You can't currently access a wlan with a guest access authentication method via a games console.
One suggestion, via
https://support.ruckuswireless.com/answers/000002326 is to create a separate SSID for a gaming network, which is fine, but does anyone have an inclusive list of ip ranges etc to allow through a firewall on such a network?
Another idea is to allow the the console on the guest access network by associating the MAC address of the device with a users guest pass key. Is this at all possible on the Zone Director?
