Hi Jouni

Thanks for your reply. Sorry for my late one.

I have made an interesting observation. After using a clear text psk in 
wpa_supplicant.conf, everything works as expected. I have attached two 
files where clear.log contains the output of `wpa_supplicant -ddd -Dhostap 
-c /etc/wpa_supplicant.conf -i wlan0` with clear text psk and hex.log with 
the psk generated by wpa_passphrase. Line 128/clear.log shows that a 123 
byte message has been received whereas line 127/hex.log indicates that 
only 99 bytes have been received.

Although my problem is now solved, I am very interested in the reason for 
that. Maybe the logs are helpful to you in this respect. If you need 
further information, please let me know.

There is one more issue, I would like to know. Do the log files or 
`hostap_diag -a wlan0` reveal any information that makes breaking the 
encryption easier compared to sniffing the packets?
I noticed several "[REMOVED]" tags in the logs so I guess it is at least 
not obvious.


Best regards,

Thomas
