Connecting to a Wired Network

The most common type of network connection in the business world is a wired Ethernet connection. The cables used to connect to the network look like oversized phone connectors and, as luck has it, plug directly into your MacBook’s Ethernet port. (MacBook Air owners will need to buy Apple’s USB Ethernet adapter.) The MacBook supports gigabit Ethernet, making it capable of exchanging information at extremely high speeds.

Making an Ethernet (Wired) Connection

On a network that is set up to automatically configure your computer using DHCP, the most complicated thing you need to do is plug in the network cable!

  1. Open the System Preferences panel and click the Network icon.
  2. The network preference panel displays. All of the activate network interfaces are listed here. Red dots indicate that no connection is present on the interface.
  3. Plug the network cable into the left side of your MacBook.
  4. After a few seconds, the interface should update, showing a green dot for an active connection. The pane to the right of the interfaces displays the information that your computer is using to communicate online.
