Questions about this item

What real-world speed can I expect from the 286.8 Mbps rating on this Wi-Fi 6 adapter?

The 286.8 Mbps figure is the maximum physical-layer rate under 802.11ax at 2.4 GHz. Actual throughput will be lower due to overhead, signal quality and channel congestion.

Which USB standard does the dongle use and does it limit the 286.8 Mbps link?

The adapter plugs into a USB port and uses the AIC8800 chipset. The USB connection does not bottleneck the 286.8 Mbps 802.11ax rate at 2.4 GHz.

Will the 20 × 15 × 6 mm body block adjacent ports on my laptop?

The dongle measures 20 mm high, 15 mm wide and 6 mm deep. Its compact footprint leaves most neighbouring USB ports free on typical laptops.
