yes indeed can ping from PC, and not from controller.
connecting via SSH GW is reachable but not the controller.
doing the same on other AP gives me ping on both GW and Controller.
is there something missed on the Ports?
back again with some findings and details for you.
the AP was set back to factory setting to enable a proper start
Controller static IP was set on the AP -- 10.100.10.70/24
AP static IP was set -- 10.100.10.78/24
