I bought an airport express about 2 months ago, it was working perfectly until today when it stopped working all of a sudden. It doesn't appear in my wireless networks list and it doesn't appear in airport utility either. The light is constantly amber, never flashing and it only turns green for a second after turning it on, then goes back to amber. I tried to do a hard reset but it doesn't flash the 4 green lights. It just flashes amber for about 15 seconds and then the light turns off completely until I let go the reset button, then it goes back to the constant amber... really strange. Any suggestions would be appreciated.
