你會發現不能安裝，這是因為沒有開發環境

[root@CentOS?rtl]#?yum?grouplist|less

安裝開發工具

[root@CentOS?rtl]#?yum?groupinstall?"Development?tools"?-y

[root@CentOS?rtl]#?make?

生成了8712u.ko

[root@CentOS?rtl]#?ll?/lib/modules/2.6.32-431.el6.i686/kernel/drivers/net/wireless/8712u.ko

加載模塊

[root@CentOS?rtl]#?modprobe?8712u?

查看是否加載上剛才的模塊

[root@CentOS?rtl]#?lsmod?|grep?8712u?

8712u?????????????????329674??0?

查看無線網卡有命令iwconfig

[root@CentOS?rtl]#?iwconfig

-bash:?iwconfig:?command?not?found

提示沒有這個指令

需要安裝無線網卡工具

[root@CentOS?rtl]#?cd?/media/cdrom/Packages/

[root@CentOS?Packages]#?ll?|grep?-i?wireless

已經可以找到無線網了。想要連接無線網還需要安裝一個wpa工具

進入光盤查看與wpa相關的軟件包

[root@localhost?rtl8191]#?cd?/media/cdrom/Packages/

[root@localhost?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

安裝這個軟件包來連接

[root@localhost?Packages]#?yum?install?wpa_supplicant?-y

安裝好后用?wpa_passphrase來設置無線網的名稱和密碼

格式是?wpa_passphrase?<SSID>?[password]

[root@localhost?Packages]#?wpa_passphrase?NET-1

#?reading?passphrase?from?stdin

123!@#qaz

network={

ssid="NET-1"

#psk="123!@#qaz"

psk=aee0ca338ea19d7e84cc9da72c00836d0ea646594f1e9ff7f01a0173ce853de6

}

設置好后就可以連接了

連接用?wpa_supplicant?命令

[root@localhost?Packages]#?wpa_supplicant?-B?-i?wlan0?-D?wext?-c?/etc/wpa_supplicant/wpa_supplicant.conf?

???????-B?后臺運行?-i?選擇網卡?-D?wext?-c?配置文件地址

動態獲得IP地址

[root@localhost?Packages]#?dhcpclient?wlan0

編輯開機腳本

[root@localhost?Packages]#?vim?/etc/rc.d/rc.local

添加3條命令

modprobe?8712u

wpa_supplicant?-B?-i?wlan0?-D?wext?-c?/etc/wpa_supplicant/wpa_supplicant.conf

dhcpclient?wlan0
