Dear Javier
>From your rate value, You used 11g? now, I develop on 11n.
I am not test the 11g monitor throughput.
but in theory, monitor will the same throughput as ap-sta mode.
if not, maybe serverl reasons:
first, monitor mode will receive all same channel packets and give to click
FromHost.
maybe it's a bottleneck at the channel is very busy. ap-sta mode droped the
packet not itself at driver.
second, maybe your ap-sta mode use super-G mode. I don't analyse the super-G
frame.
but it should like 11n aggr. blockack will improve thoughput.
you can use omnipeek catch the frame ap-sta mode and monitor mode at
testing.
should comprehend thay frame difference. and optimize it.
I am very glad communicate with you, Thanks.
