[ath9k] cannot authociate in wireless network

[DongHwan Jung]

hello, iPXE contributors.
I try to connect to AP by using wireless network but it's unexpected operating.

My action phase--------------------------------------

-In Linux -------------------------------------------

make bin/ipxe.usb DEBUG=net80211,wpa_psk:3,wpa:3
sudo dd if=bin/ipxe.usb of=/dev/sdb

-In iPXE --------------------------------------------

if you worder about more detail, refer to youtube video(https://www.youtube.com/watch?v=4pgzQaxqViQ)

I wanna settle this problem myself...
many times printing log, again and again fixing and operating ....
but, I can't solve this problem.

I gracefully plead with you to solve this problem.
thank you.

If it helps, reason 14 is IEEE80211_REASON_MIC_FAILURE.

Sorry, I don't understand your advice.
I have googling 'reason mic failure' but I cannot get helpful information.
Excuse me, do you watch the attached youtube video?

In addition, i find strange phenomenon in this debug log.
That is-------

Quote:WPA 0xdb9d8 A1 1c:65:9d:7f:4eBig Grin3, A2 1c:65:9d:7f:4eBig Grin3

--------------
this log is derived function 'wpa_derive_ptk()' in 'net/80211/wpa.c'
A1 is 'ptk_data.mac1' and A2 is 'ptk_data.mac2'.
I think A1 sending to A2 and A2 receive from A1
but A1, A2 are same MAC ADDRESS!!
Umm?? what does phenomenon mean?
is A1 sending to itself, A1 receive from itself?
I think the wrong understanding?

I continues to find out the problems... but if you know that,
inform me the solution.

thank you.
