Dual-band USB Wi-Fi adapter

This USB wireless adapter adds 802.11ac dual-band connectivity to a PC, laptop or Mac. It operates on 2.4 GHz at 300 Mbps and 5.8 GHz at 867 Mbps for a combined link rate of 1200 Mbps. A 5 dBi high-gain antenna is included for extended range. The adapter connects via USB 3.0 and is backward compatible with 802.11a/b/g/n networks.

Upgrade from single-band USB 2.0 adapters

Replacing a single-band 2.4 GHz USB 2.0 dongle removes the 300 Mbps ceiling and adds the cleaner 5.8 GHz band. The jump is worth it when the router supports 802.11ac and the USB port is 3.0, because USB 2.0 caps throughput well below the adapter’s 867 Mbps 5 GHz rate. Older operating systems from Vista to 10 and Mac OS X are supported without extra drivers.

Capacity and headroom

The adapter comfortably handles HD video streaming, video calls and general browsing on either band. On 5.8 GHz it sustains higher throughput in congested environments, while 2.4 GHz reaches farther through walls. It runs out when the USB host is limited to 2.0 speeds or when the router lacks 802.11ac, because the 1200 Mbps link rate cannot be realised. The single antenna limits spatial streams to one.

Questions about this item

Does the 5 dBi antenna need extra clearance behind a desktop PC?

The antenna folds and rotates, so it clears most rear-panel layouts without blocking adjacent USB ports.

What driver step is required on Windows 10 before the adapter reaches 867 Mbps on the 5.8 GHz band?

Windows 10 installs a basic driver automatically; run the supplied setup or download the Realtek 8812AU driver to enable full AC1200 rates.

How often should the USB 3.0 connector and antenna hinge be inspected for wear?

Check the connector and hinge every six months; reseat the plug and tighten the antenna if signal drops or the joint feels loose.
