Therefore, if you don't have an external RADIUS server you should use WPA(2)-
PSK (WPA -Pre-Shared Key) that only requires a single (identical) password
entered into each access point, wireless gateway and wireless client. As long as
the passwords match, a client will be granted access to a WLAN.
6.3.2.2 Encryption
WPA improves data encryption by using Temporal Key Integrity Protocol (TKIP),
Message Integrity Check (MIC) and IEEE 802.1x. WPA2 uses Advanced Encryption
Standard (AES) to offer stronger encryption.
• Use WPA security if you have WPA-aware wireless clients and a RADIUS server.
WPA has user authentication and improved data encryption over WEP.
• Use WPA-PSK if you have WPA-aware wireless clients but no RADIUS server.
• If you don’t have WPA-aware wireless clients, then use WEP key encrypting. A
higher bit key offers better security at a throughput trade-off. You can use
Passphrase to automatically generate 64-bit or 128-bit WEP keys or manually
enter 64-bit or 128-bit WEP keys.
