yes, I wrote the last email just to say that I have found something to look=
 at.
That is of course in the host driver. So the thing I did was reading
commit logs of the 2.6.32 kernel working well.

The only thing which puzzles me is the 5.5Mb/s data rate iwconfig shows.
After playing with the host side driver, it also shows higher rates. But
why does host driver affects *that* data rate of link qualitiy is good?

Thanks for all your ideas where to look at.

Greetings
Andreas Kemnade
