Use the Encryption tab for configuring 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 and Shared Key (40-bit) 
Encryption algorithms.

MicroAP Authentication Options A MicroAP can use Open System, Shared Key or both. If Shared Key 
is enabled and Open System is not, the MicroAP grants access to adapters that have Shared Key 
enabled and are using the correct Encryption Key algorithm. 

Adapters using Open System cannot associate to the MicroAP when the MicroAP has Shared Key 
enabled. Only when the MicroAP is using Open System can Open System mobile computers associate 
to it.
