一步一步解决centos6.5配置无线网卡的问题

1、配置本地yum源

[local]
name=local
baseurl=file:///mnt/cdrom
enable=1
gpgcheck=0

2、安装libnl

rpm -ivh /mnt/cdrom/Packages/libnl-1.1.4-2.el6.x86_64.rpm

3、安装wpa_supplicant

rpm -ivh /mnt/cdrom/Packages/wpa_supplicant-0.7.3-4.el6_3.x86_64.rpm

4、修改wpa_supplicant配置文件

vim /etc/sysconfig/wpa_supplicant

INTERFACES="-iwlan0"

# Use the flag "-D" before each driver, like so:
# DRIVERS="-Dwext"
DRIVERS="-iDwext"

6、确定网卡类型

03:00.0 Network controller [0280]: Realtek Semiconductor Co., Ltd. RTL8188CE 802.11b/g/n WiFi Adapter [10ec:8176] (rev 01)

7、确认是否有无线网卡驱动，如果输出如下，则证明没有无线网卡驱动

[root@test data]# iwconfig
lo no wireless extensions.

eth0 no wireless extensions.

8、安装网卡驱动确定系统内核版本

[root@test rtl8192ce_linux_2.6.0005.1116.2010]# uname -r
2.6.32-431.el6.x86_64

9、下载对应的网卡驱动，编译安装

root@test rtl8192ce_linux_2.6.0005.1116.2010]# make
make: *** /lib/modules/2.6.32-431.el6.x86_64/build: No such file or directory. Stop.
make: *** [all] Error 2

10、如何输出上面的步骤，则需要安装kernel-devel

yum install kernel-devel -y

11、先做清理

make clean

12、安装gcc

[root@test rtl8192ce_linux_2.6.0005.1116.2010]# make
expr: syntax error
make[1]: Entering directory `/usr/src/kernels/2.6.32-431.el6.x86_64'
/usr/src/kernels/2.6.32-431.el6.x86_64/arch/x86/Makefile:81: stack protector enabled but no compiler support
make[1]: gcc: Command not found

13、再次编译make，输出如下，则编译通过

CC [M] /data/rtl8192ce_linux_2.6.0005.1116.2010/HAL/rtl8192/../../rtllib/rtllib_crypt_wep.o

make[1]: Leaving directory `/usr/src/kernels/2.6.32-431.el6.x86_64'

14、编译安装

[root@test rtl8192ce_linux_2.6.0005.1116.2010]# make install
make[1]: Entering directory `/usr/src/kernels/2.6.32-431.el6.x86_64'

depmod -a
make[1]: Leaving directory `/data/rtl8192ce_linux_2.6.0005.1116.2010/HAL/rtl8192'

15、重启检查无线网卡已经ok

[root@test ~]# iwconfig
lo no wireless extensions.
