WPA/WPA2 Encryptions - Advanced Security. As for the security of WI-FI connection, WEP encryption has been no longer the strongest and safest guards for outside intrusions. TL-WN781ND provides WPA/WPA2 encryptions that are created by the WI-FI Alliance industry group, preventing the wireless network from outside threats. Quick Setup Security. Compatible with WI-FI Protected Setup (WPS), TL-WN781ND features Quick Security Setup (QSS) function, which is ideal for creating a WPA encrypted connection to prevent outside intrusion, and meanwhile maximize the management resources. Detachable Antenna. TL-WN781ND offers external antenna that can be rotated and adjusted in different directions to fit various operation environments, and can bring better performance than the internal antenna.
