The sample rate control algorithm is much more responsive than the onoe algorithm. Can't comment on the timeouts w/o more info. Comparing the Atheros ndis driver isn't entirely fair as it will automatically switch between normal operation and XR mode at those signal levels. SamReceived on Thu Jun 16 2005 - 03:48:14 UTC
