Sorry but this is true. With the dd-wrt firmware on the WRT610N it reports the exact speed the wireless is operating at. So the 2.4ghz band which I have configured as a b/g/n mixed mode it only connects at 54mbps because of my wireless printer. But the 5ghz band which I have set as N-only reports at over 240mbps.
