USB Wifi dongle/adapter

Specifications

Wi-Fi Standard

Look for IEEE 802.11n (basic), 802.11ac (Wi-Fi 5 for dual-band), or Wi-Fi 6/6E/7 for maximum multi-gigabit throughput and low latency.Wireless Speed (Bandwidth): Measured in Mbps or Gbps. Entry models offer 150–300 Mbps; dual-band AC600/AC1300 models offer 433 to 1300 Mbps; advanced Wi-Fi 6/7 adapters exceed 2,000 Mbps.Frequency Bands: Single-band (2.4 GHz only) works for basic web browsing; dual-band (2.4 GHz and 5 GHz) or tri-band (adding 6 GHz) reduces interference and handles heavy traffic.USB Interface Version: USB 2.0 caps maximum throughput around 480 Mbps (ideal for 150Mbps–300Mbps adapters), while USB 3.0 or higher is required for fast AC1200+ and Wi-Fi 6 speeds.Antenna Design: Nano/mini adapters use internal antennas for portability, whereas external or high-gain adjustable antennas provide better signal reach and wall penetration.Security Protocols: Ensure support for WPA2 or modern WPA3 encryption to protect your network connection.OS Compatibility: Verify driver support for your specific operating system (Windows 10/11, macOS, or Linux flavors).
