I have one SSID that is broadcasted over 2.4 and 5GHz.; 2.4GHz supports B/G and N; the 5GHz supports A and N. Since it is the same SSID, the Mac has a choice of which band and which standard to pick from. Does anyone know how OS X handles which band and which standard to use? If I reboot the same machine, it can decide on a different band and even then it may not pick N over B/G or N over A. Ideally I would like to have 5GHz picked over the 2.4GHz and then have it use N if available. It seems that Apple hasn't provided this capability within OS X. Anyone have any suggestions or hacks to try?
