You need to request permission in manifest :

and request it in your activity :

    private void grantPermm()
{

    try
    {
        if (ContextCompat.checkSelfPermission(MainScreenActivity.this,
                  Manifest.permission.ACCESS_FINE_LOCATION) == PackageManager.PERMISSION_GRANTED)

        {

        }
        else
        {

            ActivityCompat.requestPermissions(MainScreenActivity.this,
                    new String[]{Manifest.permission.ACCESS_FINE_LOCATION},
                    101);
        }

    }
    catch (Exception xx){}

}

then use this function :

    public  static String  getWifiName(Context context)
{
    String result="";
    try {
        WifiManager manager = (WifiManager) context.getSystemService(Context.WIFI_SERVICE);
        if (manager.isWifiEnabled())
        {
            WifiInfo wifiInfo = manager.getConnectionInfo();
            if (wifiInfo != null)
            {
                NetworkInfo.DetailedState state = WifiInfo.getDetailedStateOf(wifiInfo.getSupplicantState());
                if (state == NetworkInfo.DetailedState.CONNECTED || state == NetworkInfo.DetailedState.OBTAINING_IPADDR)
                {
                    result = wifiInfo.getSSID();
                    if(result.equalsIgnoreCase(""))
                    {
                        Toast.makeText(context,"You are connected to mobile data", Toast.LENGTH_SHORT).show();
                        result="";
                    }

                    return result;
                }
                else
                {
                    Toast.makeText(context,"WIFI not connected", Toast.LENGTH_SHORT).show();
                    return "";
                }
            }
            else
            {
                Toast.makeText(context,"No WIFI Information", Toast.LENGTH_SHORT).show();
                return "";
            }
        }
        else
        {
            Toast.makeText(context,"WIFI not enabled", Toast.LENGTH_SHORT).show();
            return "";
        }
    }
    catch (Exception xx)
    {
        Toast.makeText(context, xx.getMessage().toString(), Toast.LENGTH_SHORT).show();
        return "";
    }
}
