4.3.2 Security submenu. Security settings
Use this menu to configure general data encryption settings for a wireless network. The client wireless
equipment can be configured either manually or automatically with the help of WPS.
WPS (Wi-Fi Protected Setup)—a standard developed by Wi-Fi Alliance to simplify setup of wireless
networks. The technology allows quick, secure, and simple setup of a wireless network without having in-depth
knowledge of Wi-Fi technology and encryption protocols. WPS automatically sets the network name and
configures data encryption to protect the network from unauthorised access. These operations should be
manually done without WPS.
In order to establish a connection, user simply needs to press the WPS button located on the side panel of
the device or use web configuration to enter PIN code.
WPS Setup
– Enable WPS – to enable WPS access, select Enable from the drop-down list, if WI-FI network adapter of
your device supports this configuration mode
– Set WPS AP mode—sets WPS mode of the access point
Shortcomings of WPS
Wi-Fi routers supporting the WPS technology have a security vulnerability. This vulnerability allows
attackers to retrieve passwords for WPA and WPA2 encryption protocols. The technology is
vulnerable as it allows to brute-force the 8-digit network key (PIN).
Access point manual configuration:
– Select SSID—selects a name of a wireless network from the list
– Network Authentication—selects a network authentication mode from the drop-down list:
– Open—wireless network security features are disabled (in this mode, only WEP key can be used)
