If you’re using AirPort Utility on a Macintosh computer, you can use the search field in AirPort Utility to quickly find the setting you’re looking for, such as the IP address or the radio mode of your base station or Time Capsule.
Open AirPort Utility, located in the Utilities folder in the Applications folder.
Select the device you’re setting up, and then click Manual Setup. Enter the password if necessary.
Type a word or phrase in the search field.
Select the setting from the list to move to that setting.
