linux上网问题？无线网卡怎么被识别成有线网卡

用ifconfig -a查看有一个名字为enp0s2的网卡

$jwid=$_POST['jwid'];
$jwpw=$_POST['jwpw'];
$jwsc=$_POST['jwsc'];

$isLogin = getLogin($jwid,$jwpw,$jwsc);

if ($isLogin=="yes") {
session_start();
$xuenia = getXueNian($jwid);
$scoreArry = array();

for ($i=0; $i < count($xuenia); $i++) {    //每个学年两个学期
    $scoreArry[] = get_td_array(getGrade($jwid,$xuenia[$i],"1"),"1");
    $scoreArry[] = get_td_array(getGrade($jwid,$xuenia[$i],"2"),"2");
}

// $s=getGrade($jwid,$xuenia[$i],"2");

// $_SESSION['name']=getName($s);
// $_SESSION['college']=getCollege($s);
$_SESSION['course']=getcoursecontent(getcourse($jwid));
$_SESSION['score']=$scoreArry;
Header("Location:show.php"); 

}else{
session_start();
$_SESSION['error']="errorLogin";
header("Location:index.php");
}

?>

不好意思下面的代码请无视
