Troubleshooting Your Connection

Cable Modem, DSL, and LAN Internet Connections

If you can’t connect to the Internet using your cable modem, DSL, or local area network (LAN), see the following steps.

Important: Instructions that refer to modems do not apply to LAN users. LAN users may have hubs, switches, routers, or connection pods that cable and DSL modem users do not. LAN users should contact their network administrator rather than an ISP.

Check the cables and power supplies

Make sure all modem cables are firmly plugged in, including the modem power cord, the cable from the modem to the computer, and the cable from the modem to the wall jack. Check the cables and power supplies to Ethernet hubs and routers.

Turn the modem off and on and reset the modem hardware

Cycle the power on your DSL or cable modem by turning it off for a few minutes and then turning it back on. Some ISPs recommend that you unplug the modem’s power cord. If your modem has a reset button, you can press it either before or after cycling the power.

PPPoE Connections

If you are unable to connect to your ISP using PPPoE, first check the cables and power supplies, then turn the modem off and on again and reset the modem hardware.

Check System Preferences settings

1Choose Apple (K) > System Preferences from the menu bar.

2Click Network.

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

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

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

6Click PPPoE.

7Select “Connect using PPPoE.”

8Check the Account Name field to be sure you have entered the correct information from your ISP.

9If you chose to save your password, retype it to make sure it is correct.

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

11Click Apply Now.
