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.

I met a problem when I set to 5Mhz
Mode A can't work...
Do you have some ideas on this issue?
Best Regards.

Ohh. Ok. Yeah then it's most likely a driver bug. Hmm. I vaguely
remember bugs like this but I thought they were all fixed.
Is there any chance you could try to put the particular AP into 2.4 GHz?
Although I guess you have similar APs on 2.4 GHz channels that work?
Could you (or the user actually running into the problem) collect
tracing maybe?

STOP! Don't hijack other threads, keep your own. Otherwise I'll just
have to add you to a blacklist and never see email from you again.
