Throughput is much improved. I really hope it wasn't just a reboot that fixed it, but too burned out to do more tests today. I still see better TCP throughput with WPA2 when using 25-200 stations/streams. For anyone who wants to wade through some big automated reports, see the links near the top of this page (suggestions for improving those reports are welcome): http://www.candelatech.com/lf_wifi_examples.php (The 600 station reports are a bit dated and were done in a fairly busy wifi environment. We'll re-run those sometime soon-ish.) Thanks, Ben -- Ben Greear Candela Technologies Inc http://www.candelatech.com
