4 Wireless Modifying Virtual Access Point Settings WPA Personal WPA Personal is a Wi-Fi Alliance IEEE 802.11i standard, which includes AES-CCMP and TKIP mechanisms. The Personal version of WPA employs a pre-shared key (instead of using IEEE 802.1X and EAP as is used in the Enterprise WPA security mode). The PSK is used for an initial check of credentials only. This security mode is backwards-compatible for wireless clients that support the original WPA. Table 15 WPA Personal Field Descriptions Field WPA Versions Description Select the types of client stations you want to support: WPA.

If all client stations on the network support WPA2, we suggest using WPA2, as it provides the best security by supporting the IEEE 802.11i standard. WPA and WPA2. If you have a mix of clients, some of which support WPA2 and others which support only the original WPA, select both of the check boxes.

This WPA configuration allows more interoperability, at the expense of some security. 71 Cisco AP 541N Dual-band Single-radio Access Point Quick Start Guide
