This one is in half-mbps, so a value of 108 should give you 54m. The only thing I can think of right now is that the device (or channel) is actually configured for 11b not 11g mode. Can we rule that out? Which device are you using? > I am doing nanosleeps in between transmissions as if I don't the bpf clone > can't inject due to the buffer being too full.
