What to know before buying

Listing details to confirm

The listing is inconsistent about transfer rates: it gives 1000 Megabits Per Second and 10/100/1000 Mbps, but also lists full-duplex figures up to 2000 Mbps. The Windows support statements differ, with one mentioning Windows 11 and Linux and another listing Windows 10/8.1/8/7/Vista/XP. The listed dimensions are unusually large for a PCIe card, so confirm physical measurements, operating-system support and the applicable rate with the selected listing before purchase. Customer feedback also varies on PCIe fit, connection stability and long-term reliability.
