Hi
I assume you have provisioned the AP's in a AP group with at least one VAP.
Are there any flags related to the AP in the AP Installation overview?
The controller needs to be upgraded to 6.4, but i assume this is done, otherwise you would not be seeing the AP's.
I have witnessed something somewhat similar. In my installation, the DNS domain for the AP was different from what the aruba-master DNS record was showing.
I'm now assuming you are using DNS as the primary solution for the AP to get hold of the controller.
My AP-205 was experiencing much of the same when the DNS domain was wrong. The AP stayed up for longer or shorter periods, but giving med ID flags.
