Hi,
During the night 2 working APs disconnected from WLC and right now cannot get in back.
I downgreaded software - they connected to WLC get a new one and later cannot find them in WCS (AP are not associated with controller - an error message).
Into logs i can find this message:

I do not use DHCP than Option 43 is not a solution. When i change controller IP to backup ... i can see Ap for a while in controller (wireless tab) but when i click on it , receive message: AP does not exist anymore.
Do you have any idea what happened ? why APs sudenly disconnected from controllers ?
Thank you in advance
