一、win7、2000、XP系統
如果系統是XP,那麼就點開始----運行----cmd(然後按確定),然後在提示符下輸入:ipconfig/all(加回車)就可以查出本機MAC地址。如下所示,MAC地址爲:0013-727a-ee61
C:\Documents and Settings\user>ipconfig/all

二、98、NT系統
點開始----運行---winipcfg(然後按確定),會出現一個窗口,上面有MAC地址。暫時找不到98系統的機子,無法出示圖片。
三、用電腦互查
先ping一下對方IP(假設要查10.104.137.25這臺電腦的MAC),然後用arp –a命令。
C:\Documents and Settings\user>ping 10.104.137.25 (ping一下IP爲10.104.137.25的電腦)
Pinging 10.104.137.25 with 32 bytes of data:

10.104.137.25 00-13-72-7a-f0-9e dynamic---------10.104.137.25的MAC地址
10.104.137.254 00-00-5e-00-01-03 dynamic--------網關的MAC地址
登錄192.168.1.1的網絡設置------->DHCP客戶端列表,查看連接過路由器的計算機MAC
懷疑有人偷網,首先你是不是無線路由器,如果是,那你設置只有過濾以下MAC地址通過(填你筆記本無線網卡的MAC地址和臺式機的MAC地址)。如果是普通路由器,不存在有人蹭網的現象,網絡不好你可以電話你網絡的營運商來看看。
