GETTING STARTED - Mac OX: Ad Hoc Network
If your Mac is not on a network, but you'd still like to connect to an iPad, you can create what's called an "ad hoc" network (aka: a computer-to-computer network). This type of direct network actually provides the optimum wireless performance. Follow the instructions below to create the ad hoc network on your Mac, then connect to the new network with your iPad:
To create a computer-to-computer network, simply choose "Create Network" from the AirPort status icon in the menu bar and Press OK.
• If the icon isn’t in the menu bar, choose Apple > System Preferences, and then click Network. Click AirPort and select the "Show AirPort Status in Menu Bar" checkbox.
• If you wish, you can give the network a different name and select a channel from the pop-up menu. The default channel is 11, but you can also choose channel 1 or 2.
• If you want to protect your network with a password, you can select the "Require Password" checkbox and type in your password.
