Appendix C Connecting to the Internet 119
Troubleshooting Your Connection
If you have trouble with your Internet connection, you can try the steps in this section
for your type of connection or you can use Network Diagnostics.
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 Modem, and LAN Internet Connections
If you can’t connect to the Internet using your cable modem, DSL modem, or local area
network (LAN), see the following instructions.
Important: Instructions that refer to modems do not apply to LAN users. LAN users
might have hubs, switches, routers, or connection pods that cable modem 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.
