[Solved] Trouble with WPA/WPA2 and wireless connections (ath9k)

Hi, I'm having some issues with my Arch install. Right now I'm posting this from Windows so I don't have precise logs, but I mostly remember the issue so bare with me.

I'm using ath9k with my Bigfoot Killer 1202 card (not sure what the exact model is), and I can't connect to my university's WPA/WPA2 access point. Using wpa_supplicant I get the error "4-way handshake failed - pre-shared key may be incorrect".

So after some digging I found that I can get it to authenticate with nohwcrypt=1, but when I rmmod ath9k && modprobe ath9k nohwcrypt=1 it enumerates itself as wlan0 (instead of wlp3s0, which is what I get from booting up).

Then I made the file /etc/modprobe.d/ath9k with the contents "options ath9k nohwcrypt=1" but it seems to still not want to connect until I rmmod && modprobe manually.

Can someone point me in the right direction on how to fix this issue? I haven't used Arch in a few years and a lot of things have changed, and so far it seems nothing works as I expect it to. Also, how do I get my wifi card to enumerate as the same device no matter when I load ath9k? I don't care if it's called wlan0 or wlp3s0, I just want it to stay the same.

Edit: Additional Info

cat /sys/module/ath9k/parameters/nohwcrypt

[root@huxley pobegam]# cat /sys/module/ath9k/parameters/nohwcrypt 
0

(so I guess it isn't loading from ath9k.conf on boot after all?)

Re: [Solved] Trouble with WPA/WPA2 and wireless connections (ath9k)

Update: It seems to work ONLY when I rmmod && modprobe; if I force nohwcrypt=1 at boot it doesn't seem to work. Seems kind of odd... Wonder if this is a kernel issue?

Edit: Also updated with dmesg (because I'm an idiot and forgot to include it)

Edit: I ended up solving my problem -- the issue I was running into was that ath9k was baked into my initrd without nohwcrypt=1. I opted to `mkinitcpio` again without MODULES='ath9k' -- alternatively, you could add a modprobe.d file to FILES= to get it to work, but I just figured this is simpler.
