New Airport Express is not discoverable by Airport Utility

Hello,

After searching the forums for a while and not finding any posts that really address the issue I'm having, I've finally decided to create my own post.

I received a brand new Airport Express from my girlfriend for Christmas. I've finally gotten some time to set it up, but I seem to be having some issues with Airport Utility even seeing it. I haven't even been able to set it up because I can't access it. Airport Utility simply says that it cannot find any Apple Wireless devices and continuously asks me to rescan.

The first time I plugged in the Airport Express, it flashed the green light once like it's supposed to, then the light turned to solid amber for a couple of minutes, then started blinking. It still does this even after I do a factory reset.

Very rarely Airport Utility will see it, but it takes a lot of rescans before it finally does. When Airport Utility does finally see it after several rescans, I enter manual setup, enter my information and click Update. After I click update, I'm no longer able to connect to the Airport Express at all until I do a factory reset. Then it takes a lot of patience and several more rescans until I can finally connect again.

I first placed it directly below my desk, but have since tried many other locations throughout the house to see if it was location that was the problem. That is not the issue.

The intention is to have it join my current wireless network, so I do not have an ethernet cable plugged into it. I've tried plugging one in, but with the exact same results (Airport Utility still can't see it).

Any ideas as to what may be the problem?

Thank you!
