82 Appendix C Connecting to the Internet

PPPoE Connections

If you are unable to connect to your Internet service provider using PPPoE, first check

the cables and power supplies, then turn the power off and on and reset the modem

hardware.

Check System Preferences settings:

1 Choose Apple () > System Preferences.

2 Click Network.

3 Choose Network Port Configurations from the Show pop-up menu.

4 Drag Built-in Ethernet to the top of the Port Configurations list.

5 Choose Built-in Ethernet from the Show pop-up menu.

6 Click PPPoE.

7 Select “Connect using PPPoE.”

8 Check the Account Name field to be sure you have entered the correct information

from your ISP.

9 Retype your password if you chose to save your password, to be sure it is correct.

10 Click TCP/IP. Make sure you’ve entered the correct information from your ISP

in this pane.

11 Click Apply Now.

Network Connections

If you have two or more computers attempting to share an Internet connection, be

sure that your network is set up properly. You need to know if your ISP provides only

one IP address or if it provides multiple IP addresses, one for each computer.

If only one IP address is used, then you must have a router capable of sharing the

connection, also known as network address translation (NAT) or “IP masquerading.” For

setup information, check the documentation provided with your router or ask the

person who set up your network. The AirPort Extreme Base Station may be used to

share one IP address among multiple computers. For information on using the AirPort

Extreme Base Station, check the onscreen help or visit the Apple AirPort website at

www.apple.com/airport.

If you cannot resolve the issue using these steps, contact your ISP.
