Will need a lot of testing though. | | This is a big improvement, thank you. Can you say what "works great" | means? I just tried a couple of ural sticks and they max out at ~13 | Mb/s for upstream tcp netperf to an 11g ap in close proximity. This | appears to be the max for the adapter as locking the rate to 54M gets | about the same (though I don't see any way to get stats on what's going | on to see if there's room for improvement). | | Sam 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. Damien
