USB 3.0 dual-band Wi-Fi adapter

The coolline RTL8812AU adapter adds 802.11ac wireless to any device with a standard USB 2.0 Type A port. It operates on 2.4 GHz and 5 GHz bands with a maximum link rate of 1200 Mbps using 2T2R MIMO. The integrated antenna keeps the dongle compact for desktop or laptop use.

Check USB port and OS support

Verify your system provides a USB 2.0 Type A socket; the adapter is backward compatible with USB 2.0 although the connector is USB 3.0. Supported operating systems include Windows 2000, XP, Vista, 7, CE, Linux and Mac. No internal slot or external power is required.

Thermals noise and power draw

The adapter draws power directly from the USB bus with no fan or moving parts, so it runs silently. Typical operation stays cool to the touch during sustained transfers. Security uses 64/128-bit WEP, WPA and WPA2 encryption without measurable performance penalty.

Questions about this item

Does the adapter include an external antenna or must one be purchased separately?

The adapter uses an integrated antenna, so no separate antenna is required.

Which chipset version should I choose for 1200 Mbps dual-band performance?

The Realtek RTL8812AU chipset delivers up to 1200 Mbps across 2.4 GHz and 5 GHz bands.

What real-world throughput can I expect from the 1200 Mbps rating on a USB 3.0 port?

The 1200 Mbps figure is the maximum PHY rate; actual throughput will be lower and depends on router capability, channel width, and interference.
