1. WiFi6 intelligent algorithm, more stable signal transmission. Compared with previous Wi-Fi5 wireless network cards, WiFi 6 intelligent algorithm can better assist the stable transmission of wireless signals, making the wireless transmission range wider and the 5G signal connected smoothly. 2. Dual-band high-speed AX900M, using WiFi6 dual-band technology, wireless speed up to 600Mbps (5G) + 286Mbps (2.4GHz), pure 5G signal brings a more enjoyable audio and video experience, 2.4GHz signal compatibility is stronger, adaptable to more devices, dual-band matching, signal transmission is more in place. 3. Bluetooth multiple devices can be connected at the same time, Bluetooth5.4 Bluetooth version, lower power consumption, smaller delay, can support 7 devices to connect at the same time, easily cope with various occasions, upgraded automatic reconnection function, no need for secondary pairing 4. Built-in iron antenna, more stable signal transmission, high-gain antenna, compared with traditional WiFi5 network card, signal reception is more stable and transmission range is longer, driver-free system compatible, support For Windowso10/11 (32/64 bit) 5. Multiple data encryption modes for surfing are safe and secure, support WPA3-SAE/WPA3/WPA2/WPA/WEP64/128 WEP multiple data encryption modes to protect user Internet data security. 2.4GHz frequency band: low-frequency signals have a stronger ability to cross obstacles, their signal strength decays more slowly and the transmission distance is longer 5GHz frequency band: fewer existing users, less radio interference, channels are less likely to cause congestion, and are more fluent due to purity Color: black Bluetooth version: 5.4 Gross weight per set: 20g Packing method: bagged Contains per set: 1 driver-free network card, 1 instruction manual Note: Due to the light and screen setting difference, the item's color may be slightly different from the pictures. Please allow slight dimension difference due to different manual measurement.
