Parameter description
It specifies the personal or pre-shared key security mode.
−
WPA-PSK: It indicates that the wireless network corresponding to the
selected SSID is encrypted with WPA-PSK.
−
WPA2-PSK: It indicates that the wireless network corresponding to the
selected SSID is encrypted with WPA2-PSK.
−
Mixed WPA/WPA2-PSK: It indicates that wireless clients can connect to the
wireless network corresponding to the selected SSID using either WPA-PSK
or WPA2-PSK.
It specifies the encryption algorithm corresponding to the selected security
mode. If Security Mode is set to WPA-PSK, this parameter can be set to AES and
TKIP values. If Security Mode is set to WPA2-PSK or Mixed WPA/WPA2-PSK,
this parameter can be set to AES, TKIP, and TKIP&AES values.
−
AES: It indicates the Advanced Encryption Standard.
−
TKIP: It indicates the Temporal Key Integrity Protocol. If TKIP is used, the
maximum wireless throughput of the AP is limited to 54 Mbps.
−
TKIP&AES: It indicates that both TKIP and AES encryption algorithms are
supported. Wireless clients can connect to the wireless network
corresponding to the selected SSID using TKIP or AES.
It specifies a pre-shared WPA key, that is, the password clients use to connect to
the wireless network.
It specifies the automatic update interval of a WPA key for data encryption. A
shorter interval results in higher data security.
The value 0 indicates that a WPA key is not updated.

WPA, WPA2
To address the key management weakness of WPA-PSK and WPA2-PSK, the WiFi Alliance puts
forward WPA and WPA2, which use 802.1x to authenticate clients and generate data
encryption–oriented root keys. WPA and WPA2 use the root keys to replace the pre-shared
keys set manually, but adopt the same encryption process as WPA-PSK and WPA2-PSK.
WPA and WPA2 uses 802.1x to authenticate clients and the login information of a client is
managed by the client. This effectively reduces the probability of information leakage. In
addition, each time a client connects to an AP that adopts the WPA or WPA2 security mode,
the RADIUS server generates a data encryption key and assigns it to the client. This makes it
difficult for attackers to obtain the key. These features of WPA and WPA2 help significantly
increase network security, making WPA and WPA2 the preferred security modes of wireless
networks that require high security.
