The AP is most likely stuck in boot loop no longer functioning. I recently moved into the house that has this Ruckus hardware and it is the only AP that's dead. The other two are working fine.
I have tried the same thing as this forum member, same problem.
Is the AP still under warranty and how can I get a replacement?
