PING 50% loss

[kuuhaku]

 Can anyone help me? In this topology, I have 4 different vlans which are marked in color boxes each of which is VLAN. what I want to know is why when doing a ping test from VLAN12 (yellow area) connected to the wireless router to the destination area VLAN 10 (purple area) the result of the ping is 50% loss. does anyone know the cause?

@kuuhaku seems like issue with Ip addressing used in wireless router. when replay packet comes from switch0 to wireless router  some times it forwards it back to switch0 because same network used for wireless router's internet and lan areas. means, switch also keeps laptop MAC in thats table since its form same network. better change lan area to different IP range.
