Rates > real life maximum rate give similar performance since they all max out at that real life maximum rate (whatever that may be in your case). When lowering the stick's rate to rates < real life maximum rate, it's expected that the rate you experience is approximately the same as the rate you configured. (You should see more significant differences when lowering the rate even more) Your real life max. rate seems to be ~ (267MB*8) / (3*60 + 30) = 10.1 Mb. If I'm not mistaken you'll only see significant differences when lowering the rate below 10Mb. BTW when I was using linux-2.6.18-rc4 / wpa_supplicant 0.4.8 a couple of months ago I got a performance of ~ 1.3MB/s => ~10.4 Mb. This was approximately half the performance of the vendor driver. ------------------------------------------------------------------------- Take Surveys. Earn Cash.
