Unleashed network disconnects on dashboard after power down

[noel_saldana]

1 out 8 R500 Unleashed AP (only the Master AP) is shown connected on the dashboard after a power down on our area. 
After the power resumes, we noticed that the APs were still broadcasting and service was working fine but they are not showing connected on the Master Dashboard. And also, I cannot ping their IP addresses and only the Master AP was seen when I do a netscan. The LED status of the member APs were blinking on "Power" side.

Any suggestions what to do other than do a manual hard-reset on each APs as they were already place on the ceiling (I cannot ping nor I can do SSH on them as well)?

What happens if you reboot non-Master AP's?

They reconnect to the Unleashed network, no problem.

OK we'll try a soft reset first then if nothing happens then we will do a hard reset as our last option.. 
But hopefully on the next firmware upgrade, this issue would be resolved. Like in case of a power down every access points resume seamlessly.
