The changes are What environments are you seeing this bad behaviour in? I'd just like to be sure that this won't mess up the behaviour of ANI for other chips, other environments and other operating modes. > * Irrespective of opmode, the Weak Signal Detection is with the current > immunity level value. I didn't think that weak signal detection was a single bit in the PHY. It looks like you've just deleted all the threshold settings and are turning on/off using low self correlation. Have a read of the (very early, AR5212 era?) ANI patent: http://www.freepatentsonline.com/7349503.pdf If this has changed (ie, if in Osprey it's done differently) then it should likely be documented in the driver somewhere. IF this all works then great, but I'd really like to try and better understand/document the "why" aspects of it. ANI is .. fiddly, and there aren't any tools available for ath9k (+freebsd) wireless developers to really understand the impact of ANI.
