I believe this was the last generation of wireless router that Apple made. I think I bought it around 2013. It still works great and covers my entire 3-story, 2600 sq.ft. house, but I like to stay ahead of the curve, so I upgraded and no longer need this. Always worked perfectly. I was using this up until about a week ago.
