Unfortunately, my MacBook’s screen began to flicker (known problem) and the Airport card has issues connecting to networks (note that I said plural networks – tested it to make sure it wasn’t just mine).  Fortunately, I am still under my 1 year warranty.   I figured my best bet was to take it to the Apple store and drop it off for service.  Ain’t that simple.  First you have to make an appointment;  I can live with that.  But the real hook is when you get there at the specified time you sit around wondering when your next.  They have a screen that displays your place ‘in line’, but the employees don’t give you a time gauge.  I eventually gave up (after about 20 minutes of having zero communication) and called Apple’s tech support.  If you’ve got a tech problem and you’re under warranty I highly, highly suggest this.  Apple sent me a prepaid box direct to my door within two days.  No line, no silly questions and no need for patience.
