Well, I'm using the original drivers from 3.0.

Where does this output come from? I don't know it. You could use netperf
for testing the bandwith.

#!/bin/sh

dest="your_srv" # set the servername

while true ; do
netperf -t TCP_MAERTS -H $dest
netperf -t TCP_STREAM -H $dest
netperf -t TCP_SENDFILE -H $dest
done

Start netserver on the server side before you start this script (script
can be stopped with CTRL-C).

I'm using hostapd from hostapd git from 21.04.2011.

Sorry - I don't understand you :-(.
