    I have been working around the Evil Twin Airbase-ng for quite a while and i am unable to get my victim PC which is my other windows 10 machine to connect; It did connect to the AP once(rarely) and when it did it had no internet connect which has kept me up for sometime, i am going to post the proccess i have performed please go through them and guide me through the issue.

    Note:i have tried iptables and echo 1 it didnt help
