I have had just about every generation of Airport Extreme. My place is just under 1,000 square feet. In other words, it's small. Nevertheless, I can never get the Airport Extremes to get me a good signal to my living room with my Mac Mini and Apple TV. Therefore, I upgraded to the newest, 5th generation Airport Extreme. It is said to be the greatest yet, with improved performance. Well, still, not so great. I get about 1Mbps speedtest.net on my Mac Mini whereas my net connection in the rest of the house is 4.5Mbps. Can an Airport Extreme really not work in such a small place? What do people do that actually have a large home? Yes, I have tried using Expresses to extend it and whatnot too, with not much better results honestly and just more complication.
