Win7系统下默认是支持虚拟无线路由器功能的，设置方法如下：
win7无线AP命令
1.启用并设定虚拟WiFi网卡：
运行命令： netsh wlan set hostednetwork mode=allow ssid=tsky key=tsky.cc
注意：
下面参数可以自由变换
mode：是否启用虚拟WiFi网卡，改为disallow则为禁用。
ssid：无线网名称，最好用英文(以tsky为例)。
key：无线网密码，八个以上字符(以tsky.cc为例)。
以上三个参数可以单独使用，例如只使用mode=disallow可以直接禁用虚拟Wifi网卡。
在“网络连接”窗口中，右键单击已连接到Internet的网络连接，选择“属性”→“共享”，勾上“允许其他••••••连接(N)”
继续在命令提示符中运行：netsh wlan start hostednetwork
还可以通过专门的软件来实现，如Connectify
下面是方法：
1.首先你的宽带连接要设置可以共享。
2.下Connectify到电脑，双击。
3.在任务栏中找到Connectify，右键单击，选择Wizard，按步骤一步一步设置。（看不懂英文的可以google一下）
4.设置完成后，在小7上开启WLAN搜索，找到你设置的热点即可以上网。（连接成功后会在Connected Clients -0会变成Connected Clients -1，这里的1意思是已经有一个客户端通过Connect连接上网络了。
5.经测试，用UC，UC播放器看视频，上QQ等都十分流畅！太爽了！
补充：
安装使用Connectify需要什么条件 ？
A 一台安装了windows7操作系统的笔记本电脑。
B 此笔记本电脑的无线网卡在下面的兼容列表中。
