1,As a smart dual-band wireless network card consisting of 2.4GHz and 5.8GHz, you can choose one of the channels freely. Compared with single-frequency wireless network card, it has higher wireless transmission rate with stronger anti-interference. Moreover, the wireless signal is stronger and the stability is higher. 2,By using a new generation of 11AC technology, while you use a wider channel width or higher modulation efficiency in the 5.8G band, its wireless transmission can be up to 866M, which makes watching high-definition video, online games and other network applications more smooth for better audio-visual experience. 3,Wireless network card is suitable for receiving wireless network signals such as WIFI/WLAN for high-speed transmission with stable and smooth performance. 4,Furthermore, this card supports analog for AP function, which is convenient for users to realize multi-person shared network access through network card. 5,Wireless Bluetooth network card with internal and external high-gain smart antenna enhances the strength of the wireless network card to receive and transmit signals, equipped with a 360° detachable rotating antenna, which can effectively extend the distance of receiving and transmitting WiFi. 6,Inserted with the wireless WIFI Bluetooth adapter, for WIN7 / WIN8 / WIN10 system will generally automatically install the relevant driver, which can be inserted directly into the connection for using. If while inserted-in computer which cannot be connected, you shall install the driver for the CD-ROM or cloud-connected link. For XP / VISTA is a driver that must be installed on the CD or cloud disk link.
