Troubleshooting Your Connection

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

To use Network Diagnostics:

1Choose Apple ( ) > System Preferences.

2Click Network and then click ÒAssist me.Ó

3Click Diagnostics to open Network Diagnostics.

4Follow the onscreen instructions.

If Network Diagnostics canÕt 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 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 on and off and reset the modem hardware

Turn off your DSL or cable modem for a few minutes, then turn it back on. Some ISPs recommend that you unplug the modemÕs power cord. If your modem has a reset button, you can press it either before or after you turn the power off and on.
