You're right, I did accidentally filter out acks. I have an updated
filtered capture attached.

It could be either, but I'm going off of wpa_supplicant instructing to
transmit the 2nd EAPOL frame, but it never showing up in the air. The
consultations I've received so far indicated that it would more likely be
a driver/firmware issue, but I don't have enough experience with Linux
supplicants to be sure about that.

For the client that I have in that thread, the info is the following:

Intel Centrino Advanced-N 6235
iwlwifi with iwlwifi-6000g2b-6 firmware
kernel is 3.11

The other user I'm working with I know the chipset is an Intel Centrino
Advanced-N 6200 with iwlwifi, but I don't know the firmware and kernel
version. I can request that info from the user if you deem it relevant.
