Open AirPort Admin Utility, select your base station, and click Configure.
Click Base Station Options, and then click Logging/NTP.
Select “Send Base Station Logging to” and enter the IP address of the computer that will receive the base station logs.
Choose a level from the Logging Level pop-up menu.
Select Set Date & Time Automatically and choose a Network Time Protocol (NTP) server from the pop-up menu. You need to assign an NTP server so the log information contains the accurate time.
