I work with am5728-evm and I want to test wireless connection.

    Hi Saman,

    I suggest you to do few steps to investigate your issue:
    1. Ping the IP address of the gateway. If you are not sure for IP gateway you can check it using "route -n" command.
    If you ping IP gateway successfully you should go to next step. If ping IP gateway fails you have an issue with network (WiFi) connectivity.
    2. As you pinging www.google.com you should check your DNS configuration executing
    cat /etc/resolv.conf
    You should verify whether nameserver IP address is real DNS server and try to ping it.
    If there is no nameserver (DNS) configuration you can configure it as follow description at:
