Chapter 17: Mastering Dial-Up, Broadband, and On-the-Go Networking
The Sharing tab allows you to configure the Internet Connection Sharing feature of
Windows Vista, as seen in Figure 17-13. To enable this feature, check the associated
box. This will allow other users to connect to the connection you define from the
drop-down menu. You have the option to associate any network connection defined
to your system with this feature.
Creating Broadband Connections
Most people have a broadband connection to the Internet these days. Broadband
connections are defined by their bandwidth and fall into five categories: cable,
ADSL, SDSL, fiber to the premises, and broadband wireless. Any of these types of
connections provides high-speed access to the Internet. Each connection requires
service from an ISP. If the ISP allows you to connect without having to provide a
username and password, such as with cable modem service, you typically don’t need
to establish a separate broadband connection. Instead, you simply need to connect
your computer to the cable modem provided by the cable provider. On the other
hand, if your broadband provider requires you to use a username and password it
has assigned, you’ll need to create a broadband connection that sets the username
and password for you.
In the Network and Sharing Center, you can set up a broadband connection by fol-
lowing these steps:

access to your computer. If you want other users to have access to this connec-
tion, check “Allow other people to use this connection.”
