Mini PCIe dual-band adapter

The YINGHUA SR71-E AR9280 is a new Mini PCIe wireless card that delivers 300Mbps across 2.4G and 5G bands. It fits laptops, all-in-one desktops, mini advertising players and industrial equipment with a Mini PCIe slot.

Works with Windows, Linux and macOS ≤10.13

Compatible with Win7, Win8, Win10, Vista, Linux and MacOS 10.13 or earlier; macOS above 10.13 is not supported. Lenovo and HP systems are explicitly excluded. Buyers who need support for newer macOS releases or those specific laptop brands should look elsewhere.

IEEE 802.11 a/b/g/n at 300Mbps

The card implements 802.11 a/b/g/n with a 400mW radio for a 300Mbps link rate. This single specification determines whether the adapter meets the throughput requirement for the intended deployment.

Questions about this item

What practical throughput does the 802.11n mini PCIe interface cap at?

The card is rated at 300 Mbps under the 802.11n standard across both 2.4 GHz and 5 GHz bands.

What slot and antenna connectors does the SR71-E need to fit?

It requires a mini PCIe slot and uses the standard U.FL antenna connectors found on most laptops and embedded boards.

How is the driver installed on Windows 10, and which step is often missed?

Windows 10 usually installs the Atheros AR9280 driver automatically; the step often missed is attaching both U.FL antennas before first boot so the card initialises correctly.
