檢視所有網路介面
ls /sys/class/net/
要區分無線網絡卡則可以在
/sys/class/net/$/
下面找 phy80211 或者 wireless 資料夾，無線網絡卡目錄下才存在這些資料夾
通過c函式來檢視：
#include
#include
#include
#include
#include
#include
#include
#include
#include
#include
#include
int device_get_hwinfo(int fd, char* ifname)
return ifr.ifr_hwaddr.sa_family; //this valueint main(int argc, char* ar**)
if_type = device_get_hwinfo(fd, if_name);
printf("%s type is %d\n", if_name, if_type);
return 0;得到網絡卡列表：
#include
#include
#include
#include
#include
int get_if_name(char ifstr[32])
for (i = if_ni; ! (i->if_index == 0 && i->if_name == null); i++)
else
printf("%u: %s\n", i->if_index, i->if_name);
}if_freenameindex(if_ni);
return num;int if_is_wlif(const char * ifname)
for (i = if_ni; ! (i->if_index == 0 && i->if_name == null); i++)
printf("%u: %s\n", i->if_index, i->if_name);
if_freenameindex(if_ni);*/
exit(exit_success);
}檢視裝置下的網絡卡可以通過篩選型別值來判斷網絡卡型別
cat /sys/class/net/eth0/type
1網絡卡型別的值是 1
無線網絡卡 managed和 master模式的值也是 1，當是 monitor模式時值才為 802 或 803

vc 禁用無線網絡卡 禁用網絡卡 禁用有線網絡卡
首先和普通的方法一樣,根據guid禁用網絡卡類裝置,只是在禁用時列舉第i塊網絡卡,讀取其裝置資訊,讀到有 wireless 這個串的就認為它是無線網絡卡,就對它使用禁用操作,否則就接著列舉第i 1塊網絡卡,直到都列舉完.下面給出重要結構.drivedemodlg.cpp implementation...
ubuntu 同時使用無線網絡卡和有線網絡卡
有線連線雷射 無線上外網，sudo route add default gw 30.10.208.1 用處就是上網用外網,pt,印表機,內網windows機器啥的用內網，互不干涉 原來可以這麼簡單 1.有線，無線都連上 ifconfig eth0 eth1 一般來說 eth0 對應有線網絡卡,eth...
電腦無線網絡卡和有線網絡卡同時使用
一 概述 1 需要 由於筆者的無線聯網比有線的速度快，所以連線網際網路要用無線網絡卡。我的虛擬機器橋接與主機溝通，所以需要有線網絡卡連線區域網。2 問題 如果同時連線有線網絡卡和無線網絡卡，因為有線網絡卡的優先順序較高，故僅有線區域網能正常工作，無線網絡卡可連線但卻無法傳送資料。為了讓無線網絡卡工作...
