I need to daisy chain 2 APE's together to increase the range for music playback.
We can tell you exactly how to do this with a step by step approach, but we need more information from you in order to provide the correct instructions.
1) What are the model numbers of the AirPort Express devices that you have? If you are not sure, look on the side or bottom of the device for the model number. It starts with an "A" followed by four numbers.
2) When you say "daisy chain", does this mean that the AirPorts will connect together using a wired Ethernet cable connection.....or.....will they connect using wireless?
3) What operating system do you have installed on your Mac? if you are not sure, click the Apple icon in the upper left corner of the screen, then click on About This Mac and post back with the OS X version number that you see there. Or, are you planning to use an iPhone or iPad for the setup?
