<wbr></wbr>

1、 支持wifi

<wbr style="font-family: simsun; font-size: 14px; line-height: 21px;"><span style="font-family: simsun; font-size: 14px; line-height: 21px;"></span><wbr style="font-family: simsun; font-size: 14px; line-height: 21px;"><span style="font-family: simsun; font-size: 14px; line-height: 21px;"></span><wbr style="font-family: simsun; font-size: 14px; line-height: 21px;"><span style="font-family: simsun; font-size: 14px; line-height: 21px;"></span><wbr style="font-family: simsun; font-size: 14px; line-height: 21px;"><span style="font-family: simsun; font-size: 14px; line-height: 21px;"></span>一般来说，现在的手提电脑都会内置wifi功能，而且大部分的也支持虚拟无线路由，查看自己的无线无卡是否支持虚拟无线路由如下：</wbr></wbr></wbr></wbr>

<wbr style="font-family: simsun; font-size: 14px; line-height: 21px;"><span style="font-family: simsun; font-size: 14px; line-height: 21px;"></span><wbr style="font-family: simsun; font-size: 14px; line-height: 21px;"><span style="font-family: simsun; font-size: 14px; line-height: 21px;"></span><wbr style="font-family: simsun; font-size: 14px; line-height: 21px;"><span style="font-family: simsun; font-size: 14px; line-height: 21px;"></span><wbr style="font-family: simsun; font-size: 14px; line-height: 21px;"><span style="font-family: simsun; font-size: 14px; line-height: 21px;"></span>1）用CMD命令，在DOS界面下输入：<wbr><span style="color:#cc0000;">netsh wlan show drivers</span></wbr></wbr></wbr></wbr></wbr>

<wbr style="font-family: simsun; font-size: 14px; line-height: 21px;"><span style="font-family: simsun; font-size: 14px; line-height: 21px;"></span><wbr style="font-family: simsun; font-size: 14px; line-height: 21px;"><span style="font-family: simsun; font-size: 14px; line-height: 21px;"></span><wbr style="font-family: simsun; font-size: 14px; line-height: 21px;"><span style="font-family: simsun; font-size: 14px; line-height: 21px;"></span><wbr style="font-family: simsun; font-size: 14px; line-height: 21px;"><span style="font-family: simsun; font-size: 14px; line-height: 21px;"></span>2）找到支持的承载网络，就说明是可以用虚拟WIFI功能（如下图红色横线）</wbr></wbr></wbr></wbr>

<wbr style="font-family: simsun; font-size: 14px; line-height: 21px;"><span style="font-family: simsun; font-size: 14px; line-height: 21px;"></span><wbr style="font-family: simsun; font-size: 14px; line-height: 21px;"><span style="font-family: simsun; font-size: 14px; line-height: 21px;"></span><wbr style="font-family: simsun; font-size: 14px; line-height: 21px;"><span style="font-family: simsun; font-size: 14px; line-height: 21px;"></span><wbr style="font-family: simsun; font-size: 14px; line-height: 21px;"><span style="font-family: simsun; font-size: 14px; line-height: 21px;"></span><img src="http://img.my.csdn.net/uploads/201301/20/1358675999_5314.png" alt=""><wbr></wbr></wbr></wbr></wbr></wbr>

2、 配置wifi

<wbr><wbr><wbr><wbr>通过上面步骤确定你的网卡支持无线路由后，现在尝试开启无线路由，将下面的语句做成bat</wbr></wbr></wbr></wbr>批处理文件：

netsh wlan set hostednetwork mode=allow   
netsh wlan set hostednetwork ssid=homerwifi key=12345678
netsh wlan start hostednetwork
pause

注： ssid 是无线路由名字， key 是密码， 例如：ssid=homerwifi key=12345678

<wbr></wbr>

3、 生成wifi

<wbr style="font-family: simsun; font-size: 14px; line-height: 21px;"><span style="font-family: simsun; font-size: 14px; line-height: 21px;"></span><wbr style="font-family: simsun; font-size: 14px; line-height: 21px;"><span style="font-family: simsun; font-size: 14px; line-height: 21px;"></span><wbr style="font-family: simsun; font-size: 14px; line-height: 21px;"><span style="font-family: simsun; font-size: 14px; line-height: 21px;"></span><wbr style="font-family: simsun; font-size: 14px; line-height: 21px;"><span style="font-family: simsun; font-size: 14px; line-height: 21px;">用管理员身份运行步骤2的bat批处理脚本，DOS输出信息如下：</span><br></wbr></wbr></wbr></wbr>

