Problems with Your Internet Connection

Your MacBook Pro has the Network Setup Assistant application to help walk you
through setting up an Internet connection. Open System Preferences and click
Network. Click the “Assist me” button to open Network Setup Assistant.

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.

Choose Apple () > System Preferences.

Click Network and then click “Assist me.”

Click Diagnostics to open Network Diagnostics.

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 try
the following steps.

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. Also check the cables and power supplies to Ethernet hubs and routers.
