Encryption Property Page
Use the
Encryption
property page for configuring WLAN adapter Encryption settings. The
absence of a physical connection makes wireless links vulnerable to information theft. Encryption
is an efficient method of preventing data theft and improving data security. The firmware supports
Open System, 40-bit
and
128-bit
Encryption algorithms.
Use the
Encryption Algorithm
list to select the Open System, 40-bit or 128-bit Encryption
algorithm to be used for the adapter. The default setting is Open System.
Select
Open System
to disable encryption for the WLAN adapter and allow for the transmission
and receipt of data with no security. The Open System algorithm does not encrypt packets over the
network.
To be able to associate and transmit data, an access point and clients must use the same encryption
settings, as summarized below:
If an access point is set to 40-bit encryption and the computer is set to 128-bit encryption, the
devices can associate but no data transmission can occur between the two devices.