<wbr style="font-family: simsun; font-size: 14px; line-height: 21px;"><span style="font-family: simsun; font-size: 14px; line-height: 21px;"></span><wbr style="font-family: simsun; font-size: 14px; line-height: 21px;"><span style="font-family: simsun; font-size: 14px; line-height: 21px;"></span><wbr style="font-family: simsun; font-size: 14px; line-height: 21px;"><span style="font-family: simsun; font-size: 14px; line-height: 21px;"></span><span style="font-family: simsun; font-size: 14px; line-height: 21px;"><img src="http://img.my.csdn.net/uploads/201301/20/1358677486_2991.png" alt=""></span><br></wbr></wbr></wbr>

注： 每一命令行如上面红线标出，其中"netsh wlan show drivers"　执行结果为"The hosted network started." 则继续

4、 共享wifi

<wbr style="font-family: simsun; font-size: 14px; line-height: 21px;"><span style="font-family: simsun; font-size: 14px; line-height: 21px;"></span><wbr style="font-family: simsun; font-size: 14px; line-height: 21px;"><span style="font-family: simsun; font-size: 14px; line-height: 21px;"></span><wbr style="font-family: simsun; font-size: 14px; line-height: 21px;"><span style="font-family: simsun; font-size: 14px; line-height: 21px;"></span><wbr style="font-family: simsun; font-size: 14px; line-height: 21px;"><span style="font-family: simsun; font-size: 14px; line-height: 21px;">步骤3成功后，wifi host就已经创建成功，下面工作就是需要共享wifi，具体步骤如下：</span><br></wbr></wbr></wbr></wbr>

<wbr style="font-family: simsun; font-size: 14px; line-height: 21px;"><span style="font-family: simsun; font-size: 14px; line-height: 21px;"></span><wbr style="font-family: simsun; font-size: 14px; line-height: 21px;"><span style="font-family: simsun; font-size: 14px; line-height: 21px;"></span><wbr style="font-family: simsun; font-size: 14px; line-height: 21px;"><span style="font-family: simsun; font-size: 14px; line-height: 21px;"></span><wbr style="font-family: simsun; font-size: 14px; line-height: 21px;"><span style="font-family: simsun; font-size: 14px; line-height: 21px;"></span>1） 打开“控制面板”——》 “网络与连接”——》“查看网络状态和任务”——》“修改适配器配置”；</wbr></wbr></wbr></wbr>

或直接点击桌面右下角“打开网络和共享中心”——》“修改适配器配置”

<wbr style="font-family: simsun; font-size: 14px; line-height: 21px;"><span style="font-family: simsun; font-size: 14px; line-height: 21px;"></span><wbr style="font-family: simsun; font-size: 14px; line-height: 21px;"><span style="font-family: simsun; font-size: 14px; line-height: 21px;"></span><wbr style="font-family: simsun; font-size: 14px; line-height: 21px;"><span style="font-family: simsun; font-size: 14px; line-height: 21px;"></span><wbr style="font-family: simsun; font-size: 14px; line-height: 21px;"><span style="font-family: simsun; font-size: 14px; line-height: 21px;"></span>2） 会看到如下图：</wbr></wbr></wbr></wbr>

问题与分析

按网上的很多方法在自己实践的过程中，遇到了一些问题，现在分享出来让大家少走弯路

1、 步骤1和2，执行netsh wlan show drivers 时总得不出正确结果，分析原因如下：

（1） 禁用了无线网络，因为netsh是windows网络配置命令，netsh wlan 是开启无线网络的意思，你禁用了无线网络当然就不对

（2） 无线驱动失效，有时笔记本可以上网但无法搭建wifi host，有可能是无线驱动过时或不完整，尝试升级或卸载后重装驱动

2、 连接”无线网络连接 2“（homerwifi）后仍然无法上网，分析原因如下：

没有分享主网络给新建的无线路由，请重新检查步骤4并执行其第3）小步骤

3、 主网络只有3G网卡才支持搭建新的无线路由吗

不是，本文是以3G网卡做示例，其实本人还测试过wifi、网线做主网络搭建无线路由并都成功，3G网卡更适合出差、旅行等无wifi环境中使用
