Controlling the range of your network

You can limit the range of your AirPort network to control who has access to it by reducing the transmission power setting. When you shorten the range of the network, only computers close enough to the base station or Time Capsule can join the network.

To set the transmission power:

  1. Open AirPort Utility, located in the Utilities folder in the Applications folder on a computer using Mac OS X, and in Start > All Programs > AirPort on a Windows computer.

  2. Select the device you want to control, and then click Manual Setup. Enter the password if necessary.

  3. Click AirPort in the toolbar, and then click Wireless.

  4. Click Wireless Network Options and then choose a setting from the Transmit Power pop-up menu (the lower the percentage, the shorter the network range).
