Having 3 demo IAP105, they are on the lastest firmware 6.3.1.4-4.0.0.6_44126. After provisioning them into a group , let's call it A-Group, all 3 APs are in joing the group getting all the necessary profile. The very next day when we power up these 3 APs in the customer's network, they all goes back to the default Group. Any idea why is this happening, is it a bug or faulty APs? I havce to move the VC back to A-Group in order for them to work correctly again.
