Questions about this item

How do I confirm the adapter is running at 5 GHz 866 Mbps after installation?

Open the network adapter status on Windows or the Wi-Fi menu on Mac OS 10.9-10.15; the link speed should show 866 Mbps when connected to a 5 GHz AC router.

What comes in the box and do I need anything else to get started?

The package includes the USB Wi-Fi adapter, a user manual and a driver disc; no extra cables or antennas are required.

Should I choose the 2.4 GHz 300 Mbps band or the 5 GHz 866 Mbps band for 4K streaming?

Use the 5 GHz 866 Mbps band for 4K Ultra HD streaming; the 2.4 GHz 300 Mbps band is better for longer range through walls.
