Thanks that fixed the non-ge00 interfaces. As to the abysmal performance with macosx over 5GHz wlan, that still is there, but I suspect the macbok to be the culprit here (plus the wlan connection is somewhere ion the edge between changing transmigrates so might be a moving target).
Many thanks

The rrul plots still are quite interesting, as I could nicely see anticoorelation between up and down bandwidth (shared medium)
