AP mode power save was broken for a time in 7.x (IIRC the aging of frames on the PS q was incorrectly calculated causing them to be tossed prematurely)--but that was unrelated to WME/WMM. > >> Unlikely.

WME should be immaterial to FreeBSD unless crypto was involved in which case you might've hit a bug w/ h/w crypto+WME that's long since been fixed (certain ath parts require the MIC be handled in s/w when WME is used). The best thing to do wrt FreeBSD is run 8.0 or later for much better wireless support. Sam
