Support automatic detection function, can automatically adjust the rate.It can work at both 2.4G and 5G bands at the same time. The 5GHz channel has excellent low interference performance, the 2.4G band can be as high as 300Mbps, and the 5G band can be as high as 867Mbps. Using a simple AP mode and using a card as a AP route, users can realize multiplayer sharing network through wireless network card. The wireless network card also integrates the wireless configuration program and is easy to install. And support AP functionality, allowing you to quickly build a wireless LAN. In wireless security, support WPA/WPA2 / WEP / 802.1x / CD-ROM encryption so that you can quickly implement wireless encryption and secure wireless network security. Wireless transmission rate: support WPA, WPA2 advanced security mechanism, support TKIP, AES, WEP encryption, can provide security for wireless network connection.
