AP cannot fully register to WLC - receiving message Slot ID 0 is not valid

Hi guys,

I just migrate an autonomous AP to Lightweight by using WLC. Everything seems to be done correctly except when the AP reset and tried to register to the Controller (the AP reset all the time ...). When I made a "debug lwapp event" on the controller , seems the registering process is OK except this message "Slot ID 0 is not valid for AP ....".

What does it mean ?

What can be the problem ?

Has anybody already got this kind of behaviour ?

Below a copy of the output of the debug on WLC :

Re: AP cannot fully register to WLC - receiving message Slot ID

Reset the AP back to autonomous mode, upgrade the image ,and convert it again. I hope this help may help you.

Re: AP cannot fully register to WLC - receiving message Slot ID

I suspect you are converting an AP that does not have a supported radio onboard. Early model APs could require a AES capable radio upgrade to meet the minimum LWAPP transport requirements. Is your radio a B only or a G radio?
