84 Appendix C Connecting to the Internet

Troubleshooting Your Connection

If you have trouble with your Internet connection, you can try the steps in this section.

Network Diagnostics

If you can’t connect to the Internet, use Network Diagnostics to investigate your

network settings.

To use Network Diagnostics:

1 Choose Apple () > System Preferences.

2 Click Network and then click “Assist me.”

3 Click Diagnostics to open Network Diagnostics.

4 Follow the onscreen instructions.

If Network Diagnostics can’t resolve the problem, there may be a problem with the

Internet service provider (ISP) you are trying to connect to, with an external device you

are using to connect to your ISP, or with the server you are trying to access. You can

also try the following steps.

Cable Modem, DSL, and LAN Internet Connections

Make sure all modem cables are firmly plugged in, including the modem power cord,

the cable from the modem to your computer, and the cable from the modem to the

telephone jack. Check the cables and power supplies to Ethernet hubs and routers.

Turn the modem on and off and reset the modem hardware

Turn off your DSL or cable modem for a few minutes, and then turn 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 you turn the power off and on.
