Losing connection on Airport connected iDevices
I have an Airport base station connected to a cable modem. My iMac, iPhone, iPad and AppleTV (1st gen.) keeping losing connection even though the signal strength says excellent. Restarting the modem and Airport does not help. The only thing that helps is restarting the iMac, then all other devices connect immediately. This makes me think that the iMac or some piece of software is causing the problem. The problem did not start until two AE software updates ago. I downgraded the AE with older firmware but the problem persists. It is getting very frustrating. Airport Utility shows a good connection the whole time.
AirPort Extreme 802.11n (5th Gen)
