Sharing Your Internet Connection
Your Mac is a perfect Internet-sharing platform because it includes both Ethernet and wireless network connections. You can, in a matter of minutes, create a wireless network using just your computer and a cable or DSL modem.
Sharing Your Connection
To share your connection with other Macs, PCs, or devices, you’ll need a minimum of two network interfaces on your system—such as Ethernet and WiFi. Assuming you meet that qualification, you can share one network interface to the other by following these steps:
In the System Preferences window, click the Sharing icon.
- Click the Internet Sharing service label. (Note: The checkbox is initially disabled!)
- Use the Share Your Connection From drop-down menu to choose how you are connected to the Internet (Ethernet, Airport, iPhone, and so on).
- Within the To Computers Using list, click the checkboxes in front of each of the interfaces where the connection should be shared.
If you’re sharing a connection over your Wi-Fi card, a Wi-Fi Options button appears. Click this button to configure how your computer presents itself wirelessly.
- Set the name of the wireless network you are creating.
- Leave the channel set to the default.
- If you want to enable password protection for the network, choose WPA2 Personal from the Security drop-down, and then provide a password.
Click OK to save your settings.
- Click the checkbox in front of the Internet Sharing service.
Close the System Preferences.
- Connect to the new wireless network from other computers as described in Chapter 3. You should set the other computers to configure themselves automatically rather than manually configuring the network (not shown).
