I have Enterasys AP 3605. I approved it and it was working fine last week. This week, the controller says it's down. The AP is plugged in, but blinking red and green. Does anyone know what caused the AP to go down? I checked the log and it said poll timeout, but I have had other APs do that and come back up by releasing them from the backup controller. I tried rebooting it remotely, but that didn't do anything, and it's not active in the backup controller.
