Looks like you have a vlan trunking issue.  The EAP port must have the non-management vlans as tagged members, and they must also be tagged, and exist on the gateway uplink port as well

 

The EAP doesnt do more than insert a vlan tag to SSID traffic, it will allow devices to connect to any VLAN ID eve if it doesnt exist or isnt on its uplink port.
