    Hello Atul,
    The most common cause for this issue is iptables, maybe there’s a rule there that is preventing the connection, please run the following command to remove any rules that might be preventing this from working:

    iptables --flush
    iptables --table nat --flush
    iptables --delete-chain
    iptables --table nat --delete-chain
    iptables -P FORWARD ACCEPT

    Then follow the steps shown again.
    Also please make sure you are using the right interfaces when following the steps.

    Hello sir,
    I followed exactly same steps as you told in video lectures.Although i created fake AP but i am unable to give internet service to it.As a result whenever any device connects to my fake AP,it does not have any internet service in it.
    1. Host connected to my fake AP is not directed to my server’s index.php.Rather an error is shown on his screen that ‘site can’t be reached’
    2.UNABLE TO RESTART dnsmasq (unable to run : dnsmasq -C <dnsmasq.conf file path>)2nd time after running ones.I face the following error whenever i edit dnsmasq.conf file and try to run same command again:

    ERROR : dnsmasq: failed to bind DHCP server socket: Address already in use

    *For now i need your help primarily to provide internet access to client connected to my fake AP
    PS: I used exactly same conf file and same ip granting commands that you used to created fake AP.

    Can you please show me the result of ifconfig BEFORE starting the fake AP, and can you please show me the config files you’re using?

    I was most interested in seeing the values for wlan0, why did it not show up when you ran
    ifconfig
    ??

    There happened some error, sir, I apologize for that error. Here is the result of ifconfig when I plugged in the adapter after starting the machine:

    #after this I followed the same procedure as I described in another topic. Everything works fine, target pc is able to connect my fake AP, able to browse my localhost 192.168.1.1 index.php, but explicitly by typing 192.168.1.1 in the URL

    Hello Zaid sir,
    I just want to tell you that I moved a step ahead and I wish I could solve rest of my problem myself. I will get back to you if I face any further obstacle.
    Thanks a lot for your assistance.
