I recently bought a simultaneous dual band Time Capsule / Airport Extreme and have noticed that the if you have the radio in auto or any setting with both 2.4 and 5ghz antennas supporting N, the router will drop you down from 5ghz to 2.4 as you move away from the router. As long as both antennas have the same SSID. This makes sense as the range of 5ghz with obstructions is worse than 2.4ghz. However, my issue is once you drop down to 2.4ghz, it will never automatically bump back up to 5ghz, even if you move back and you're just 1 foot away from the router. Operating at 300mbps and 450mbps is a huge difference. If this is the case, what is the point of having two antennas with the same SSID. Isn't the point so that it can swap back and forth as you move in and out of optimal range? Is it just me or is there something I'm missing.
