I bought an airport extreme recently. I have enabled dual channel on auto mode (2.4Ghz + 5Ghz, a/b/g/n) My mbp is connected to the 5Ghz network, while the iPhone and iPad is connected to the 2.4Ghz as it only support that. When I loaded up the Airport Utilities, I can check the details of each wireless client. I noted my mbp connected speed is 300Mbps, while the iPhone and iPad is only 65Mbps. iPhone and iPad are wireless-n devices, why is 2.4 Ghz and 5Ghz network has such big differences? It seems to me the speed is only at wireless-g instead of n.. Did I have the wrong settings?
