What are the main components of an Access Point? My APs are damaged, I can fix? You know the major flaws? Transistor, capacitor, inductor, burnt door? The Ruckus provides some support, or lab?
Ruckus AP's don't have any user-serviceable components in the enclosure. You should probably get in touch with support or your local reseller regarding an RMA for your broken AP's.
Of course, electronics are electronics, and if you have enough know-how it's not impossible for one to figure out how to repair some simple problems yourself. But it's unlikely to be as simple as replacing analog parts like you've mentioned.
