AirPort Express blinks amber, even after reset or restart
I've had an AirPort Express (model A1392, fw 7.6.4) extending the wireless network of my AirPort Extreme (model A1143, f/w 7.6.4, connected to cable modem) without any issues whatsoever, for over a year.
About two weeks ago, the Express started giving me the amber blinking light, and AirPort Utility (v 6.3.1) told me that the Express "was unable to extend the wireless network." I reset and newly configured the AirPort Express several times. I moved the Express right next to the main base (AirPort Extreme). 2-3 times, I got the Express to show a green light and extend my network successfully again. But most of the time, when I plug the Express in at a new location or simply restart it right next to the main Extreme base, I get the amber blinking light again. 😕
The hit-or-miss nature of this is frustrating. Is my AirPort Express dead and I have to give up on it? Or is there a way I can salvage my AirPort Express? It's only 15 months old... 😟
