The documented recommendation for using the Network.WLAN.FusionPublic settings has been that the "Persist Across Cold Boot" option should NEVER be set to TRUE. The only reason this option was ever included in the first place was for backwards compatibility with the original 2.x API. Engineering recommends using WLAN settings which are NOT cold boot persistent. If a user has a REAL need for the Fusion WLAN settings to be cold boot persistent, the recommended way is to deploy the WLAN settings in a bundle (not in the profile settings). For more details about this recommendation, see Ch5 in the Understanding MSP 331 documentation.
