Having an issue trying to set up my Airport Extreme (A1521)
Recently purchased an Apple Airport Extreme (A1521) and trying to set it up so that I can use TIme Machine on a wireless network. After following all of the set up directions, the Airport Extreme is showing a blinking amber light on the front and it never turns to green. I would like to use the Airport Extreme as a stand-alone network... any suggestions on how to resolve the issue (to turn that amber light to green). Please advise... Thanks!
