Go into network set up
a shared Internet connection using ICS (Internet Connection Sharing)
You can use Internet
Connection Sharing (ICS) to share an Internet connection among two or more
computers on a network. First, you need one computer, called the host
computer, that is connected to the Internet and that
has a separate connection to the other computers on your network. You enable ICS
on the Internet connection. The other computers on your network then connect to
the host computer, and from there to the Internet through the host computer's
shared Internet connection.
If your computer is connected to a network, network policy
settings might prevent you from completing these steps.
On the host computer (the computer whose Internet connection you
plan to share):
to open Network Connections.
Right-click the connection that you want to share, and then click
you are prompted for an administrator password or confirmation, type the
password or provide confirmation.
Click the Sharing tab, and then select the
Allow other network users to connect through this computer’s
Internet connection check box.
