Alfa AWUS036AXER Wi‑Fi 6 USB Adapter 1800 Mbps Dual-Band USB 3.2 Gen 1

AWUS036AXER is a WiFi 6 (802.11ax) 2x2 dual-band USB adapter that adds wireless connectivity to compatible laptops and desktop PCs. It operates on both 2.4 GHz and 5 GHz bands and supports IEEE 802.11a/b/g/n/ac/ax, allowing the same adapter to work with current WiFi 6 networks and supported earlier wireless standards. The adapter is based on the Realtek RTL8832BU chipset and uses a 2T2R WLAN design. Its listed wireless capability reaches a combined class of 1800 Mbps, with 802.11ax data rates up to 573.5 Mbps on 2.4 GHz and up to 1201 Mbps on 5 GHz. These figures describe the supported link rates for each WiFi 6 band rather than a guaranteed application throughput.

Support for OFDMA and MU-MIMO extends the adapter’s WiFi 6 feature set, while backward compatibility covers 802.11ac, 802.11n, and legacy 802.11a/b/g operation. Supported rates include up to 866.7 Mbps with 802.11ac and up to 300 Mbps with 802.11n, alongside the lower rates defined for 802.11a/g and 802.11b modes. This range makes the adapter suitable for systems that may encounter networks using different generations of IEEE 802.11 technology. Wireless security options include WEP 64/128-bit together with WPA, WPA2, and WPA3, providing compatibility with networks configured for the listed encryption methods. AWUS036AXER therefore combines dual-band access, WiFi 6 operation, and broad standards support in a single USB wireless interface.

The adapter connects through a USB 3.2 Gen 1 Type-A interface, providing a direct link between the host computer and the wireless hardware. Its antenna system is integrated into the compact enclosure and uses a 2x2 configuration, so no external antenna installation is required. A WiFi status LED gives a simple visual indication of wireless activity during operation. The body measures 65 x 24 x 10 mm and weighs 10.5 g, making the device compact for use with laptops or desktop PCs while keeping the complete antenna system inside the adapter itself. These physical characteristics are especially relevant where users want a small external wireless adapter without separate antenna elements or additional mounting components.

AWUS036AXER operates from a 5 V DC input rated at 800 mA, with maximum power consumption specified as 0.8 A at 5 V. The operating temperature range is 0 °C to 40 °C, defining the environmental limits to consider when choosing where the adapter will be used. Operating-system support covers Windows 10 and Windows 11, so host compatibility should be checked against these listed platforms before deployment. Together with the integrated antenna design and Type-A USB connection, these characteristics simplify physical setup on supported systems because no external antennas have to be attached. The USB interface, status indication, power requirements, and antenna system are therefore contained within one compact device.
