I've just downgraded our AIR-AP1121G-E-K9 Autonomous AP's to LWAPP using WCS 4.2 I cannot get them to register with another controller. I have manually set the AP to use a Primary and Secondary controller, but once reset the AP always connects to the same Controller. I have tried a factory reset on the AP too with the same result. Our other AP's that are purchased LWAPP's work fine! I can move them around six different controllers!!
The problem seems to be with the downgraded AP's They are running 12.4(10b)JA
