The ANDOWL Q-A220 Wireless Receiver 1200Mbps is a dual-band USB Wi-Fi adapter designed to give desktops and laptops fast wireless internet connectivity over both 2.4GHz and 5GHz networks. It supports the IEEE 802.11ac wireless standard, offering combined theoretical speeds of up to 1200Mbps typically around 867Mbps on the 5GHz band and 300Mbps on 2.4GHz.

Key features include:

• Dual-band Wi-Fi support (2.4GHz & 5GHz)
• High gain 6dBi external antenna for improved signal strength and range
• USB 2.0 connectivity
• Compatible with Windows, Linux, and Mac OS systems
• Supports wireless security protocols including WPA/WPA2 encryption
• Suitable for streaming, gaming, video calls, and faster browsing on compatible routers

The 5GHz band is especially useful for higher-speed connections with less interference, making it better for HD streaming and online gaming, although its range is usually shorter than 2.4GHz. Real-world speeds will depend on router quality, distance, interference, and USB port performance.
