The SpeedTouch™ supports WPA-PSK which has 3 improvements regarding to WEP:

Authentication via a 4-way handshake to check whether the Pre-Shared Keys (PSKs) are the same.

Stronger encryption types:

Temporal Key Integrity Protocol (TKIP) (default): Instead of using a fixed WEP key, TKIP uses in pairs temporary session keys which are derived from the PSK during the 4-way handshake. For each packet it uses a different key. 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). Which is a strong mathematical function in which the recipient and transmitter each compute and compare the MIC. If they don't match it is assumed that a third person has been trying to read the data.

To enable WPA-PSK:

1Select WPA-PSK Encryption.

2In the WPA-PSK Encryption Key box, type a passphrase (aka Pre-shared key) of your choice. The passphrase must consist of 8 to 63 ASCII characters or 64 HEX digits.

3In the Encryption list, click select the desired Encryption method (either TKIP or AES).

AES is not yet implemented in most clients but AES is implemented in the SpeedTouch™ because it will be the future security standard.

4Optionally select the rekeying interval.

5Click Apply to immediately apply your changes.

6Configure your wireless client(s) with the same settings.

Following modes are available:

New stations are allowed (automatically):

All New stations can access the SpeedTouch™ WLAN.

New stations are allowed (via registration):

Only allowed stations in the Access Control List (ACL) have access. You can add new stations via registration.

For more information, see “ Registering new wireless clients” on page 94

New stations are not allowed:

Only allowed stations in the Access Control List (ACL) have access.

Proceed as follows:

1On the Office Network menu, click Devices.

2Under Pick a task..., click Search for wireless devices.

3The SpeedTouch™ searches for new wireless stations that use the encryption key of the SpeedTouch™ Access Point.

4The SpeedTouch™ takes you to the Office Network. The new station will be shown next to the name of the SpeedTouch™ WLAN.

To view the device settings, click the name of the new station. For more Information, see “6 If needed, reassign server applications to this device.” on page 90.
