I've setup 1 x Controller and and 2 x APs. All of them are Cisco 3802 and all of them have same software 8.5.140.0 and Mobility Express capable. All of the APs are connected to same switch with and same access Vlan. These APs were bench tested and no issue (dis-connecting) found at that time. There were shipped to Melbourne and now after booting, one of the AP has continuously connecting to dis-connecting the Controller. The other AP connected to Controller and has been solid. Same configuration for both APs (client). The AP (in question) doesn't drop from the switch and MAC address is present all the time on the switch port. All the APs have static IPs
Could any of you expert advise what can I try to resolve this. Below are logs

Thanks Leo for the suggestion.
I have two questions here...
- We didn't buy the products with support. Would you think Cisco will still allow me to open case?
- Out of curiosity, if this was bug then wouldn't have affected during initial configuration (bench test phase)?
Thanks
