Alfa AWUS036AX WiFi 6 USB Adapter with Dual 5 dBi Antennas, USB 3.2 Gen 1, Dual-Band 2.4/5 GHz

AWUS036AX is a WiFi 6 (802.11ax) 2x2 dual-band USB adapter designed to add 2.4 GHz or 5 GHz wireless connectivity to a compatible computer. Built around the Realtek RTL8832BU WLAN chipset, it supports the IEEE 802.11a/b/g/n/ac/ax standards, combining WiFi 6 operation with backward compatibility for earlier wireless generations. This broad standards support allows the adapter to connect to networks using supported legacy modes as well as 802.11ax, which is useful when the same computer may be used across different wireless environments. Dual-band capability also gives the user access to either supported frequency band according to the network being used, without requiring separate hardware for each supported standard.

Supported data rates reflect the range of wireless modes available through the adapter. Rates extend from the lower legacy values used by 802.11b and 802.11a/g through up to 300 Mbps with 802.11n and 866.7 Mbps with 802.11ac. For 802.11ax, the listed maximum rates are up to 573.5 Mbps and 1201 Mbps. These figures describe the supported connection rates for the respective standards rather than a single fixed operating speed, helping show how the adapter spans multiple generations of WiFi performance. Together, the 2x2 architecture, dual-band operation, and multi-standard compatibility make AWUS036AX suitable for systems that need access to both current WiFi 6 networks and supported older wireless infrastructure.

The adapter connects to the host system through a USB 3.2 Gen 1 Type-A interface, providing a direct wired connection between the computer and the wireless hardware. Its radio section uses two RP-SMA antenna connectors fitted with two detachable high-gain dual-band dipole antennas. Each supplied antenna is rated at 5 dBi and supports both 2.4 GHz and 5 GHz operation, so the same antenna set serves the adapter across either supported band. Because the antennas are detachable, they can be removed from the connectors when required for handling or storage. An integrated LED indicator provides a simple visual status reference during use.

AWUS036AX measures 87.4 x 28.5 x 12 mm, giving the adapter a compact body while retaining external antenna connections and a full-size Type-A USB plug. It operates from a 5 V supply and has a stated maximum power consumption of 3.6 W, defining the device’s electrical requirement during operation. The supported operating temperature range extends from -20 °C to 70 °C, which sets the environmental limits to consider when selecting where the adapter will be used. Operating-system support includes Windows 10, Windows 11, and Linux, allowing deployment with the listed desktop platforms without extending compatibility beyond those explicitly supported. These hardware, power, environmental, and software characteristics provide the practical information needed to plan connection, placement, and host-system compatibility.
