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 clearing 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. Following
encryption methods are supported by the SpeedTouch™:
The Wired Equivalent Protocol ( WEP )
WPA-Pre Shared Key ( WPA-PSK ).
WEP
The Wired Equivalent Privacy (WEP) algorithm protects wireless communication from
eavesdropping.
WEP relies on a secret key that is shared between the wireless client (e.g. a laptop
with a wireless ethernet card and the SpeedTouch™. The fixed secret key is used to
encrypt packets before they are transmitted. I.e. during transmission between client
and AP ("in the air") the information in the packets is encrypted.
To enable WEP:
1
Select Use WPA-PSK Encryption
2
In the
WEP Key Length
list, click the desired Data Security level (either 64-bit
or 128-bit and Alphanumeric or Hexadecimal).
3
In the
Encryption key
box, type a Network key of your choice. In case of:
64 bits, Alphanumeric
:
The 40-bits Network key must consist of 5 alphanumeric characters.
64 bits, Hexadecimal
:
The 40-bits Network key must consist of 10 hexadecimal digits.
128 bits, Alphanumeric
:
The 104-bits Network key consists of 13 alphanumeric characters.
128 bits, Hexadecimal
:
The 104-bits Network key consists of 26 hexadecimal digits.

Configure your wireless client(s) with the same settings.
The default WEP key and the default WPA key is printed on the
SpeedTouch™ bottom label.
!
Before configuring the SpeedTouch™ encryption, make sure you know
which encryption methods are supported by your wireless client.
If your wireless client(s) supports WPA-PSK we recommend you to use
WPA-PSK, because WEP encryption has been proven to have some security
issues.
