Choose one of the following Encryption options from the Algorithm
pull-down menu:
• Open Systems (no encryption) - Use the Open System option as the
default setting when no data packet encryption is needed over the
network. Selecting Open System provides no security for the data being
transmitted over the network.
• 40-bit Shared Key - Select 40-bit encryption and enter a 10 Hex digit
(0-1, A-F) encryption key. Use the Reset Keys button to set the encryption
key to the default values.
• 128-bit Shared Key - Select 128-bit encryption and enter a 26 Hex digit
(0-1, A-F) encryption key. The 128-bit encryption option provides a
higher level of security than 40-bit encryption while maintaining an 11
Mbps data rate. Use the Reset Keys button to set the encryption key to
the default values.
The default Hex digit keys are visible any time they are used. As a security
precaution after setting the key values for the network, the digits are replaced
with asterisks *
**
* within the Encryption key fields.
If the associated AP is using a Passkey, the "active" adapter profile is required
to use the same string. The Passkey is a plain text representation of the
WEP keys displayed in the Encryption property page. The Passkey provides an
easy way to enter WEP key data without having to remember the entire 40-bit
(10 character) or 128-bit (26 character) Hex digit string. The Passkey is
case sensitive.
Click the Passkey button to display the Passkey screen. Enter an
easy-to-remember 4 to 32 character string to be used as the WEP algorithm.
Click OK. The MU transforms the Passkey string into a set of four WEP keys
using MD5 algorithms and displays them in the WEP fields. These are the
new WEP keys for the adapter profile. Once displayed in the WEP key fields,
the adapter profile behaves as if the keys were entered manually.
