By "works great" I mean that the rate decreases when I move far from
the access point and increases back when I get closer to it.
And when I don't move the rate seems to stay steady.
I'm testing a rate adaptation algorithm there, not becnhmarking the
maximum throughput of the adapter when locked at 54Mbps.
