Make sure that it is not Vista that is the problem
1. Open the Network and Sharing Center
2. Open "Manage Network Connections"
3. Open the "Advanced" menu -> Advanced Settings
4. If necessary change the order of connections so that your router net is the first.
Sorry picture is in german but it looks the same.
If this doesnt help, try to enter the IP address of your router in the shareport tool menu
It also works if there is more than one router
