A.4.3 Encryption Property Page
Use the Encryption property page to set the adapter profile security level.
The firmware supports Open System (no encryption), 40-bit Shared Key
(40-bit), 128-bit Shared Key (128-bit) and Kerberos encryption algorithms.
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 access point and the adapter are required to use the same encryption
algorithm to associate and transmit data. If an access point is set to Open
System and an adapter is set to 40-bit or 128-bit, no association takes place.
Similarly, if an adapter is set to Open System and an access point is set to
40-bit or 128-bit, no association takes place.
If an access point is set to 40-bit and an adapter is set to 128-bit the adapter
can associate to the access point, but no data transmission can take place.
