandwidth for the adapter’s high-speed wireless connection.

Dual Antennas

The adapter incorporates two antennas to support its dual-band wireless communication and help improve signal reception and transmission.

WPA3 Wireless Security

The UG-90340 supports modern WPA3 security alongside WPA2 and WPA options, providing stronger wireless security when connected to a compatible router configured with the corresponding security protocol.

Backward Compatibility

The adapter supports Wi-Fi 6 and earlier IEEE 802.11 standards, allowing it to connect to compatible networks that use older wireless technologies. Full Wi-Fi 6 benefits require a compatible Wi-Fi 6 router or access point.

Easy Wireless Upgrade

The USB design provides a convenient way to add or upgrade Wi-Fi connectivity on a compatible desktop PC or laptop without installing an internal wireless network card.

Suitable for Streaming, Gaming, and Work

The high-speed dual-band connection is suitable for online gaming, video streaming, video conferencing, web browsing, downloads, cloud applications, and other everyday networking tasks. Actual performance depends on the router, signal strength, network congestion, interference, distance, and other environmental conditions.
