 Rate 
Select a wireless data transmission rate from the drop-

detects and sets the optimum transmission rate. 
 Hidden SSID 
For security purposes, you may choose to hide your

Open System: The sender and the receiver do NOT share 
a secret key. Each party generates its own key-pair and

and agreed upon. 
Shared Key: Authentication is based upon a secret key

WPA Pre-shared key:, The WPA Pre-shared Key 
authentication standard uses a password or “ key” 
between 8 and 32 characters. This encryption key is 
changed after every dialog box using the Temporary Key 
Integrity Protocol (TKIP), which allows users to change 
keys based on dialog box and automatically synchronize 
keys between devices on the network. The TKIP 
encryption algorithm is stricter than the one used by WEP 
but is based on the same standard.
