I established a home network using the Network Setup Wizard (NSW). I have a LinkSys wireless G-router connected to my desktop, running Win XP SP3, with an ethernet cable. My Win 7 laptop connects to the router wirelessly. I can ping each computer from the other and SyncToy can synchronize files between the two, so I know (or at least think I know) that the network is functional. However, the NSW did not enable Internet Connection Sharing (ICS), and I can't web browse or e-mail from my laptop using my desktop's dial-up modem connection.

When I try to manually enable ICS, it changes the IP address of my desktop and its connection to the rest of the network is severed. How can I enable ICS without losing my network?

Thank you,
