I use an Airport Extreme(old one) for my wireless (working fine) and this AX for streaming music. I looked up help from (Apple/Support) and pushed down the reset button and followed the instructions using the Airport Setup Assistant. It "saw" the express, let me name it, and let me assign it to it's function of steaming music (rather than extending my wireless range). It turned solid amber for awhile, then rather than turning green it returned to blinking amber! I tried it again, this time unplugging/plugging in my modem/AE first but no luck. Any ideas? Is it a setting on my base station (AE) that I need to adjust? Maybe it's just busted. Thanks for any advice.
