Hi,
I have an issue where the 2802i AP are not join the 2504 wlc the firmware is 8.2.151 which is reccomended.
The 2802 get the correct ip and option 43 hex value set correctly to point to the wlc mgmt address but the 2802 are not hitting the controller as my debug capwap events enable show no discovery events from the 2802i.
I have 2600 sitting on the same network and they have no issues seeing the wlc and joining it.
