Compact USB Wi-Fi Adapter for Dual-Band Networks

This Corn Electronics USB adapter adds 802.11ac dual-band wireless connectivity to desktops or laptops. It supports Windows from XP through 10 and Mac OS X 10.6 to 10.11. The device targets users needing a simple wireless upgrade without opening their computer case. It delivers up to 1.2Gbps combined throughput across both frequency bands.

Detachable 2dBi Antenna with Beamforming+ Technology

A detachable 2dBi omni-directional dual-band antenna screws onto the gray dongle for flexible positioning. The USB interface draws power directly from the host port, requiring no external adapter. Beamforming+ technology focuses the signal toward connected devices. Driver installation uses the included CD before the operating system's wireless utility manages connections.

Dual-Band Operation for Streaming and General Use

The adapter runs on 2.4 GHz at 300Mbps for everyday browsing and 5 GHz at 867Mbps for HD streaming or gaming. Separate bands reduce congestion by separating high-bandwidth tasks from background traffic. Soft AP mode creates a Wi-Fi hotspot from a wired Ethernet link when the driver software is active. Thermals and noise remain negligible during typical operation.
