Recover FBF ATA problem!

Hi,
I tried to read the Recover for dummy but I am not able to recover my ATA.
I download the latest firmware from AVM
I configured my network card with
192.168.178.3
255.255.255.0
gw 192.168.178.1

I plug the fritz, within 5 sec I start recover -f frit.image
But I receive
recover: Firmware von fritz.image geladen
recover: Suche fritz!Box
recover: keine Fritz!Box gefuden
recover: error = 1

Please help me.

Thank when I connected the cable to the wlan port I was able to recover the firmware with the frp method.
Thank you
