[SOLVED] Trouble using WiFi

Question

I haven't had problems with this before, but then again, I don't use WiFi a whole lot.
ArchLinux simply cannot use WiFi, even if it's connected. I'm not sure why that is. I am connected using the GNOME interface and what I assume is NetwokManager, although I'm not sure. I have done a lot of Googling but I can't seem to find any solutions, mainly because I don't know what is causing the problem.
Any ideas on what to do? How to diagnose the problem? How to fix it?

Answer 1

I know I needed to give some information, but my question also was how to diagnose the problem. I had no idea what to do still. Also for some reason GNOME seems to have stopped detecting WiFi networks as well. Not sure why that is, I've not changed any settings.

LOAD = Reflects whether the unit definition was properly loaded.
ACTIVE = The high-level unit activation state, i.e. generalization of SUB.
SUB = The low-level unit activation state, values depend on unit type.
102 loaded units listed. Pass --all to see loaded but inactive units, too.
To show all installed unit files use 'systemctl list-unit-files'.
