What's _supposed_ to happen on channel change is this: * There's supposed to be an initial set of calibrations done, including NF; * the time-adjusted noise floor history for that channel is written out; * The last set ANI parameters for that channel are written out. The theory being that the NF and ANI results for a channel are channel specific and not global. _However_ this may or may not be correct or working correctly. ANI doesn't run for long enough during a channel scan to properly figure out channel conditions. But on a very noisy channel, you may need some specifically detuned parameters in order to receive successfully. This is why I was kinda hoping someone would step up and write some PHY visualisation tools. :-) There's plenty of counters from the Atheros MAC and PHY hardware; they just need to be logged and graphed! adrian -- To unsubscribe from this list: send the line "unsubscribe linux-wireless" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
