Internet sharing under Windows 7 (共享 Internet 无线网络)

Found the below link and internet sharing (a.k.a. tethering) is a standard feature in Windows. Once you know the trick, it's easy. It allows me to create an Wifi Access Point on my desktop computer to share to my tablets in the office where I have no access to any Wifi network.

And below summary on what to do,

  1. decide the SSID and password you want to use
  2. start console with administrative right (i.e. from the windows search prompt, press ctrl-shift-enter after typing 'cmd')
  3. enter 'netsh wlan set hostednetwork mode=allow ssid=yourssid key=yourpassword' to set the Access Point
  4. edit the network interface (select the one where Internet is available if you have multiple interfaces),
    • from the Sharing tab, enable sharing to the virtual interface associated with your wifi adapter
    • uncheck to other others to manage your setting on the same Sharing tab
  5. from the console again, enter 'netsh wlan start hostednetwork'

To disable the network, use the following command,

'netsh wlan set hostednetwork mode=disallow ssid=itgeekdiary key=typepassword' 

This works for my perfectly. Thank you for the notes in www.itgeekdiary.com

P.S. just found the below which seem to be more user friendly, for those who want to try (and who read Chinese also)
