[SOLVED] Yet another Can't Connect to Wifi Thread

So I just bought a new wireless card (TP-LINK TL-WDN4800) and installed it in my desktop PC. It worked fine out of the box for a few days, but this morning I booted up the PC and now it refuses to connect to any networks. I'm using NetworkManager with Cinnamon and I can see all the local networks in the applet. I have tried to connect to both secure and unsecured networks. In either case, it tries to connect for about a minute then gives me the typical "Disconnected" message.

I tried disabling NetworkManager and using wifi-menu. It also fails. Here is the output of systemctl status netclt@...

● netctl@wlp3s0\x2dGarage\x20Mobile.service - Networking for netctl profile wlp3s0-Garage Mobile
   Loaded: loaded (/usr/lib/systemd/system/netctl@.service; static)
   Active: failed (Result: exit-code) since Fri 2014-12-12 19:06:04 PST; 20min ago

Dec 12 19:06:04 garage-desktop systemd[1]: netctl@wlp3s0\x2dGarage\x20Mobile.service failed.

It gives the same error for both secure and open networks.

Re: [SOLVED] Yet another Can't Connect to Wifi Thread

If thing were going, they should go again, unless you done/had modifications. Any update ?
Have you searched enough ?

You say that you are using NetworkManager, but in your code blocks, you are clearly looking at netctl status output.  You cannot have multiple services all trying to control your network at the same time... it will fail.

This is why its confusing. I don't remember doing any software updates, but I could be wrong.

I disabled NetworkManager before trying netctl.

In any case, it has decided to start working again for no apparent reason. Intermittent problems are the worst. Marking this thread as solved until it happens again.

That isn't a solution at all...

You want to use NetworkManager, but you still have netctl running.  It may be working just purely because the race condition worked out in the right way.  You need to figure this out before you mark the thread as [Solved].  if someone were searching for a similar problem and came across this thread, it would do them absolutely no good.

Just check the pacman.log against the beginning of you problem.
