Hi Sean,

to my mind it look promising since the correct modules appear to be
loaded. Maybe you could comment an how you try to establish the
connection. I usually prefer to use the NetworkManager.

https://wiki.archlinux.org/index.php/NetworkManager

base package is "networkmanager",
for Gnome: "network-manager-applet"
for KDE: "kdeplasma-applets-plasma-nm"

I think (but I am unsure) you should stop all netctl services running
before trying the following commands.

Start the daemon (cases are correct this way):
# systemctl start NetworkManager.service

If you wanna use cli:

List of devices:
# nmcli con list
Connect:
# nmcli dev wifi connect <name> password <password>

If it is working enable the daemon on boot:
# systemctl enable NetworkManager.service

Best wishes,
Max
