Ftp over WiFi

Please help me Ftp to my dm800 SE over WiFi. My dcc or filezila can`t see my dreambox over WiFi but no problem over the Lan. All settings in dreambox seams ok when i run network test all comes green and i get my ip address, subnet mask, pimary gateway and dns server. And when i log in to my rooter i can see dreambox connection but dcc just can`t see it when i run search and does not connect when entering ip address manually. Thanks
