Dual-band wireless rate of 1300Mbps (2.4GHz 400Mbps+ 5.8Hz867Mbps), online video and games are and smoother. High-speed USB3.0 interface, bidirectional transmission and low loss. The antenna adopts a flexible rotation design, supports 180 free rotation, can be adjusted according to habits and signal strength, improves signal sensitivity, and enjoys high-speed Internet speed at any time. -MIMO technology allows multiple antennas of the router to multiple devices at the same time, so that each device is treated with high priority, making the Internet access smoother. The side cooling hole design effectively reduces the working temperature of card and continues to a high-efficiency network.
