I'm experiencing issues with the Samsung model Chrome book and the ZF7363's. Placed a case id to evaluate the config/situation. It's not an issue with connecting to the SSID but when 19 of the Chromebooks connect and use the internet is where the performance starts degrading rapidly. My macbook pro is connected via WiFi to the same AP and not 1 packet drops or goes above 30ms.
