If you experience problems with detection, please contact us for driver installation instructions.
 
 
Note Regarding the 600 Mbps Speed:
This value represents the theoretical maximum speed under ideal laboratory conditions. The actual speed may vary due to various technical factors:
 
Hardware Limitations:
 
Maximum output power of the router (many home routers have lower throughput limits)
 
USB interface version of your computer (USB 2.0 theoretically limits speeds to ~480 Mbps, with practical throughput of approximately 280-380 Mbps)
 
Processor performance and bus bandwidth of the host device
 
Signal Interference:
 
Physical obstacles (walls/ceilings significantly attenuate 5GHz signals; 2.4GHz penetrates better but is more congested)
 
Channel conflicts from other Wi-Fi networks, Bluetooth devices, baby monitors, or microwaves (particularly in the 2.4GHz band)
 
Distance from the router (signal strength follows the 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 (speed test servers, website servers, etc.)
 
Recommendations for Optimal Performance:
 
Use USB 3.0 ports (marked in blue) for full bandwidth
 
Position with line-of-sight to the router
 
Conduct tests in the interference-free 5GHz band
 
Ensure the router supports 802.11ac/n standards
 
Keep router firmware and adapter drivers up to date
