5.2.3
More Secure (WPA(2)-PSK)
The WPA-PSK security mode provides both improved data encryption and user authentication over
WEP. Using a Pre-Shared Key (PSK), both the Device and the connecting client share a common
password in order to validate the connection. This type of encryption, while robust, is not as strong
as WPA, WPA2 or even WPA2-PSK. The WPA2-PSK security mode is a newer, more robust version of
the WPA encryption standard. It offers slightly better security, although the use of PSK makes it
less robust than it could be.

Generate
password
automatically
Select this option to have the Device automatically generate a password. The password
field will not be configurable when you select this option.
Password
The password (WEP key) are used to encrypt data. Both the Device and the wireless
stations must use the same password (WEP key) for data transmission.
If you chose
64-bit
WEP, then enter any 5 ASCII characters or 10 hexadecimal characters
("0-9", "A-F").
If you chose
128-bit
WEP, then enter 13 ASCII characters or 26 hexadecimal characters
("0-9", "A-F").
WEP Encryption
Select
64-bits
or
128-bits
.
This dictates the length of the security key that the network is going to use.

5.2.4
WPA(2) Authentication
The WPA2 security mode is currently the most robust form of encryption for wireless networks. It
requires a RADIUS server to authenticate user credentials and is a full implementation the security
protocol. Use this security option for maximum protection of your network. However, it is the least
backwards compatible with older devices.

Pre-Shared Key
The encryption mechanisms used for WPA(2) and WPA(2)-PSK are the same. The only
difference between the two is that WPA(2)-PSK uses a simple common password,
instead of user-specific credentials.
Type a pre-shared key from 8 to 63 case-sensitive keyboard characters.

Encryption
This field displays the encryption type for data encryption.
If you choose
WPA-PSK
as the security mode, the Device uses
TKIP
for data
encryption.
If you choose
WPA2-PSK
as the security mode and enable WPA-PSK Compatible, the
Device uses either TKIP and AES (
TKIPAES MIX
) for data encryption.
If you choose
WPA2-PSK
as the security mode but disable WPA-PSK Compatible, the
Device uses
AES
for data encryption.

The WPA security mode is a security subset of WPA2. It requires the presence of a RADIUS server
on your network in order to validate user credentials. This encryption standard is slightly older than
WPA2 and therefore is more compatible with older devices.
