Select the type of authentication. The selection depends on the operating mode and the
transmission standard.
–
There is no authentication. Encryption with a fixed (unchanging) WEP key can be
selected as an option. To use the key, enable "Encryption". You define the WEP key
on the "Keys" page.
–
In Shared Key authentication, a fixed key is stored on the client and access point. This
WEP key is then used for authentication and encryption. You define the WEP key on
the "Keys" page.
–
Wi-Fi Protected Access is a method specified by the Wi-Fi Alliance to close security
gaps in WEP. Authentication using a server is stipulated (802.1x). The dynamic
exchange of keys at each data frame introduces further security.
Note
Make the relevant RADIUS settings initially on the page "Security > WLAN > Client
Radius Supplicant".
–
WPA Pre Shared Key (WPA-PSK) is a weakened form of WPA. In this method,
authentication is not established by a server but is based on a password. This
password is configured manually on the client and server.
–
WPA2 (Wi-Fi Protected Access 2) is a further development of WPA and implements
the functions of the IEEE 802.11i security standard. WPA authentication works,
however, without the RADIUS server.
Note
Make the relevant RADIUS settings initially on the page "Security > WLAN > Client
Radius Supplicant".
–
WPA2-PSK is based on the 802.11i standard. WPA authentication works, however,
without a RADIUS server. Instead of this, a WPA(2) key (WPA(2) pass phrase) is
stored on each client and access point. The WPA(2) pass phrase is used for
authentication and further encryption.
–
Setting with which an access point can process both the "WPA-PSK" as well as the
"WPA2-PSK" type of authentication. This is necessary when the access point
communicates with different clients, some using "WPA-PSK" and others "WPA2-PSK".
The same encryption method is set on the clients.
–
Setting with which an access point can process both the "WPA" as well as the "WPA2"
type of authentication. This is necessary when the access point communicates with
