My iPod Touch, iPad and MacBook have lost the Airport Express located only feet away. All software is up to date, and when I go to Airport Utility it tells me the connection (through a Time Capsule) is good, so the problem is obviously with the Airport Express itself. I have turned it on/off, reset it, and reset it while turning on/off. This has happened before, and eventually it somehow reconnected itself, but not this time. What to do next?
