I have an airport express wth the cable modem hooked up directly to the ethernet port, and then the AExpress plugged into the wall. I am using a PB G4 to connect to the network, and using version 4.2 of Airport. At first I was setting up my airport express in the closet, and the LED was blinking amber and wouldn't allow my PB to see it as an available network. So I brought it out of the closet in to the open and got my network set up beautifully. Then, I unplugged the airport express to put it in its permanent position, but this time after plugging it back in, I was able to long onto the network but can't get to the internet now and the LED is blinking amber again, no more solid green. This second time around im positive it isn't interference, i brought it out into the open room with nothing around it, we dont have any 2.4 Ghz phones, no cordless phones at all actually. Im stumped, I have no idea, I tried turning on interference robustness and even changing the channels in Airport Admin Utility, but to no avail. Any ideas?
