Wireless Access

Our APs in a particular group go offline over night consistently? We have 3 APs in our Athletics group and sometime during the night or early morning the APs go offline and don't come back up. They show green lights but users can't connect to them. I've tried different firmware and 2 different AP models 2 655 and 1 555, the 655s are connected to 1 aruba switch and the 555 is connected to a cisco switch,the switches shows that the devices are up and rebooting the switches will bring the APs back online. We see no blocked connections on the firewall as well along with no viable information the events just says ap went offline. 

-------------------------------------------

what Aruba switch you have to power up the AP-655s? 

also have you enabled IPM for the APs? 

Lastly when the APs are in that state, can you console to one of them?

655 and 555 are quite power hungry. If you only have a CLASS 4 PoE, then you need two ethernet interfaces to power it for normal operation.

What can you see from show tech-support logs?

since you are  using Aruba Central , it should provide additional info like the cause of reboot and perhaps other alerts.
