I have had similar problems and I had posted it last month. The CAC tool lacks documentation or its not restoring hte VxWorks configs after the upgrade.
I had tried upgrading few with the CAC and ended up getting up in the celling and connecting the console cable to correct the config settings.
If you want to use the CAC tool,after you download the config ( before the upgrade ti IOS) you have to add the lines User and password and the http server access commands for web-browser access and then continue with the upgrade to ISO.
This seems lenghty if you have upgrade a number of APs.
