The advertised rate set should be initially set according to the capabilities of the device. There were no devices > 2x2 when I wrote the code so MCS15 is the max. To support such devices you need to do more than just grow the rateset. Making the rate set user-controllable would be ok to add but probably used only for testing. Sam
