When I purchased my Asus Rt-N16 I knew that it did not support dual radios (ie., if connecting a G device and N device at the same time under "mixed mode", then all devices connect at the lower speed). I was OK with that concept as my Wii supports G only. After flashing with Tomato, I noticed in the device list that my G devices are all at 54Mbps but, my N laptops are connected at 160-280Mbps. How is this possible? I know that the chip in the RT-N16 can support dual radios but I am under the impression that the feature is unavailable due to the circuitry. Am I totally mistaken that the purpose of dual radios is to simultaneously support N devices at N speeds while supporting G devices at G speeds? Can someone please shine some light on this for me? Dont get me wrong, I am ecstatic that I can get N devices to connect at higher throughput, while older G devices are connected but, that was a feature I thought I would have to do without when I bought this router.

I don't understand your question? Of course it cannot transmit at two speeds simultaneously. Neither can you shout and whisper at the same time. First, you do one. Then you do the other. Then you switch back. It takes milliseconds. Why would you need two radios?
Dual radios support two different BANDS.
