For example have a look at packet # 1304, it is received immediately after 2/4 is acked, but 4/4 is not seen. After about 1 seconds the AP tries to send 3/4 once again (different sequence number), and only afterward 4/4 is send. However, in the log it looks like the first 3/4 is processed only after a delay of 1 sec., and this one is probably dropped by the AP. Note that after this the other 3/4 are received and are being processed, but no keys are installed, as the keys are already installed. You might want to check why the RX messages delayed in the driver.
