123.2.3.2 WPA/WPA2 EncryptionWi-Fi Protected Access (WPA) is an encryption method for WLAN. WPA contains the WEP architecture, but offers additionalprotection via dynamic codes, which are based on the Temporal Key Integrity Protocol (TKIP), and also offers pre-shared keys(PSK) or extensible authentication protocol (EAP) for user authentication. However, a radius server is required for this. WPA2 is adevelopment of WPA and uses a different encryption algorithm, advanced encryption standard (AES).Select WPA Pre-shared Key under Encryption. Then, under WPA Unicast Cipher Suite, select WPA (TKIP) or WPA (AES).Then you must select the Pre-shared Key Format. Selecteither Passphrase for a key with a length of at least 8 andmax. 63 characters, whereby letters (A-Z), numbers andpunctuation marks can be used, or Hex for a 64 characterkey, in which only numbers from 0-9 andletters from a-f can be used. The next step is entering akey, called a pre-shared-key (PSK). All clients which are toaccess the access point must know this character string.Click Apply to save your settings. You must then restart therouter for the settings to take effect. To do so, click Apply inthe next window. The wireless network with encryption isavailable after you restart.3.2.4 WPS Automatic configurationWPS (WiFi Protected Setup) is a function that makes the security configuration of the Wireless LAN connection easier. In order to beable to use the function, the router/access point and the remote station (WLAN USB stick, PCI card or PCMCIA card) must have theWPS function. To carry out the security configuration, proceed as follows:The router/access point specifies which encryption and which key is used. The encryption entered here applies to all users of thenetwork.There are two methods:a) Confi guration using the buttonPress the WPS button on the router/access point. Within two minutes, you must press the PBC button on the WPS tab page inthe WLAN adapter’s configuration program. The connection is now established automatically.b) Pin codeMake a note of the pin code, which is displayed in the WLAN adapter’s configuration program. Select the target network in theupper list and then click PIN. Switch to the user interface of the router. If your router supports this method, you will find an entryfi eld for the pin code in the WPS settings. Enter the code you noted earlier and start the transmission. The connection is nowestablished automatically.If the connection is successful, a profile is created, which is restored automatically when you reconnect.
