Your posting truncated the note but what the person was suggesting was the station was operating in power save mode and so deferring transmits to the ap. Unfortunately that's not possible as HEAD has no support for sta-side power save.mode for ath. The original posting didn't provide any basic info so there's little anyone can provide except wild guesses. There are debugging mechanisms for tracing what's going on at the net80211 layer and in the driver that have been referenced countless times in this forum. Sam
