Questions about this item

What are the physical dimensions and weight of this BUANIIH 600Mbps USB adapter?

The adapter measures 1.25 in by 0.62 in by 0.31 in and weighs 0.018 kilograms, so it fits tightly spaced USB ports without blocking neighbours.

What is the driver installation process on Windows 7, and which step is often missed?

On Windows 7 the WiFi function installs automatically in under 30 seconds, but the Bluetooth feature requires a separate manual driver installation before it will work.

What ongoing software updates will this adapter need after setup?

Windows Update will supply any future driver revisions for the RTL8821CU chipset; no firmware tool or periodic re-pairing is required by the hardware itself.
