我安装了 Ubuntu 12.04 和 Windows 8，并且具有双启动选项。
无线已被硬件开关禁用。
如何开启WiFi？
我尝试了以下命令：

答案1
首先安装所有必要的编译工具，并从其 git 存储库下载最新的驱动程序：（以 TL-WN725N 为例）
$$ sudo apt-get install build-essential linux-headers-generic git
$$ mkdir ~/RTL8188EU
$$ cd ~/RTL8188EU
$$ git clone git://github.com/lwfinger/rtl8188eu.git
之后，可以编译并安装驱动程序：
进入文件夹并执行以下命令。
$$ make
$$ sudo make install
新的内核模块可以通过modprobe加载，并可以全系统安装以实现自动加载：
$$ sudo depmod -a
$$ sudo update-initramfs -u
$$ sudo modprobe 8188eu
（自动启动：）要在每次启动时启用模块，请将模块添加到 /etc/modules
$$ echo 8188eu >> /etc/modules
运行命令
$$ lspci -v
并搜索您的内置 wifi 卡...
03：00.0 网络控制器：英特尔公司 WiFi Link 5100 子系统：英特尔公司 WiFi Link 5100 AGN 标志：总线主控、快速设备、延迟 0、IRQ 47 内存位于 d6500000（64 位，不可预取）[size=8K] 功能：[c8] 电源管理版本 3 功能：[d0] MSI：启用+计数=1/1 可屏蔽-64 位+ 功能：[e0] 快速端点，MSI 00 功能：[100] 高级错误报告功能：[140] 设备序列号 00-24-d6-ff-ff-3e-5e-a4 正在使用的内核驱动程序：iwlwifi
现在阻止那张卡....
$$ sudo echo "blacklist iwlwifi" >> /etc/modprobe.d/blacklist.conf
现在运行
$$ lsmod | grep sony
用您的笔记本电脑的公司名称替换 sony....
阻止您的笔记本电脑（例如，对于索尼 vaio，它是“sony_laptop”...
$$ sudo echo "blacklist sony_laptop" >> /etc/modprobe.d/blacklist.conf
完毕..！！！
现在重新启动...即使您的无线开关已关闭，您也将能够运行您的 wifi 适配器....！！
