Alfa AWUS036AC AC1200 Dual-Band USB WiFi Adapter, 867 Mbps, 2x 5 dBi Antennas, USB 3.0

AWUS036AC is a dual-band AC1200 wireless USB adapter for connecting a compatible computer to 2.4 GHz and 5 GHz wireless networks. It supports IEEE 802.11a/b/g/n/ac, allowing one adapter to work across several generations of WiFi infrastructure. On 802.11ac networks, supported data rates reach up to 867 Mbps, while 802.11n operation reaches up to 300 Mbps. These figures describe the maximum rates supported by the respective wireless modes, helping users understand how the adapter fits both newer AC networks and older N-based environments. Dual-band operation also gives access to either supported frequency range without changing hardware, which is useful when the available network differs by location or configuration.

Wireless security support includes 64-bit and 128-bit WEP together with WPA-PSK and WPA2-PSK, enabling the adapter to connect to networks configured with any of these listed protection methods. Operating-system support covers Windows XP, Vista, 7 and 8.1, Mac OS 10.5.x through 10.9.x, and Linux. This range makes AWUS036AC suitable for the supported computers and software platforms without requiring a separate wireless adapter for each listed operating environment. By combining dual-band connectivity, backward compatibility across IEEE 802.11 standards, and AC1200-class wireless capability, the adapter provides a practical upgrade path for systems that need access to both 2.4 GHz and 5 GHz networks while retaining compatibility with supported earlier wireless standards.

The hardware design uses a USB 3.0 Type-A interface for connection to the computer, and the adapter is supplied with a USB desktop dock for flexible placement away from the host system. USB 3.0 supports a 5 Gbps connection to the PC, providing the wired host interface used by the adapter. Two detachable dual-band dipole antennas are connected through RP-SMA Female connectors. Each antenna is rated at 5 dBi, and the external arrangement is intended to support longer-range operation and improved signal stability. Because the antennas are detachable, they can be removed when needed, while the desktop dock gives the user another placement option instead of leaving the adapter directly attached to a computer port.

AWUS036AC measures 85 x 26 x 12 mm and weighs 25 g, so the main adapter occupies little space around the host system. Its compact body, detachable antennas, and included desktop dock give users several practical positioning options according to the available workspace and connection setup. The product uses an AC1200 wireless chip and is presented for applications requiring faster data rates, longer range, and signal stability. These characteristics are supported by the dual-band antenna system and high-speed USB 3.0 host connection. The resulting configuration combines the radio, antennas, and computer interface in a compact external adapter that can be connected directly to the PC or positioned on the desktop dock.
