Traditional computer networks use routers and wired connections to link the computers in a group. A Virtual Private Network (VPN) uses the Internet to connect the same group of computers. If you use a VPN in conjunction with your Wi-Fi wireless internet router, it can give you the same benefits of a wired network connection without the restrictions of being tethered to a central router. With a VPN connection, your network is as flexible and portable as your wireless Internet connection.
Open the Control Panel, then choose the "Network and Sharing Center."
Click "Setup a new connection or network."
Click, "Use my Internet connection (VPN)"
Enter your IP address into the "Internet Address" bar. You can also use your company's website address if it can support a VPN connection.
Choose a "Destination Name" so that you can easily recognize your network when you want to use it in the future. Click "Next"
Set login info and passwords then click "Create" to establish your network. You can leave all these fields blank if you feel comfortable with a network that does not require a password.
