Authentication -The default is set to Auto, so it will auto-detect for Shared Key or Open System authentication. For Shared Key authentication, both the sender and the recipient share a WEP key for authentication. For Open System authentication, the sender and the recipient do not share a WEP key for authentication. If you are not sure which authentication method to select, keep the default, Auto.

wpa (wi-fi protected access): a wireless security protocol using TKIP (Temporal Key Integrity Protocol) encryption, which can be used in conjunction with a RADIUS server.

wpa2 offers a stronger encryption than wpa by using the AES (Advanced Encryption Standard) which is a block cipher with block sizes of 128, 192 or 256 bits.

WPA Personal

WPA Personal offers two encryption methods, TKIP and AES, with dynamic encryption keys. WPA2 only uses AES for encryption. Select TKIP or AES for encryption for WPA Personal. Then enter a Passphrase that is 8-63 characters in length.

Encryption - Select the type of algorithm you want to use, TKIP or AES, from the Encryption drop-down menu.

Passphrase - Enter a Passphrase, also called a Pre-shared Key, of 8-63 characters in the Passphrase field.

Click the Next button to continue or the Back button to return to the previous screen.
