There are two types of WPA security: WPA Pre Shared Key (without server)
and WPA (with server).
WPA Pre Shared Key uses a so-called pre-shared key as the security key. A
pre-shared key is a password. Each client uses the same key to access the
network. Typically, this mode will be used in a home environment.
WPA (with server) is a configuration when there is a radius server distributes
the keys to the clients automatically. This is typically used in a business
environment.
Network Authentication
802.1x
802.1x anthentication protocol allows users to authenticate into a
wireless network by means of a RADIUS Server. In standard Wi-Fi, 802.1x
authentication is optional but a requirement for WPA.
WPA Pre-Shared Key
This can be from 8 to 40 characters and can be a
combination of letters, numbers, and other characters. This same key must be
used on all of the clients that you set up.
WPA Group Rekey Interval
Rekey interval is how often the keys are
distributed (in packets).
RADIUS Server/Port/Key
Use a RADIUS (Remote Authentication Dial-In
User Service) server to distribute keys to the clients. You also need to
configure RADIUS port and Key. All the clients must set to match these
settings.
Data Encryption (WEP)
WEP (Wired Equivalent Privacy) is a data privacy
mechanism based on a 64-bit or 128-bit shared key algorithm. Wireless device
without a valid WEP key may be excluded from network traffic. Higher
encryption levels offer higher levels of security, but due to the complexity of the
encryption, they may decrease network performance.
Shared Key Authentication

Optional
or
Required
for the sender and
the receiver use a WEP key for authentication.
