We have some AP105 (on ArubaOS 6.1.2.6) in the site that have experienced some problems that some clients (iPhone and Android) getting disconnected immediately once they tried to connect to a specific AP. Checked on the Aruba Controller Web interface and the AP seems to be normal. Once reboot the AP from the web console everything works fine. May I ask is there any proactive way to detect this kind of problem before users complaint that they can't connect to the WiFi network?
