Hi there, So I bought my AirPort Express in march 2012. 2 Weeks ago it stopped connecting and the orange LED was constantly on (hardware failure). So, I sent it to an authorised Apple service. Today I got my AirPort Express back, but I'm confused whether they fixed my old one or changed it with a used one. First of all, the box looks like sh... It's all dirty, with a bunch of stickers glued to it. Then, when I looked at the router, there wasn't the scratch on the reset button I previously had. The serial number was different from the one on the box. This should mean that I got a different router, but when I launched AirPort utility on my Mac, it automatically recognised my old wi-fi network, which should point to the fact that it's my old router. Anyway, they could've changed the box that's why I have a different serial number. SO, what do you think? Is it my old router or a used one?
