Instant APs on Central reverting back to

[Normal Guy]

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.

That is not correct behavior and I have not seen that myself.   You should open a case with TAC so they can debug on the Central back-end to see why they got moved into the wrong group after a cold boot.  Did you reset the APs to default after the initial provisioning or did you simply shut them off and turn them back on in the morning?

What the initial setup and testing of the clients connectoivity I just power down all 3 APs and then power them up the very next day.
