I was wondering what others have experience with Airport Extreme longevity? My first AE was purchased about 2008 not exactly sure, it has the power brick built into the power cord and 2.4 Ghz WiFi speed. This has been continuously in use since it was purchased. Today the WiFi quit but the ethernet ports are working. So I can not use the iPad or Macbook but an iMac and Mac Pro connected by cat5e cable work fine. In June 2012, I bought a new AE that had the dual band WiFi. This new AE replaced the old AE and used the old AE to extend the WiFi network. The new AE lasted just over a year when the internal power supply failed. Tonight I ordered a new AE. The third one in 6 years. What have others experienced with Airport Extreme?
