No changes. I will check the v5.2.2.4 tomorrow again. Maybe it does not use HT mode so often and that's the reason why the problem is not occuring that often... As a workaround: What about checking the IP length field. If the received packet is smaller by 4 bytes than what it should be then just add extra 4 bytes at the end? Or does the MIC at the end have any influence on anything?
