You can configure your Windows 7 laptop as a WIFI access point.
right-click the Cmd.exe link and select Run as Administrator.
Now enter the following command:
netsh wlan set hostednetwork mode=allow ssid=MyNet key=MyPassword
and press [Enter]. Replace “MyNet” with the name you want to use for your network, and “MyPassword” with a password that is a little more difficult to guess.
Still at the command prompt, type
netsh wlan start hostednetwork
and press [Enter] to start the virtual adapter.
Now click on "Control Panel"> "Network and Internet"> "Network and Sharing Center"> "Change adapter settings", right-click your Internet connection and select "Properties". Go to the "Sharing" tab, check the box "Allow other network users to connect ...", select your virtual Wi-Fi adapter - and this.
