Wide Area Network is a telecommunication network that is used to cover a broad area. The WAN miniport is a software adapter used by the operating system to access the WAN. Most of the time, the WAN miniport is used to connect to the Internet through a Point-to-point protocol over Ethernet connection. In essence, to connect through the WAN miniport, you must have a valid PPPoE connection set up. When you initiate the connection on a Windows operating system, you briefly see an "Connecting Through WAN Miniport" message.
Go to the "Start" menu, and click on "Control Panel." You can manage almost anything related to the Windows operating system from the Control Panel.
Click on the "View Network Status and Tasks" link in the "Network and Internet" section. Click on the "Set Up a New Connection or Network" link to start creating a PPPoE connection.
Select the "Connect to the Internet" option, and click on the "Next" button. If you already have a connection, then select the "No, Create a New Connection" option, and click "Next."
Click on "Broadband (PPPoE)," and enter your user name in the "User Name" text box and your password in the "Password" text box. Type a name for your new connection in the "Connection Name" text box; you can use anything you want, but it is recommended to use a suggestive name. You can select the "Remember This Password" option if you don't want to type the password each time you connect through the WAN miniport. You can also select the "Allow Other People to Use This Connection" option if you want to allow other users to connect through the WAN miniport using your user name and password.
Click on the "Connect" button to create and test the PPPoE connection. If the connection fails at the "Connecting Through WAN Miniport" window, reinstall or update your Ethernet card drivers. You can find them on the CD or DVD that came with your computer or on the manufacturer's website.
The WAN miniport driver is automatically installed in Windows 7.
