How to turn your Windows 7 laptop into a wireless hotspot

1.    Open command prompt as an administrator

2.    Now type the following command:

netsh wlan set hostednetwork mode=allow ssid=MyNetwork key=MyPassword

Press enter

Replace "MyNetwork" with the name you'd like to use for your custom network, and "MyPassword" with a password.

3.    Now type the following command 

netsh wlan start hostednetwork

and press [Enter] to fire up the virtual adapter.

4.    Now click Control Panel >> Network and Internet >> Network and Sharing Centre >> Change Adapter Settings, 

5.    Right-click your internet connection and select Properties. 

6.    Click the Sharing tab, check "Allow other network users to connect...", choose your virtual Wi-Fi adaptor - and it’s done.

7.    Any nearby Wi-Fi enabled device will see a new network appear with the SSID defined above. They'll be able to connect to it with password provided, and can then immediately share internet connection.

While it's worth knowing how to do this manually, if it's something you do often then you'll probably prefer a simpler solution.
