On airo maybe, there is for example: __le16 linkLossDelay; __le16 maxBeaconLostTime; __le16 refreshInterval; which might have some effect on the firmware jumping to a new AP. Or it might just be the threshold at which the driver gives up and signals disassoc. TBH, I'm actually not sure about atmel, I forgot that their firmware is somewhat lighter than airo and orinoco. Later orinoco firmware versions might give up more control to the driver.
