Currently I'm sitting in Studio A and probably connected to the same AP as the printer in Studio A. If I connect to the Studio A network I can ping the printer in Studio B, but not the printer sitting in Studio A.
Basically, if client IP isolation is turned on and a whitelist is added, I'm unable to ping devices connected to the same IP, but can ping devices on the wired network, and devices on other AP's. Is that the expected behavior? It seems like IP whitelisting should apply to all devices on the network; regardless of whether or not they're on the same AP.
