AP 2702e I could not get the AP to join it say image not on controller but if I connect it back to 8.2 it loads fine connects fine using ap3g2-rcvk9w8-tar.153-3.JG1.tar
Did Also load the AP Bundle on 8.5
Ideally , if a 2700 AP connects to a WLC running 8.2 image , it must not download the image 153-3.JG1. This AP image is available on 8.6 code. The 8.5 code would download image 15.3(3)JF(x) to the APs.
After associating to the 8.2 WLC , does the AP show the image as ap3g2-rcvk9w8-tar.153-3.JG1.tar ? It should not. That's the recovery image which is the initial image for the AP (before the AP downloads the image from the WLC).
As Flavio said , let's get the output of "show ap bundle all". This output will show if ap3g2 image is present in the WLC bundle or not.
