The advertised 600Mbps is the theoretical maximum speed under ideal laboratory conditions, while actual speeds may vary due to several technical factors:
 
‌Hardware Limitations:‌
The router's maximum output capability (many home routers have lower throughput ceilings)
Your computer's USB interface version (USB 2.0 limits speeds to ~480Mbps theoretically, with actual throughput around 280-380Mbps)
The host device's processor performance and bus bandwidth
 
‌Signal Interference:‌
Physical obstructions (walls/floors reduce 5GHz signals significantly; 2.4GHz is more penetrative but more crowded)
Co-channel interference from other WiFi networks, Bluetooth devices, baby monitors, or microwave ovens (especially in 2.4GHz band)
Distance from router (signal strength follows inverse-square law)
 
‌Network Environment Factors:‌
Bandwidth sharing with other connected devices
Protocol overhead (TCP/IP typically has 10-15% overhead)
Network congestion during peak hours
Server-side limitations (speedtest servers, website servers, etc.)
 
‌Suggestions for Optimal Performance:‌
Use USB 3.0 ports (blue-colored) for full bandwidth
Position closer to router with clear line-of-sight
Test with 5GHz band in interference-free environment
Ensure router supports 802.11ac/n standards
Update both router firmware and adapter drivers
