Windows 7 provides a function called HostedNetwork, documented at MSDN, which allows your computer to simultaneously connect to a wireless network and broadcast your own secondary network. To use this feature, you must have a compatible wireless card.

To configure the network, in an elevated command prompt type:

netsh wlan set hostednetwork SSID=<ssid> key=<key> keyUsage=persistent

after which you can start it with netsh wlan start hostednetwork and stop it with netsh wlan stop hostednetwork. Currently there is no way of running an unsecured hosted network.

Once you set up the hostednetwork, you can use it to share your existing wireless network.

However, if you intend to share a wired internet connection, you do not need to set up hostednetwork. To share a wired network, right click on the "Local Area Connection" entry in "Network Connections" (Control Panel), and select the "Advanced" tab, and check "Allow other ...". A detailed guide on how to set up Internet Connection Sharing under Windows XP can be found at the Microsoft Knowledge Base

Missing some information here that would probably help someone to provide a solution - what operating system is installed on the laptop?
