I am a new mac owner - just purchased a macbook pro and set up an airport express to wirelessly stream music through my stereo. the set up was a breeze and everything worked great off the bat. a few hours in, the playback suddenly became extremely choppy, cutting out for 3 or 4 seconds every 5 seconds or so. I have my music stored on an external hard drive, so thought that might be an issue, so i restarted everything and just played music through the laptop speakers and it worked flawlessly. When i tried to stream it again, i had the same poor results? could it be some sort of interference? could it have something to do with my secure network? any help for a mac newbie is appreciated!
