I have an Apple MacBook (retina, first generation). I have an Apple Airport Extreme (TimeCapsule in fact). Why can't they connect trouble free? After waking from sleep, I often have to switch off WiFi and then switch it on again to make the MacBook connect. I bought the airport extreme because I had that problem with other routers, but even Apple's own basestation didn't solve the problem. My other Apple devices have no problem connecting to my WiFi.
