I guess I would be interested to know if there are any obvious differences in the streams. E.g. taking a monitor mode capture near the receiver should show whether the received power is similar, whether the # of retransmissions is significantly higher in ath5k vs madwifi, whether packets are sent at the same bitrates, if there are any pauses where ath5k doesn't seem to be doing anything, etc. Would it be possible to do a few captures with your setup? -- Bob Copeland %% www.bobcopeland.com
