  • Two-in-one Wi-Fi and Bluetooth adapter with dual antennas for stronger signal

What it is

The GCROWN 600 Mbps Dual-Band USB Wi-Fi Bluetooth Adapter adds wireless networking and Bluetooth to a desktop or laptop through a single USB port. It targets users who need a simple way to connect to 2.4 GHz or 5.8 GHz networks and pair Bluetooth peripherals on Windows 7 through 11. A mini CD is included for systems that cannot fetch drivers automatically. Vista, XP and Mac OS users must install drivers manually and lose Bluetooth support.

Capacity and headroom

The adapter delivers up to 433 Mbps on the 5.8 GHz band and 150 Mbps on the 2.4 GHz band for a combined 600 Mbps link rate. The 5.8 GHz band handles HD video streaming and online gaming with lower congestion, while the 2.4 GHz band covers general browsing and chat. Dual external antennas improve reception, but throughput will drop at longer range or through walls. Bluetooth works only on Windows 7, 8, 8.1, 10 and 11.

Deciding specification

Driver-free installation on Windows 7, 8, 8.1, 10 and 11 means the device is ready moments after plugging it in, provided the operating system can run the built-in installer. If the target machine runs Vista, XP or Mac OS 10.11 to 10.15, a driver install from the supplied mini CD is required and Bluetooth will not function. Buyers who need Bluetooth on those platforms should choose a different adapter.

Questions about this item

Will the GCROWN adapter work with my older desktop that still runs Windows 7?

Yes, the adapter supports Windows 7, 8, 8.1, 10 and XP for Wi-Fi and Bluetooth, so it will work with a Windows 7 desktop without extra drivers.

How do I know the RTL8821CU chip is delivering the 433 Mbps link on the 5.8 GHz band?

Connect to a 5.8 GHz network and check the link speed in your OS network status; it should show up to 433 Mbps when signal conditions allow.

Does the package include the mini CD for Vista or Mac OS 10.11 to 10.15, or do I need to buy it separately?

The mini CD driver is included in the box for Vista and Mac OS 10.11 through 10.15; no separate purchase is required.
