I could kind of understand this for short frames like Data nullfunc and PS-Poll, but why would we like to hard code Probe Response frames to be sent at the lowest rate? Shouldn't the frames be sent at a rate that is most likely to get them through and do so in a manner that does not use excessive amount of air time? -- Jouni Malinen PGP id EFC895FA
