DescriptionThe table has the following columns:● PortShows the available ports.● Authentication TypeSelect the type of authentication. The selection depends on the operating mode and thetransmission standard.NoteWLAN mode IEEE 802.11 n/acIn WLAN mode IEEE 802.11n/ac, only WPA2 (WPA2-PSK and WPA2 RADIUS) encryptionis possible.– Open SystemThere is no authentication. Encryption with a fixed (unchanging) WEP key can beselected as an option. To use the key, enable "Encryption". You define the WEP key onthe "Keys" page.– Shared KeyIn Shared Key authentication, a fixed key is stored on the client and access point. ThisWEP key is then used for authentication and encryption. You define the WEP key on the"Keys" page.NoteIf you use "Open System" with "Encryption" or "Shared Key", Key 1 must always be seton the "Keys" page.– WPA (RADIUS)Wi-Fi Protected Access (WPA) is a method specified by the Wi-Fi Alliance to closesecurity gaps in WEP. Authentication using a server (802.1x) is mandatory. The dynamicexchange of keys at each data frame introduces further security.– WPA-PSKWPA Pre Shared Key (WPA-PSK) is a weakened form of WPA. In this method,authentication is not carried out by a server but is based on a password. This passwordis configured manually on the client and server.– WPA2 (RADIUS)WPA2 (Wi-Fi Protected Access 2) is a further development of WPA and implements thefunctions of the IEEE 802.11i security standard. However, WPA authentication workswith the RADIUS server.– WPA2-PSKWPA2-PSK is based on the 802.11i standard. However, WPA authentication workswithout a RADIUS server. Instead of this, a WPA(2) key (WPA(2) pass phrase) is storedon each client and access point. The WPA(2) pass phrase is used for authentication andfurther encryption.Configuring with Web Based Management6.10 "Security" menuSCALANCE W1780/W1740 according to IEEE 802.11ac Web Based Management308 Configuration Manual, 11/2019, C79000-G8976-C485-03
