Encryption Property Page
Use the Encryption property page to set the adapter security level. 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 (no encryption), 40-bit Shared Key (40-bit) or 128-bit Shared Key (128-bit)
encryption algorithms.
Figure 4-11. Encryption Property Page
An access point and an adapter are required to use the same encryption algorithm to
transmit and receive 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. The same is true if the adapter is set for
Open System and the access point is set to 40-bit or 128-bit, no association takes place.
If an access point is set to 40-bit and the adapter is set to 128-bit, the devices can
associate, but no data transmission and reception can take place between the two devices.
