Under Security following fields are available:
Broadcast Network Name:
By default the SpeedTouch™ broadcasts its network name, allowing you to
easily recognise your wireless network in the list of available networks. Once
you have configured your wireless clients, it is recommended to disable this
feature by selecting this check box.
Allow New Devices:
Allows you to change the access control used by the SpeedTouch™.
Encryption:
Allows you to select an encryption level for your wireless network.
For more information, see

which encryption methods are supported by your wireless client.
Tasks
If you click Details or Configure following task becomes available:
View WDS configuration:

Following encryption methods are supported by the SpeedTouch™:
The Wired Equivalent Protocol (WEP) relies on a secret key that is shared
between the wireless client (for example a laptop with a wireless client) and the
SpeedTouch™. The fixed secret key is used to encrypt data before being
transmitted.
WPA-Pre Shared Key (WPA-PSK) features 3 basic improvements over WEP.
Mutual authentication of access point and client via a 4-way handshake.
In this handshake, both client and access point check whether they share
the same Pre-Shared Key (without sending the PSK "in the clear").
Stronger encryption types:
Temporal Key Integrity Protocol (TKIP) (default): In stead of using a
fixed WEP key, TKIP uses in pairs temporary session keys which are
derived from the PSK during the 4-way handshake. TKIP also
provides a message integrity check (MIC) and a rekeying mechanism
(in seconds).
Advanced Encryption Standard (AES): State-of-the-art encryption;
can only be used if all wireless devices in your WLAN support AES.
Message Integrity Check (MIC), a strong mathematical function in which
the recipient and transmitter each compute and compare the MIC. Non-
matching MICs reveal that a third party has been tampering the data to try
and hack the system.
The default WEP key and the default WPA key is printed on the
SpeedTouch™ bottom label.
