Dual-band USB 3.0 adapter

The KINGARD USB Wi-Fi adapter adds 802.11ac wireless connectivity to desktops and laptops through a USB 3.0 port. It targets users who need a quick upgrade to dual-band AC1300 speeds without opening the case. Driver installation is required on most platforms, though Windows 10 offers plug-and-play operation. Smart TVs running Android are not supported.

5 dBi antenna and realistic throughput

The dual-band 5 dBi antenna delivers up to 867 Mbps on the 5 GHz band and 400 Mbps on the 2.4 GHz band. Actual throughput depends on router capability, distance and interference; the USB 3.0 interface provides headroom well above the wireless link rate. Performance will drop when the signal must penetrate thick walls or when many clients share the same channel. Buyers needing consistent multi-gigabit speeds should consider a wired connection.

CD driver and OS coverage

A driver CD is bundled for Windows 11, 10, 8.1, 8, 7, Vista and XP, plus macOS 10.6 through 10.15.3 and Linux kernels that support the RTL8812BU chipset. The disc simplifies first-time setup on systems without internet access. No additional software utilities or management tools are mentioned in the specifications.

Questions about this item

Will this USB 3.0 adapter work on my desktop that only has USB 2.0 ports?

Yes, the adapter is compatible with USB 2.0 ports, though maximum throughput will be limited to the slower USB 2.0 bus speed.

How can I verify the RTL8812BU chip is delivering the stated 867 Mbps on the 5 GHz band?

Connect to a 5 GHz network, open the adapter status in your OS, and confirm the link speed shows 867 Mbps; then run a local throughput test to measure real-world performance.

Does the package include a driver CD, or do I need to download drivers for Windows 7 separately?

A driver CD is included in the box; it contains the necessary drivers for Windows 7 and other supported systems that are not plug-and-play.
