  - Check the status of the radio's on those AP's through the controller GUI.

Do you mean SSID, not broadcasting, and user device not able to see SSID?

check the AP group has that SSID?

check WLAN config and SSID config might have lost or not saved before power outage ?

[Aziz.zahrani]

Yes i mean that .

and i check AP groups i don’t find any AP there .

How can i add AP to group from GUI ? 

thank you

Choose WLANs > Advanced > AP Groups to open the AP Groups page.

You see add and remove left side added, right side AP available to Add ( AP reboot once you add to AP Group)
