For single AP ->
Go to AP/Devices list -> drill down to folder that has the AP in it (don't drill to the AP itself) -> on the list table, click the Pencil icon on the top right -> check the checkbox next to the AP -> at the top, choose the option to run report -> then select either an existing report definition to use as a template, or create a new report definition.
For multiple APs ->
rinse and repeat the above steps, but make sure the list view includes all the APs. You might try customizing the list view to include 'Floor' to show which APs are on which floor plan to make it easier.
