802.11无线网卡驱动(80211无线网卡驱动是什么)
一、无线网卡高级配置里面的,这个是什么意思,每一个的意思是
1、802.11b preamble:是802.11b帧的前导域，用于设备之间的数据同步。
2、Adhoc 11n：Adhoc是一种不依赖与基础设备而组网的一种技术，节点与节点之间互相承担路由转发和广播等功能。
3、Dynamic MIMO power save：动态电源调节技术。
4、network address:就是网卡的MAC地址，默认为空，可以修改为其他的MAC地址。
5、receive buffers:网卡最大可用的接收缓存。
6、scan valid interval:扫描间隔，保持默认即可。
7、transmit buffers:网卡最大可用的发送缓存。
二、无线网卡驱动英特尔 Wireless-N 7260 for linux
1.首先确定电脑的无线芯片是什么型号的，用如下命令：
lspci-vnn|grep 14e4
0c:00.0 Network controller [0280]: Broadcom Corporation BCM4312 802.11b/g [14e4:4315](rev 01)
BCM4312就是用的无线芯片的具体型号了。
2.在broadcom的网站上下载linux下的驱动。www.broadcom.com/support/802.11/linux_sta.php。下了32-bit的驱动，再下了一个readme。然后基本上按照这个readme来安装驱动。要跟据机子的位数来下载.
3安装可参照：
1）.安装：先创建驱动程序的目录，mkdir hybrid_wl
cd hybrid_wl
将驱动程序解压到该目录中，tar-xzf hybrid-portsrc-x86_64-v5.10.91.9.3.tar.gz
2）.然后执行下面的命令：
make clean
make
移除原来的驱动程序，
lsmod| grep"b43\|ssb\|wl"
rmmod b43
rmmod ssb
rmmod wl
3）.真正的安装
modprobe lib80211
insmod wl.ko
4.完成
安装中有问题请联系我。E-mail：hou.ge1999@163.com
三、瑞昱RTL 8187L无线网卡linux驱动
应该是想在LINUX下使用8187无线网卡。那么只要达到目的就行。
拿8187的WINDOWS下的驱动，使用ndiswrapper这个桥梁程序，把驱动借到linux下用，换句话说就是内核先调用ndiswrapper模块，ndiswrapper模块再调用无线网卡在WIN下的驱动。
详细步骤如下，我在我的本本上成功的驱上了我的无线网卡，我把过程记录下来了，现在贴给你，希望对你有帮助。

《Linksys WPC54Gv2的PCMCIA无线网卡在centos5.3下能用了》
问题：CENTOS_5.3安装好后在设备管理器里能看见无线网卡，但无法激活
使用lspci可以看到这个无线网卡
[root@ljj~]# lspci
............
03:00.0 Network controller: Broadcom Corporation BCM4306 802.11b/g Wireless LAN Controller(rev 02)
参考lex在和mjwdj在上的方法解决了问题
解决办法：
1、去下载ndiswrapper-1.55.tar.gz，它是一个桥梁，能使windows下的无线网卡驱动在Linux下使用。
2、tar xvzf ndiswrapper-1.55.tar.gz解开它
3、less INSTALL看安装说明，先make uninstall，再make，再su为root超级用户后make install安装它。
4、把windows下的无线网卡驱动解开，我的网卡是PCMCIA接口的linksys WPC54Gv2，解开后运行
[root@ljj~]#/usr/sbin/ndiswrapper-i lsbcmnds.inf
5、安装后看看是否安装上了
[root@ljj~]#ndiswrapper-l
lsbcmnds: driver installed
device(14E4:4320) present(alternate driver: bcm43xx)
6、再看看14E4:4320也在，是那个rev 02的版本
[root@ljj~]# lspci-n
00:00.0 0600: 8086:3575(rev 04)
00:01.0 0604: 8086:3576(rev 04)
00:1d.0 0c03: 8086:2482(rev 02)
00:1d.1 0c03: 8086:2484(rev 02)
00:1d.2 0c03: 8086:2487(rev 02)
00:1e.0 0604: 8086:2448(rev 42)
00:1f.0 0601: 8086:248c(rev 02)
00:1f.1 0101: 8086:248a(rev 02)
00:1f.3 0c05: 8086:2483(rev 02)
00:1f.5 0401: 8086:2485(rev 02)
01:00.0 0300: 5333:8c2e(rev 05)
02:00.0 0607: 104c:ac51
02:00.1 0607: 104c:ac51
02:02.0 0780: 11c1:0449(rev 01)
02:08.0 0200: 8086:1031(rev 42)
03:00.0 0280: 14e4:4320(rev 02)
7、看看无线网卡接口
[root@ljj~]# iwconfig
lo no wireless extensions.
eth0 no wireless extensions.
sit0 no wireless extensions.
eth1 IEEE 802.11b/g ESSID:"" Nickname:"Broadcom 4306"
Mode:Managed Frequency=2.442 GHz Access Point: Invalid
RTS thrff Fragment thrff
Encryption keyff
Link Quality=0/100 Signal level=-256 dBm Noise level=-256 dBm
Rx invalid nwid:0 Rx invalid crypt:0 Rx invalid frag:0
Tx excessive retries:0 Invalid misc:0 Missed beacon:0
发现没有ESSID号，没有连接速率，没连上。
8、把它变成模块
[root@ljj~]# ndiswrapper-m
adding"alias wlan0 ndiswrapper" to/etc/modprobe.d/ndiswrapper...
9、lsmod发现系统本身有bcm43xx，这也就是为什么在设备管理器中能看到无线网卡的原因，但它不能用，所以要删掉这个模块改用ndiswrapper
[root@ljj~]# modprobe-r bcm43xx
10、再加载ndiswrapper模块让它负责用windows下的驱动程序驱动无线网卡
[root@ljj~]# modprobe ndiswrapper
再用lsmod看看，仅有ndiswrapper模块了
[root@ljj~]# lsmod
Module Size Used by
ndiswrapper 170256 0
............
11、指定无线信号源，使用
[root@ljj~]# iwconfig eth1 essid'ljj'
12、指定密码
[root@ljj~]# iwconfig eth1 key 6666-6666-66 open
如果要开机就用可以直接在rc.local文件里设定：
echo'iwconfig eth1 key 6666-6666-66 open'>>/etc/rc.d/rc.local
13、指定ip地址
[root@ljj~]# ifconfig eht1 192.168.1.10 netmask 255.255.255.0
[root@ljj~]# ifconfig eth1 up
15、指定网关、缺省路由
[root@ljj~]# route
Kernel IP routing table
Destination Gateway Genmask Flags Metric Ref Use Iface
192.168.1.0* 255.255.255.0 U 0 0 0 eth1
169.254.0.0* 255.255.0.0 U 0 0 0 eth1
[root@ljj~]# route add default gw 192.168.1.1 eth1
[root@ljj~]# route

default 192.168.1.1 0.0.0.0 UG 0 0 0 eth1
16、就可以用了，你还可以扫描一下周围的其他网络信号
[root@ljj~]# iwlist eth1 scanning
