2 SpeedTouch™ Local Networking Setup

Level 2 This level uses Wi-Fi Protected Access (WPA) to provide state of the art security. This also means that only recent wireless clients will have implemented WPA, and that older wireless clients (without WPA) will not interoperate with the SpeedTouch™580 at this security level.

The WPA standard specifies two modes of operation:

•WPA Personal also know as WPA-PSK (Pre-Shared Key), for residential use.

•WPA Enterprise for business use. In this mode, authentication is done by a dedi- cated authentication server, which is normally not available for residential use. Therefore, the SpeedTouch™580 does not feature WPA Enterprise.

WPA Personal features 3 basic improvements over WEP (security level 1).

1Mutual 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”).

2Stronger encryption, using the Temporal Key Integrity Protocol (TKIP). 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.

3Message Integrity Check (MIC), a strong mathematical function in which the recip- ient 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.

Wireless client Only wireless client adapters compliant to IEEE802.11g and/or IEEE802.11b, will be able requirements to communicate with the SpeedTouch™ and other members of the SpeedTouch™

(W)LAN environment. However, be aware that only IEEE802.11g compliant wireless clients are able to gain full profit of the 54 Mbps (Max) bandwidth delivered by the SpeedTouch™580.

It is highly recommended that wireless client adapters are Wi-Fi™ certified to ensure smooth interoperability with the SpeedTouch™580’s WLAN.
