於CentOS6.5 安裝RT73無線網卡

安裝Linux測試機又不想牽線，只好來實驗一下安裝無線網卡，將不使用Network manager

 

範例:

OS: CentOS 6.5 minimal

Wireless card: RT73 chip

AP SSID: shazi

準備套件: iw , wpa_supplicant , linux-firmware , dhcp3-client



套件安裝

安裝RT73 driver

1. 安裝firmware的repo , elrepo

shell# rpm -Uvh http://www.elrepo.org/elrepo-release-6-6.el6.elrepo.noarch.rpm

 

2. install RT73 firmware

shell# yum --enablerepo=elrepo install rt73usb-firmware

檢查是否載入RT73:

shell# lsmod | grep rt73

找到rt37 use message



 

shell# iwconfig

找到無線網卡wlan0



 

3. yum install wi  (Wireless tools)

 

 

設定

SETP.1 編輯ifcfg-wlan0

shell# vim/etc/sysconfig/network-scripts/ifcfg-wlan0

TYPE=Wireless

WPA=yes

ONBOOT=yes

 

 

因為我的AP有WPA2的加密認證，所以要使用wpa_supplicant來處理WPA

 

SETP.2 產生wpa_supplicant.conf 所需要的psk金鑰加密

shell# wpa_passphrase shazi password

ex:

network={
ssid="shazi"
#psk="password"
psk=7e5ca53c4a8ad04b8a3962d0e0b84ad584660c5fc2542bcef1d178fac85
}

 

SETP.3 將wpa_passphrase產生的金鑰加入wpa_supplicant.conf

shell# vim /etc/wpa_supplicant/wpa_supplicant.conf

ex:

ctrl_interface=/var/run/wpa_supplicant
ctrl_interface_group=wheel

network={
ssid="shazi"
#psk="password"
psk=7e5ca53c4a8ad04b8a3962d0e0b84ad584660c5fc2542bcef1d178fac85
}

 

SETP.4 綁定wpa_supplicant使用的網卡

shell# vim /etc/sysconfig/wpa_supplicant

ex:

INTERFACES="-iwlan0"

DRIVERS="-Dwext"

 

 

Connect Test Case:

1. wpa_supplicant -Dwext -iwlan0 -c /etc/wpa_supplicant/wpa_supplicant.conf

messag:  Connection to mac is completed , but need stop use Ctrl+C

 

2. iw dev wlan0 connect shazi

 

3. ifconfig wlan0 up



4. check reboot is OK.

 

if you not get the IP , maybe not open dhclient.

ex:

shell# dhclient

or

shell# vim /etc/sysconfig/network-scripts/ifcfg-wlan0

BOOTPROTO=dhcp
