把安装有win 7的笔记本变成无线路由器

Set Windows 7 as WiFi HotSpot

如果无线网卡支持virtual wi-fi，以管理员身份在命令行下执行

netsh wlan set hostednetwork mode=allow ssid=jia key=MyPassword keyUsage=persistent

netsh wlan start hostednetwork

暂停wlan， net wlan stop hostednetwork
取消虚拟网卡， netsh wlan set hostednetwork mode=disallow

或者创建一个快捷方式：
Target [C:\Windows\System32\cmd.exe /c "netsh wlan set hostednetwork mode=allow ssid=jia key=MyPassword  keyUsage=persistent && netsh wlan start hostednetwork && pause"]

From Properties=>Shortcut page:
Tick [Advanced=>Run as Administrator]
Icon from "%SystemRoot%\System32\WlanMM.dll"
