GCROWN 1300Mbps USB 3.0 Wi-Fi Adapter

This dual-band USB adapter upgrades desktops and laptops to 802.11ac wireless performance. It targets users who need faster speeds than built-in wireless N hardware provides. The device suits home and office environments where reliable connectivity for streaming, gaming, or browsing is required. Buyers needing internal PCIe cards or Bluetooth capability should consider other form factors.

Dual-Band 5 GHz and 2.4 GHz Operation

The adapter delivers up to 867 Mbps on the 5 GHz band and 400 Mbps on the 2.4 GHz band for a combined 1300 Mbps link rate. Real-world throughput is limited by the host USB 3.0 port, router capabilities, signal obstacles, and network congestion. The two 5 dBi high-gain antennas improve reception and transmission stability compared to internal antennas. Performance drops significantly at long range or through dense walls.

Driver Installation and Common Issues

Windows 10 and 11 support plug-and-play operation without separate driver installation. Older Windows versions, macOS 10.9 to 10.15, and Linux kernel 2.6.24 to 4.7 require manual driver setup from the supplied media or manufacturer download. Common problems include selecting the wrong driver package for the OS version, USB 2.0 port bottlenecks halving throughput, and antenna positioning that does not clear nearby metal objects.

Questions about this item

Should I pick the 5 GHz or 2.4 GHz band for this adapter?

Use 5 GHz for up to 867 Mbps when close to the router; switch to 2.4 GHz for up to 400 Mbps through walls or at longer range.

What does the 1300 Mbps rating mean when I plug this into my PC?

It is the combined peak of both bands — 867 Mbps on 5 GHz plus 400 Mbps on 2.4 GHz — actual throughput will be lower due to overhead and signal conditions.

Does USB 3.0 limit the 1300 Mbps wireless speed in practice?

USB 3.0 runs at 5 Gbps, well above the adapter's 1300 Mbps wireless ceiling, so the port will not bottleneck the connection.
