If changing the tx rate control algorithm really fixes it then that says 
sample may be handing back bogus rate codes.  Since I can't make this 
happen someone else needs to dig.

As to better performance, onoe is not especially good and I do not 
recommend it.  However sample is too aggressive on up-shifting the tx 
rate and tends to vary the rate too quickly so can degrade performance 
when signal deteriorates.  I have done extensive testing of all the rate 
control algorithms as well as a proprietary one and chose sample as the 
default.  However none are anywhere near as effective as the proprietary 
one.
