And that is all good. What is not, however, is the problem I have found in all of the dual-band routers I've worked with: the range of the 5Ghz frequency is shorter than that of the 2.4Ghz frequency. Often, the 5Ghz throughput performance is not much faster that of the 2.4Ghz, either. Also, though the dual-band routers have been out there for a year, there are still very few adapters/clients that support the 5Ghz frequency. And those that do tend to also support the 2.4Ghz frequency.
