1. 先通过命令查看本机无线网卡的型号。

    [root@chen Desktop]# lspci

    02:00.0 Ethernet controller: Realtek Semiconductor Co., Ltd. RTL8111/8168B PCI Express Gigabit Ethernet controller (rev 06)
    05:00.0 System peripheral: Ricoh Co Ltd Device e823 (rev 07)
    06:00.0 Network controller: Realtek Semiconductor Co., Ltd. RTL8188CE 802.11b/g/n WiFi Adapter (rev 01)

  2. 到Realtek官网查找驱动型号的Linux驱动。

    通过下载得到如下驱动：

    [root@chen Downloads]# ls

    0001-rtl8192ce_linux_2.6.0006.0321.2011.tar.gz

  3. 通过解压文件：tar -zxvf  0001-rtl8192ce_linux_2.6.0006.0321.2011.tar.gz

  4. 进入解压文件，进行安装

    [root@chen Downloads]# cd rtl8192ce_linux_2.6.0006.0321.2011
