Dual-band USB 3.0 Wi-Fi adapter

This YINGHUA adapter adds 802.11ac wireless to any desktop or laptop with a spare USB 3.0 port. It operates on both 2.4 GHz and 5.8 GHz bands, delivering up to 1300 Mbps total link rate. The tiny 37.5 mm body stays flush with the chassis, making it practical for travel or permanent installation. It suits users who need a quick wireless upgrade without opening the case.

Driver install and common issues

Windows 7 through 10 (32-bit and 64-bit) and Mac OS are supported, but drivers must be downloaded from the supplier links; no CD is included. The RTL8812BU chipset is recognised automatically on recent Windows builds, while older releases may need the manual package. A frequent snag is plugging the dongle into a USB 2.0 port, which caps throughput well below the rated 867 Mbps on 5.8 GHz.

Real-world throughput and limits

The 2.4 GHz radio tops out at 400 Mbps (11n) and the 5.8 GHz radio at 867 Mbps (11ac), so combined traffic never exceeds 1300 Mbps. The built-in 2 dBi antenna and 18 dBm transmit power handle typical home or office ranges, but walls and distance will reduce usable speed. Access-point mode lets the host share its wired connection, yet the single radio cannot serve many clients simultaneously.

Questions about this item

How do I verify the adapter is delivering the 867 Mbps link speed on the 5.8 GHz band after installation?

Open the network adapter status in Windows or the Wi-Fi utility on Mac; the connection details should show a 5.8 GHz link rate at or near 867 Mbps when associated with an 11AC access point.

What comes in the box and is a separate driver disc or cable required?

The package contains the mini USB 3.0 adapter with its built-in 2 dBi antenna; drivers are downloaded from the supplied links for Windows or Mac, and no extra cable or disc is needed.

Should I choose the 2.4 GHz or 5.8 GHz band for the 1300 Mbps rating?

The 1300 Mbps figure combines both bands — 400 Mbps on 2.4 GHz (11N) and 867 Mbps on 5.8 GHz (11AC) — so select 5.8 GHz for the higher single-band throughput.
