Do you have more than one AP?  The reason Inask is that the output show that devices have roamed to another AP.  if you have another AP, is it the same model or do you have a mixed environment.  How you contest the AP is to create a test SSID that is open and try to associate. If successful, then next step is to use WPA2/AES psk and test again. You need to create a new SSID for this test. If your device works fine, then you might have to try to verify the psk for the existing SSID or something else, but at least you have done some testing to eliminate the AP or SSID configurations.
