The statistics for the mistrel algorithn are presented in the /sys
tree in a file named rc_stats. The easy way to see that data is to do
the following:
STATS=$(find /sys -name rc_stats)
sudo cat $STATS
You will get output that looks like

These data are for my RTL8187, which is running at 54 Mb/s (the line
with the T) and the success rate at this speed is 6220/6400 (97%).
Let the mistrel method go through several of those cycles that you
mention and then dump and post this table. Perhaps the experts will
see what is wrong.
