Troubleshooting Your Connection, 119 | Apple APLLE MACBOOK guide

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:

1Choose Apple () > System Preferences.

2Click Network and then click “Assist me.”

3Click Diagnostics to open Network Diagnostics.

4Follow 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 may 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.
