Airport Express

When having difficulties accessing the AirPort thru the AirPort Utility, try the following, in order checking accessibility with the utility after each step:

o Check the local connection. If you are trying to access the AirPort wirelessly, make sure that you are connected to its wireless network before running the AirPort Utility to administer it. If you are still unable to access it with the utility, temporarily connect your computer directly using an Ethernet cable to the base station's Ethernet port.

o Power cycle the base station. Remove the power adapter's plug from the power outlet, and then, wait 15 seconds before plugging it back in.

o Perform a "factory default" reset.

Hi, im pulling my hair out. im a techophobe but did manage to set my last airport express up. just got a new laptop. trying to get this express running and configured but my laptop doesnt detect the express base station. Even when using an ethernet cable this doesnt detect anything either? any advice?

This is a bug, and from my understanding its caused by the last firmware update/AP utility update.

I'm having this too at http://discussions.apple.com/thread.jspa?threadID=2031252&tstart=0
