I just tried to set up my fancy airport express, upgrading my router from a g to an "n". Though hooked up properly with the ethernet cable straight from the router as directed, the new airport just blinks the amber light, and my airport utility says it can't find anything. The troubleshooting says it might be my internet connection, but its not that, the old linksys router works fine. I've tried all the tips from the manual, unplugging it, etc., but the airport does the same thing each time, just a blinking amber light, and airport utility can't find anything, it says no devices can be found. Is it a bad device or am I doing something wrong?
