Joe, got the AE, just wiped out.

I have it plugged in with amber blinking in the other room.

I got airport utility set up manually, to extend network. did all security stuff etc and just wont connect.
Lot updating and tinkering.

Now it just says it's unable to find any airport wireless devices.
Manual setup is greyed out. Everything is greyed out.

I assume I'm not supposed to run a 30' Ethernet cord from one room to another correct?

The airport is plugged in just one room away. Totally lost.
