I am trying to do a mitm attack on my own network. I am using Kali linux 2.0 in vmware on a laptop. I used arpspoof -i eth0 -t (VictimIP) (RouterIP) and it started running. However when I tried to browse on the victim machine internet didn't work anymore. This made me draw the conclusion that this had been the case because of using eth0 on a wireless network. Therefore I used a network usb adapter (wlan0). When I used arpspoof again: arpspoof -i wlan0 -t (VictimIP) (RouterIP) it didn't start running but it said: Arpspoof: couldn't arp for host "VictimIP"
I tried several different IP's but it didn't make any difference. I can also say that wlan0 isn't in monitor mode but in managed mode.
Is there anyone who could help me out with this problem?
