Bottom posting please. I have tried your change i still see the same issue.
Right after connecting i see that packets are encrypted but once it
unset/set "bitrates" plain packets are seen in sniffer.
BTW, i am not rebooting for each driver update, just re-inserting the module,
do i need to do a reboot for each driver change?
