What the adapter does

The Graviton ZZL-RNU-ASD1503302 adds Wi-Fi and Bluetooth 4.2 to any PC with a free USB 1.1 or USB 2.0 port. It targets users who need basic wireless networking on Windows 7 through Windows 11 without installing an internal card.

Capacity and headroom

The radio supports IEEE 802.11n, g and b with a maximum link rate of 150 Mbps on the 2.4 GHz band across channels 1 to 14. Real-world throughput drops at the 10 metre indoor range limit and the adapter cannot use 5 GHz networks or newer Wi-Fi standards.

Thermals noise and power

The RTL8723DU chip draws between 100 mA and 200 mA depending on whether Wi-Fi and Bluetooth are active together. With a maximum RF output of 16 dBm and a 2 dBi antenna the adapter runs cool and silent because it has no fan or moving parts.

Questions about this item

Will the Graviton ZZL-RNU-ASD1503302 adapter work on a desktop that only has USB 1.1 ports?

Yes, the bus type is USB 1.1 / USB 2.0 so it will operate on older USB 1.1 ports, though throughput will be limited to the USB 1.1 bandwidth.

How can I confirm the RTL8723DU chip is delivering the stated 150 Mbps Wi-Fi link after installation?

Check the active connection properties in Windows 7, 8, 10 or 11; the link speed should show up to 150 Mbps when associated with an 802.11n access point on the 2.4 GHz band.

Does the box include any external antenna or driver disc, or must I supply them?

The adapter has a built-in 2 dBi antenna and supports Windows 7 through 11 natively, so no external antenna or separate driver media is required.
