OK.... So i won an airport extreme 5th gen which is what it stated in the auction. I got the router in the mail today with the original packaging. The specs on the box indicated that it was the newest 5th gen with the model number but the model number on the router says A1143 which I think means that its the old router. And in airport utility it says that it is the 2nd generation router. Am I missing something? Or did I just get hustled?
