USB 3.0 dual-band adapter

This USB 3.0 wireless adapter delivers dual-band connectivity at up to 1200Mbps, with 300Mbps on 2.4 GHz and 867Mbps on 5 GHz. It targets desktop and laptop users who need a portable way to add or upgrade Wi-Fi without opening the case. Adjustable dual antennas help stabilise the signal in typical home or office environments.

Upgrade from USB 2.0 or single-band dongles

The USB 3.0 interface supports up to 5 Gbps throughput, removing the bottleneck that limits older 2.0 adapters. The jump is worthwhile when your router offers 5 GHz AC speeds and you want consistent throughput for HD streaming or online gaming. It does not support TV boxes, printers or projectors.

Handles 5 GHz AC traffic; limited by AC1200 ceiling

The adapter comfortably handles 5 GHz connections up to 867Mbps and 2.4 GHz up to 300Mbps, which suits most current broadband tiers and local file transfers. It runs out when the network moves to Wi-Fi 6 (AX) speeds such as 2402Mbps on 5 GHz or when a PCIe card with external antennas is needed for maximum range. Driver installation is required on Windows 7 through 10; Mac 10.5 to 10.15 is supported.
