Linux下无线网卡的安装 用lsusb查看USB的安装情况,如下图
使用yum安装 已经成功安装
查看无线网卡
进入到cd /lib/modules/2.6.32-431.el6.i686/kernel/drivers/net/ wimax/wireless/查看无线网卡版本 [iyunv@host2 net]# lsusb Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub Bus 002 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub Bus 002 Device 002: ID 0e0f:0003 VMware, Inc. Virtual Mouse Bus 002 Device 003: ID 0e0f:0002 VMware, Inc. Virtual USB Hub Bus 001 Device 002: ID 148f:3070 Ralink Technology, Corp. RT2870/RT3070 Wireless Adapter 根据已有的驱动,把驱动拷到linux下
然后编译安装驱动 查看无线网卡有命令iwconfig [iyunv@host2 rtl]# iwconfig -bash: iwconfig: command not found 提示没有这个指令 需要安装无线网卡工具 [iyunv@host2 rtl]# cd /media/cdrom/Packages/ [iyunv@host2 Packages]# ll |grep -i wireless -r--r--r--. 2 root root 94584 Jul 3 2011 wireless-tools-29-5.1.1.el6.i686.rpm -r--r--r--. 2 root root 95848 Jul 3 2011 wireless-tools-29-5.1.1.el6.x86_64.rpm [iyunv@host2 Packages]# yum install wireless -y 现在可以使用iwconfig查看无线网卡设置了 [iyunv@host2~]# iwconfig lo no wireless extensions. eth0 no wireless extensions. wlan0 unassociated Nickname:"rtl_wifi" Mode:Auto Access Point: Not-Associated Sensitivity:0/0 Retry:off RTS thr:off Fragment thr:off Encryption key:off Power Management:off Link Quality=0/100 Signal level=0 dBm Noise level=0 dBm Rx invalid nwid:0 Rx invalid crypt:0 Rx invalid frag:0 Tx excessive retries:0 Invalid misc:0 Missed beacon:0 无线网卡wlan0已经出现了 现在将我们的wlan0启动 [iyunv@host2 ~]# ifconfig wlan0 up 搜索无线网络 [iyunv@host2~]# iwlist wlan0 scanning 你会看到你附近能搜索的无线网列表 [iyunv@host2 rtl3037]# iwlist wlan0 scanning wlan0 Scan completed : Cell 01 - Address: A8:57:4E:78:A4:02 ESSID:"NET-1" Protocol:IEEE 802.11bgn Mode:Master Frequency:2.437 GHz (Channel 6) Encryption key:on Bit Rates:300 Mb/s Extra:wpa_ie=dd160050f20101000050f20401000050f20401000050f202 IE: WPA Version 1 Group Cipher : CCMP Pairwise Ciphers (1) : CCMP Authentication Suites (1) : PSK Extra:rsn_ie=30140100000fac040100000fac040100000fac020000 IE: IEEE 802.11i/WPA2 Version 1 Group Cipher : CCMP Pairwise Ciphers (1) : CCMP Authentication Suites (1) : PSK IE: Unknown: DD310050F204104A00011010440001021047001000000000000010000000A8574E78A402103C0001011049000600372A000120 Signal level=23/100 Cell 02 - Address: F8:D1:11:FB:F6:D4 ESSID:"php-1" Protocol:IEEE 802.11bgn Mode:Master Frequency:2.437 GHz (Channel 6) Encryption key:on Bit Rates:300 Mb/s Extra:wpa_ie=dd160050f20101000050f20401000050f20401000050f202 IE: WPA Version 1 Group Cipher : CCMP Pairwise Ciphers (1) : CCMP Authentication Suites (1) : PSK Extra:rsn_ie=30140100000fac040100000fac040100000fac020000 IE: IEEE 802.11i/WPA2 Version 1 Group Cipher : CCMP Pairwise Ciphers (1) : CCMP Authentication Suites (1) : PSK IE: Unknown: DD0E0050F204104A0001101044000102 Signal level=23/100 到这一步已经可以找到无线网了 想要连接无线网还需要安装一个wpa工具 进入系统光盘查看与wpa相关的软件包 [iyunv@host2 rtl3037]# cd /media/cdrom/Packages/ [iyunv@host2 Packages]# ll |grep -i wpa_supplicant -r--r--r--. 2 root root 374368 Feb 4 2013 wpa_supplicant-0.7.3-4.el6_3.i686.rpm 安装这个软件包来连接 [iyunv@h2ost Packages]# yum install wpa_supplicant -y 安装好后用 wpa_passphrase来设置无线网的名称和密码 格式是 wpa_passphrase <SSID> [password] [iyunv@host2 Packages]# wpa_passphrase NET-1 # reading passphrase from stdin 123!@#qaz network={ ssid="NET-1" #psk="123!@#qaz" } 设置好后就可以连接了 连接用 wpa_supplicant 命令 [iyunv@host2]# wpa_supplicant -B -i wlan0 -D wext -c /etc/wpa_supplicant/wpa_supplicant.conf -B 后台运行 -i 选择网卡 -D wext -c 配置文件地址 动态获得IP地址 [iyunv@host2 Packages]# dhcpclient wlan0 编辑开机脚本 [iyunv@lhost2 Packages]# vim /etc/rc.d/rc.local 在末尾添加以下3条命令 modprobe 3037u wpa_supplicant -B -i wlan0 -D wext -c /etc/wpa_supplicant/wpa_supplicant.conf dhcpclient
