Kali 2.0 RPi3 Arpspoof Error

[Shonenx33]

hey,

I just installed the official RPi 3 Kali 2 Image. It works fine (except for some wlan interface - wifi only worked if eth0 was plugged in but this one is solved)

As soon as i use arpspoof e.g

arpspoof -i wlan0 -t 192.168.1.14 192.168.1.1

i get this error

libnet_write_link(): only -1 bytes written (Invalid argument)

i think because of this error ettercap and MITMf also fail and i have no idea why...

if i use arpspoof on raspbian it works fine...

edit: if i use arpspoof on eth0 it works fine....and with the default network/interfaces file i cant get wifi without a ethernet cable plugged in...

i hope that someone can help me.
