The AP is joined, all I would like to do is upgrade the boot version this accesspoint has been converted from autonomous to lwapp, but we buy new ones with the lwapp(rcv ios) and their boot versions are different
You can't upgrade the boot version of the AP. Like the other post mentioned, the WLC manages the firmware of the ap's that joined it. You have to understand that since your ap's were converted to lwapp doesn't mean that it should have the same boot as an original lwapp. Also, are the ap's the same model?
