Welcome to Cisco Support Community. We would love to have your feedback.

we are about to setup a bunch of N accesspoints Cisco 1252 AP.
What is the recommended image to use on the wlc to get the best stability, least bugs and highest functionality?
I would recommend to go the latest version from series 5:
5-2-193-0.aes as the main image and 5-2-157-0-ER.aes as the emergency image.
It s stable in everything I tested personnally.
