Questions about this item

What operating system must my computer run for this adapter to work without extra drivers?

Windows 10 or 11 lets you plug it in and connect immediately; Windows 8.1, 8, 7, Vista, XP, Mac OS 10.9 to 10.15 and Linux kernel 2.6.24 to 4.7 are also supported with their own setup steps.

Will this USB 3.0 adapter slow down if I only have USB 2.0 ports on my older desktop?

It works in USB 2.0 ports but transfers at USB 2.0 speeds instead of the 10x faster USB 3.0 rate, so maximum wireless throughput drops below the 867 Mbps 5 GHz or 400 Mbps 2.4 GHz peaks.

How can I confirm the adapter is delivering the advertised 1200 Mbps class link after installation?

Open the network status panel in Windows or the Wi-Fi menu on Mac and verify the connection shows a 5 GHz link speed at or near 867 Mbps and a 2.4 GHz link at or near 400 Mbps.
