What this adapter does

The YINGHUA AR9223 is a PCI Wi-Fi adapter that adds wireless networking to a desktop computer. It supports IEEE 802.11 b/g/n standards on 2.4 GHz and 5 GHz bands with a maximum link rate of 300 Mbps. Two external antennas provide 2x2 MIMO reception for improved signal stability. The card fits a standard PCI slot and works with Windows XP, 7, 8, and 10 in 32-bit and 64-bit editions.

Sustained throughput behaviour

The Atheros AR9223 chipset integrates baseband processing, ADC and DAC functions in a single CMOS device. It handles half-duplex OFDM, CCK and DSSS modulation with 20 MHz and 40 MHz channel operation up to 130 Mbps. Two simultaneous spatial streams use dual transmit and receive chains to maintain throughput under load. QoS filtering and error recovery help preserve consistent performance during extended transfers.

Installation notes and common issues

Insert the card into an available PCI slot and attach the two supplied antennas. Driver installation is required for the listed Windows versions; the adapter is not compatible with newer operating systems beyond Windows 10 64-bit. The PCI interface limits use to motherboards that still provide legacy PCI slots. Buyers needing PCI Express connectivity or modern OS support should consider a different adapter.

Questions about this item

Does the AR9223 chip run hot or draw much power during all-day use?

The AR9223 chip is designed for low power consumption and small size applications, so it stays cool and draws little power even during continuous operation.

What type of slot must my motherboard have for this PCI card to work?

Your motherboard needs a free standard PCI slot, not PCI Express, because the adapter uses a PCI interface.

Will this 2.4 GHz and 5 GHz card connect to my older 802.11 b/g router?

Yes, it supports IEEE 802.11 b/g/n standards, so it will fall back to 802.11 b/g speeds when paired with an older router.
