Converting from WEP/CKIP/CMIC to WPA

When configuring WEP with CKIP/CMIC, broadcast key rotation had to be selected separately within the AP configuration. Does WPA by default include broadcast key rotation or do I have to configure it?

Also, is it beneficial to select any of the values under “WPA Group Key Update”: “Enable Group Key Update On Membership Termination” and “Enable Group Key Update On Member's Capability Change”? I’m having difficulty finding any documentation that explains these values in detail.

Any help is greatly appreciated.

Re: Converting from WEP/CKIP/CMIC to WPA

Broadcast key rotation (also known as Group Key Update)Broadcast Key Rotation allows the access point to generate the best possible random group key and update all key-management capable clients periodically. Broadcast Key rotation does not work for clients running static WEP. Wi-Fi Protected Access (WPA) also provides additional options for group key updates. See the "Using WPA Key Management" section for details on WPA.
