One strange thing. Can I ignore this waring, even if I think the wifi driver is ok?

Consider overriding the throughput manually or checking your driver.

I would say that you cannot ignore it because it means that the wifi driver didn't provide the expected throughput for a station.
But it is most likely better to let Marek and/or Antonio answer this question.
Btw. please structure you mails better. I will not read through this 400KB+ text mail just to find your annotations and questions. One which I saw but which should be answered by a different person is "6-node case".
Kind regards, Sven
