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:

Wireless, Broadband (PPPoE), and Dial-up. Click Broadband (PPPoE).

name and password provided by your ISP in the text boxes provided. As neces-

sary, select the “Show characters” checkbox to see your password and verify the

correct syntax.

6. Select the “Remember this password” checkbox to save your password for future

use.

7. Windows Vista also enables you to share your connection with anyone with

access to your computer. If you want other users to have access to this connec-

tion, check “Allow other people to use this connection.”

8. Click Connect to create the connection and establish a connection to the ISP.
