Network Connections

Make sure the Ethernet cable is plugged into your MacBook Pro and into the network. Check the cables and power supplies to your Ethernet hubs and routers.

If you have two or more computers attempting to share an Internet connection, be sure that your network is set up properly. You need to know whether your ISP provides only one IP address or multiple IP addresses, one for each computer.

If only one IP address is provided, then you must have a router capable of sharing

the connection, also known as network address translation (NAT) or “IP masquerading.” For setup information, check the documentation provided with your router or ask the person who set up your network. The AirPort base station can be used to

share one IP address among multiple computers. For information about using an AirPort base station, check Mac Help or go to the AirPort Extreme website at www.apple.com/support/airport.

If you can’t resolve the issue using these steps, contact your ISP or network administrator.
