Before you begin, be sure of the following:
1. You have an active ISP account and can access the Internet.
Open a web browser (e.g, Internet Explorer, Mozilla Firefox, etc.) and visit an Internet
web site. If you successfully see the web site, you are connected. If not, you need to
establish an active Internet connection before proceeding with the installation.
2. Preconfigure your computer to automatically obtain an IP address.
If not already done, set up the LAN interface on your computer to obtain an IP address
automatically. If you are already set up for automatic IP, you should encounter no
problems with your set up.
To obtain an automatic IP address
1. Go to the Start menu
2. Open the Control Panel and then Network Connections.
3. Right click on the Local Area Connection icon
a. Choose Properties
b. Double-click on Internet Protocol (TCP/IP) from the list.
c. Check the “Obtain IP address automatically” radial button.
d. Click OK to confirm the change.
