Forum Thread: Error When Using MITMF

So I've been looking at launching MITM attacks, and started to play around when I discovered this problem
Command I typed
root@kali:~# echo 1 > /proc/sys/net/ipv4/ip_forward
root@kali:~# mitmf --arp --spoof --gateway --target -I wlan0

The attack now seemingly runs, however there is a problem.

When I try to access any website from the victim machine (, I get a timeout error from the browser and eventually this message pops up in the terminal

Error message
"2017-05-18 19:20:41 ARPpoisoner Exception occurred while poisoning Errno 100 Network is down"

Please advise as to what I am doing so badly wrong, many thanks :)
