I'm not sure I understand what you're trying to do, but it sounds as though you want to connect your laptop "wirelessly" (presumably to a wireless router) and then use the laptop to "host" a wired network via a network "switch".

If this is correct, you would enable "Internet Connection Sharing" on the laptop's Wireless Network Connection, connect the laptop's Local Area Connection to the switch and the other computers connected to the switch should have network and internet access, provided the laptop is running. As "Internet Connection Sharing" operates in the 192.168.0.0 subnet, the wireless router that the laptop connects to must operate in a different subnet to avoid IP addressing conflicts.

To enable “Internet Connection Sharing” (in Windows XP), open the Network Connections folder, right click your Wireless Network Connection, select Properties and then the Advanced tab. Tick the box “Allow other network users to connect through this computer’s Internet connection”.

When you enable "Internet Connection Sharing" on the Wireless Network Connection, it will automatically configure your Local Area Connection with the IP address 192.168.0.1 and subnet mask 255.255.255.0. The "Client" PCs' Local Area Connections should be set to get their IP addresses automatically, which they do by DHCP from the "Host" PC. Also, if you run the Zone Alarm firewall in your "Host" PC, the Internet Zone Security level must be reduced from High to Medium or "ICS" traffic will be blocked. In any case, whatever firewall software you use needs to be configured to allow access to the computers in the local network.

The obvious question is - if you do have a wireless router, why are you not connecting all of the computers directly to that? Windows "Internet Connection Sharing" is not the most reliable method at the best of times.
