Thank you for asking this question in the support community. Unfortunately, at the time of this post, the NV16Xs do not support the statistics generated from the show dot11 statistics interface dot11ap <interface> command. Therefore, the output generated from the command is "No available stats for this AP type." The command is intended for the NV150s.
I hope that makes sense, but please do not hesitate to reply to this post with any additional questions or information. I will be happy to help in any way I can.
I went ahead and flagged the "Correct Answer" on this post to make it more visible and help other members of the community find solutions more easily. If you don't feel like the answer I marked was correct, feel free to come back to this post to unmark it and select another in its place with the applicable buttons.
