What's the real-world throughput ceiling of a USB 2.0 port?
Approximately 200-240 Mbps for sustained data transfer, despite a 480 Mbps theoretical maximum, well below what modern WiFi 6/6E/7 adapters can achieve.

Does USB port type matter for the UGREEN AX900 adapter?
No β the AX900's own WiFi hardware maxes out around 218-224 Mbps, which is already below the USB 2.0 ceiling, so plugging it into USB 3.0 only gives aβ¦

How much does USB 3.0 improve the WAVLINK BE6500's speed compared to USB 2.0?
A 3.1x difference β 237 Mbps on USB 2.0 versus 741 Mbps on USB 3.0, the largest port-dependent gap of all five adapters tested.
